Integration of Biodiesel and Biogas Plants for Cost Effective Bio fuel Generation

Bio fuels such as biogas and biodiesel attract increasing attention all over the world as a substitute or mixture for fossil fuels in automobiles. Transesterification is the process that is used for producing biodiesel which is accepted worldwide because of its efficiency. Transesterification is the process done for decreasing the viscosity of the vegetable oil. In this paper, we have used Transesterification of cottonseed oil to produce biodiesel. The cost of production of one liter of biodiesel from cottonseed oil is thrice the cost of the diesel per liter. The byproducts of Transesterification process are glycerol and methyl ester water-wash. Both of the byproducts are good source of Methanol content which can easily be converted into methane gas or Biogas (CH4). Also, the cottonseed from which the oil is extracted can be used for producing biogas. In this paper, the laboratory experiments for Integrating Biodiesel and Biogas Plants are studied quantitatively in detail. By integrating both biodiesel and biogas plant, it is a way of reducing the cost of biodiesel which can boost the use of biodiesel in future.
