ABSTRACT
Water hyacinth represents a promising source for biofuel production because of their high availability and high biomass yield. The water hyacinth is also a noxious threat as a weed which clogs the inland waterways, canals, lakes, and lagoons, causing harm to the local flora and fauna, and preventing water navigation. Therefore, the abundant availability with the reason to efficiently utilize the weed opens a window towards production of biofuel from it. The water hyacinth contains high amount of cellulose and hemicellulose which can be chemically treated to yield sugars which can be fermented to produce alcohol. Subsequent distillation of this can yield highly concentrated bioethanol which can be used as fuel for homes, additive in petrol for transportation. The bioethanol produced from the water hyacinth also burns free of soot and smoke thus it is a clean source of energy too. Further research done on the subject also reveals that water hyacinth can also be used for the production of another biofuel, biodiesel. But due to the low yield, biodiesel production is usually disregarded. However, water hyacinth can be used to produce both the biofuels, but bioethanol is usually preferred.
The production of bioethanol using chemical pretreatment by mild acid hydrolysis and subsequent fermentation, distillation and analysis of products is thoroughly conducted by this work. This might probably help the community to successfully combat the threat caused by the water hyacinth and address the energy demand.

INTRODUCTION
Water Hyacinth (Eichhornia crassipes) is a monocotyledonous freshwater aquatic plant, belonging to the family Pontederiaceae, related to the lily family (Liliaceae) and is a native of Brazil and Equador region. It is also a well known ornamental plant found in water gardens and aquariums, bears beautiful blue to lilac colored flowers along with their round to oblong curved leaves and waxy coated petioles. It grows from a few inches to about a meter in height. The stem and leaves contain air filled sacs, which help them to stay afloat in water. In the developing world, it is used in traditional medicine and even used to remove toxic elements from polluted water bodies. They reproduce both asexually through stolen and sexually through seeds, which remain viable for up to 20 years and therefore are difficult to control. Thus, it is also considered as a noxious weed in many parts of the world as it grows very fast and depletes nutrients and oxygen rapidly from water bodies, adversely affecting flora and fauna. There have been instances of complete blockage of waterways by water hyacinth making fishing and recreation very difficult. Under favorable conditions water hyacinth can achieve a growth rate of 17.5 metric tons per hectare per day. There is a great discrepancy among policy makers, environmental agencies and research scientists on the way to control this invasive species and the practical benefits that can be obtained. There is a need for sustainability and a new perspective when it comes to managing this species and understanding and implementing their marketability as an ornamental or in their alternative products or as a newly found biofuel crop.
Water hyacinth is an invasive species, which invades freshwater habitats and is listed along with some of the worst weeds. Some countries have even placed this species in their quarantine list and banned their sale or movement within their sphere of influence. Water hyacinth is very difficult to eradicate by physical, chemical, and biological means, and a substantial amount is spent on their control annually throughout the world. It is also a very sturdy species. It causes blockage of irrigation channels affecting the flow of water to fields, gets entangled with motorboat rotors, making fishing difficult, and almost makes any place inhabitable and inaccessible. They may block hydroelectric turbines causing enormous damage, which are vital for the economy and green environment. They out-compete almost all other species growing in their vicinity thereby decreasing biodiversity. They destroy the beauty of a given place, and sometimes can be a breeding ground for disease causing insects and pests. They also can accelerate the process of evaporation from water bodies. They tend to absorb nutrients quickly thus making the ecosystems less fertile. This may have a large impact on the life of marginal farmers, increasing poverty in the less developed world.

Biological Attributes of Water Hyacinth for An Efficient Bioenergy Crop
Attributes of an ideal biofuel crop are:
1. Naturally grown vegetation, preferably perennials.
2. High cellulose with low lignin content per unit volume of dry matter.
3. Easily degradable.
4. Should not compete with arable crop plants for space, light and nutrients.
5. Resists pests, insects and disease.
6. Not prone to genetic pollution by cross breeding with cultivated food crops.
Water hyacinth is low in lignin content (10%) and contains high amounts of cellulose (20%) and hemicellulose (33%). A typical biomass from land plants can have 30-50% cellulose, 20-40% hemicellulose and 15-30% lignin. In plants, lignin (composed of phenylpropanoid groups) acts as a polymer around the hemicellulose microfibrils, binding the cellulose molecules together and protecting them against chemical degradation. Lignin cannot be converted into sugars. Thus, it is not practical in biofuel production. Their degradation is a high- energy process. Water hyacinth has low lignin, which means the cellulose and hemicellulose are more easily converted to fermentable sugar thus resulting in enormous amounts of utilizable biomass for the biofuel industry.
Page 3 Dept. of MechanicalEngineering,ASIET
Fig. 1.2. Water Hyacinth
Further, water hyacinth grows at a very rapid pace and contains very high nitrogen content. They can practically grow in any habitat and require little to no maintenance, but they prefer to grow in warm climates. Further, they can be used to purify water bodies containing high amounts of heavy metal contamination. The biomass can be used to produce biogas and the byproducts can be used as organic manure or for producing bioethanol by further decomposition of fermentable saccharides.
In addition, aquatic plants do not compete with land resources used in arable food crop cultivation and thus are an incentive factor when it comes to biofuel production. For the past few years, there have been reports of genetic engineering of microorganisms, which can increase ethanol production from hemicellulose by fermenting it into oligosaccharides also found that bioethanol generating capacity of water hyacinth can be compared to that obtained from agricultural waste, thus is a potential new crop for biofuel production and an employment generating industry.

