ABSTRACT
This report explains all the viable technologies and methods to upgrade a biogas feed to a certain level of purity to compress, store and use as a domestic fuel. The increase in purity also lends itself to increasing the energy producing capability of the fuel.
The report starts off by considering membrane separation technology for the purpose of purification. With economic and feasibility objectives in mind, water absorption is decided upon as the most beneficial technology.
The conditions are then simulated in chemcad to get the ideal parameters for the process.
ACKNOWLEDGEMENTS
We are very much grateful to Dr.K.N.Ponnani, consultant and R & D of chemical engineering department, Bits Pilani K K Birla campus for giving us an opportunity to work under him and get guidance and knowledge throughout the project.
I extend my sincere to Deepak Ojha, instructor who helped us with chemcad for our simulations.