OBJECTIVES AND SCOPES
To study the feasibility of water hyacinth as an energy crop and to isolate potential cellular strain of microorganism for the conversion of Lignocellulosic biomass into ethanol at lower cost with effective technologies by Eradication through utilization. Water hyacinth which is basically a water weed, is a social threat as it affects water transport, aquatic life etc. With industrial development growing rapidly, there is a need for environmentally sustainable energy sources. Ethanol from biomass, bioethanol, is an attractive, sustainable energy fuel source for transportation. Based on the premise that fuel bioethanol can contribute to a cleaner environment and with the implementation of environmental protection laws in many countries, demand for this fuel is increasing. Efficient ethanol production is based on optimized processes where utilization of cheap substrates is highly demanding. Utilization of different types of lignocellulosic materials can be considered for production of ethanol. Among various types of lignocellulosic substances water hyacinth (Eichhornia crassipes) is a potential resource available in many tropical regions of the world. It is a noxious aquatic weed which grows fast. A considerable amount of research work is in progress for its bioconversion into ethanol using two sequential steps of hydrolysis and fermentation. This project focuses on the bioconversion of water hyacinth to ethanol.
The backwaters in Kerala are filled with water hyacinth plants. Conventionally these water hyacinth are simply collected by hand and left to rot on the land, which could be used to produce manures. Also water hyacinth fibers are used in rope production. Although these productions are going on, the problems caused by water hyacinth are not reduced. Here comes the importance of a biofuel production from water hyacinth. As the reproduction rate is very high, the availability of raw material is abundant. A mechanized production of bioethanol is proposed in this project, which focuses on the biomass extraction from water hyacinth and the further chemical processes to produce bioethanol. The produced bioethanol can be blended with existing fossil fuels. This can replace conventional fossil fuels, which is economically and ecologically feasible. By the implementation of this project on a large scale,

social threats caused by water hyacinth is reduced as well as an alternate energy source is introduced.

THEORY
The water hyacinth is primarily a lignocellulosic biomass. Lignocellulosic biomass is mainly composed of plant cell walls, with the structural carbohydrates cellulose and hemicellulose and heterogeneous phenolic polymer lignin as its primary components. However, their contents varies substantially, depending on the species, variety, climate, soil fertility and fertilization practice, but on average, for agricultural residues such as corn stover, wheat and rice straw, the cell walls contain about 40% cellulose, 30% hemicellulose and 15% lignin on a dry weight basis.
The water hyacinth consists of about 10% lignin and contains high amounts of cellulose (20%), and hemicellulose (30%). A typical biomass from land plants can have 30-50% cellulose, 20-40% hemicellulose and 15-30% lignins. In plants, lignin acts as a polymer around the hemicellulose microfibrils, binding the cellulose molecules together and protecting them against chemical degradation. Lignin cannot be converted into sugars.
CELLULOSE
Cellulose is a polysaccharide composed of linear glucan chains that are linked together by b-1,4- glycosidic bonds with cellobiose residues as the repeating unit at different degrees of polymerization depending on resources, and packed into microfibrils which are held together by intramolecular hydrogen bonds as well as intermolecular van der Waals forces.
HEMICELLULOSE
Hemicelluloses are a heterogeneous group of polysaccharides with the b-(1?4)- linked backbone structure of pentose (C5) sugars, such as xylose and arabinose, and hexose (C6) sugars, including mannose, galactose and glucose as the repeating units, which have the same equatorial configuration at C1 and C4. Unlike cellulose which is crystalline and resistant to degradation, hemicelluloses are random and amorphous, and thus easily hydrolyzed to monomer sugars
However, hemicelluloses are embedded and interact with cellulose and lignin, which significantly increase the strength and toughness of plant cell walls.
Page 9 Dept. of MechanicalEngineering,ASIET
LIGNIN
Although lignin is a non-sugar-based polymer and cannot be used as feedstock for ethanol production via microbial fermentation, it exerts a significant impact on the economic performance of the corresponding bioconversion processes, since most inhibitors of microbial growth and fermentation come from this compound during the pretreatment that is needed to render cellulose amenable to enzymatic attack. Mean- while, as the second most abundant component in biomass after cellulose, lignin yields more energy when burned, and thus is a good selection for combined heat and power (CHP) production in an eco- and environment-friendly mode of the biorefinery. Moreover, lignin is an excellent starting material for various products including transportation fuels and value-added chemicals, which may add credits to bioconversion processes and make bioethanol more economically competitive.

EXPERIMENTAL SETUP AND PROCEDURE
COLLECTION OF WATER HYACINTH
The water hyacinth samples were collected from the outskirts of Kalady town.
Fig. 5.1. Collecting Water Hyacinth samples
PRETREATMENT
The collected samples were washed with running water to remove dirt and clay remains. Then the sample was set aside to drain any water left. The samples were then made ready to undergo pre-treatment. The pretreatment is important as it is an important factor that decides the final yield of the bioethanol. The samples have to be made smaller in size. The smaller the size, the more efficient the mass and heat transfer will be for subsequent pretreatment and enzymatic hydrolysis. However, power requirement increases significantly with reduction in size. Therefore, a compromise between size reduction and energy consumption is needed from the economic point of view. Pretreatment technologies can be classified in general into four categories: physical pretreatment, chemical pretreatment, solvent fractionation and biological decomposition. An ideal pretreatment process should maximize sugar yield from cellulose and hemicelluloses, and in the meantime minimize energy consumption and environ- mental impact. Unfortunately, none of them alone can satisfy all of these criteria. Thus upon consulting with the faculty, it has been suggested to carry on with the chemical pretreatment.

CHEMICAL PRETREATMENT
Chemical pretreatment involves breaking down of the lignin that holds together the cellulose and hemicellulose. The process is carried out in an acidic environment. Dilute acid pretreatments have been intensively studied over the years with various feedstocks and reactors at different scales.
Prior to chemical pretreatment, the samples are cut into small pieces. This is to increase the contact of acid with the surface of the samples. Outside the laboratory, on an industrial scale cutting the samples by hand is not an ideal way as it is time consuming and uneconomical. Therefore, equipment like compression screw feeder can be used to extract the cellulose. However, the size of the samples might vary but it can be neglected because on an industrial scale, one deals with large quantities of water hyacinth samples.
The sample was then dried in a hot air oven at 105C. To begin the acid hydrolysis ( pretreatment), about 10 gram of dried sample is mixed with dilute sulphuric acid ( conc. <2% ) and a solution is made with distilled water until the solid concentration reached 30%. This solution has to be heated up to 121 at 15 psi pressure. This is done with the help of an autoclave. The solution is autoclaved for up to 15 minutes and then cooled to room temperature. A special filter paper called Whatman filter paper No.1 is used to filter the product. The filtrate is collected. This filtrate is called acid hydrolysate. The acid hydrolysate is heated to 50C to remove any volatile components. Also chemical CaOH was added at 34g/l and agitated to detoxify the hydrolysate to provide a medium for the fermenting yeast. Also the addition of CaOH has increased the pH of the solution. To provide a pH medium that is habitable for the yeast, 10 M NaOH is also added. These procedures make up the chemical pretreatment.
Page 12 Dept. of MechanicalEngineering,ASIET
FERMENTATION
The pretreated water hyacinth sample was dissolved in 100 ml of distilled water and is sterilized at 121 for 15 mins. The fermenting enzyme can be either yeast or bacterium Z. mobilis. The solution was set aside to ferment and produce ethanol from the sugars that have been made by the chemical treatment of the celluloses.
Page 13 Dept. of MechanicalEngineering,ASIET
Chapter 6
RESULTS AND DISCUSSIONS
The distillation of the fermented solution yields ethanol up to concentration of 60%. To confirm the product IR spectroscopy is carried out. The IR spectrum obtained coincides with that of an ethanol solution, thus leading to a conclusion that the solution prepared from water hyacinth indeed yields ethanol.
The simplicity of the ethanol molecule means that the IR spectrum is relatively easy to measure and so it is possible to identify ethanol in a complex sample such as a breath sample containing water and other organic compounds. An IR spectrometer that is being used to detect ethanol will do so based on the absorbance of a specific peak. This is usually the absorption band at a wavenumber of approximately 3000 cm-1. The intensity of this signal in that region will be directly proportional to the ethanol concentration.
From the research, we can arrive at a conclusion that ethanol is in fact produced and further means of mass production can be thought about.

CONCLUSION
From the results obtained, it can be seen that bioethanol is a suitable solution to the energy issues faced by several countries. Especially those like India which has a shortage of crude oil supply and depend on imported oil for economical development. As a bigger scenario, the world is running out of fossil fuels and the need for a renewable clean source of energy is bigger than ever.
To cater for the ever so increasing demand for an energy source that'll replace petroleum, bioethanol comes into play. Water hyacinth is in itself a threat to aquatic ecosystems and the scope of producing energy from it serves the purpose. Efficient and clean source of energy is obtained on one hand and eradication of a weed that threatens the life of all aquatic living beings on the other.
As demand for energy keeps on increasing day by day, it'll be necessary to keep up with the growing need and to realize the fact that we'll need cleaner and larger sources of energy. Water hyacinth, for example, is available in abundance and is able to address the drastic increase in energy consumption.
However, although significant progress has been achieved in biomass pretreatment and cellular production , bioethanol is still not economically competitive compared with petroleum-based fuels, making cost reduction the biggest challenge.
To solve the problems of the conversion process, science and efficient technology are to be applied, so that bioethanol can be produced sufficiently to overcome the current energy demand from the petroleum sector.

Main Components
Compressor
The compressor, a central component in vapor compression systems, elevates the vapor refrigerant's pressure, increasing its temperature. Compressors are classified by their operation method (reciprocating, rotary, centrifugal, or screw) and drive type (open, semi-hermetic, or hermetic). Reciprocating compressors, like the one used in this project, are suitable for a wide range of applications, offering high compression ratios and compatibility with various refrigerants.
Condenser
The condenser is positioned on the high-pressure side of the system and serves to remove heat from the hot vapor refrigerant, transforming it into a liquid. Condensers come in various types, including water-cooled, air-cooled, and evaporative condensers. In this project, an air-cooled fin and tube condenser is employed for efficient heat removal.
Evaporator
Situated on the low-pressure side, the evaporator's primary function is to absorb heat from the surrounding environment, causing the liquid refrigerant to evaporate. Evaporators can take various forms, such as bare tube coil, finned tube, plate, shell and tube, shell and coil, or tube-in-tube. For this project, a shell and coil evaporator is utilized.
Expansion Device
The expansion device plays a pivotal role in dividing the high-pressure and low-pressure sides of the system. It reduces high-pressure liquid refrigerant to a lower-pressure liquid before it enters the evaporator. Several types of expansion devices exist, including capillary tubes, hand-operated expansion valves, automatic (constant pressure) expansion valves, thermostatic expansion valves, and float valves. The automatic expansion valve, which responds to system pressure changes, is employed in this project.
Refrigerants
Refrigerants are vital for heat transfer in the system. They absorb heat from a low-temperature source and dissipate it to a higher-temperature sink, either as sensible heat or latent heat. Refrigerants fall into two categories: primary refrigerants, which directly participate in the refrigeration process, and secondary refrigerants, which are first cooled by primary refrigerants and then used for cooling purposes. Selecting the right refrigerant involves considering its thermodynamic, physical, and safety properties, as there is no universal refrigerant suitable for all applications. Factors such as working pressure range, corrosiveness, flammability, space constraints, and required temperature in the evaporator must be considered when choosing a refrigerant.
CE 1.3.4 Charging of Refrigerant (Freon 12)
During refrigerant charging (Freon 12) in the vapor compression system, it's crucial to follow precise procedures. Evacuation and dehydration are critical first steps to remove moisture, air, and non-condensable elements. Moisture can freeze and block refrigerant flow, while it can also create corrosive acids. Hence, a high vacuum is drawn to prepare the system.
Charging via the suction valve gauge port is common for smaller installations. After evacuation, the process involves connecting a charging line, opening the cylinder valve, and letting the compressor draw in the refrigerant. It's vital to monitor and not exceed 2 bar gauge. After reaching 0 bar gauge, the system is ready for testing and operation.
CE 1.3.4.1 Refrigeration Accessories
Refrigeration systems use various accessories, like receivers, which store and supply liquid refrigerant to the evaporator. They're advantageous for system servicing and during long shutdowns to prevent gas leakage.
Driers
Driers are essential to remove moisture and particles in refrigeration systems. They consist of a shell with desiccant granules. The refill type is commonly used, with silica-gel being a popular desiccant.
Insulation
Insulation is vital to limit heat transfer in refrigeration systems. It reduces heat flow through conduction, convection, and radiation. Effective insulation has low thermal conductivity and small closed air cells.
Tubing
Copper tubing is a standard choice for refrigeration systems due to its good heat conductivity. It's available in soft and hard types, with type L being the common choice.
Soldering
Soldering is crucial in refrigeration work, especially when joining copper tubes. It creates strong connections that ensure system reliability and efficiency.
