BIOGAS PURIFICATION & ENRICHMENT THROUGH STEPPED SCRUBBING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
Biogas is produced by anaerobic digestion of degradable wastes such as cattle dung, poultry droppings, municipal solid waste, sewage water, etc. This anaerobic decomposition causes evolution of Biogas contain Methane, Carbon Dioxide, Hydrogen sulphide, and water vapor, Since the raw biogas have low calorific value and low intensity for ignition due to the presence CO2 , H2S and water vapor. Hence it is needed to enrich biogas by removing these undesirable gases to save compression energy and space in bottle and corroding effect, which can be done by stepped scrubbing. The scrubbing system is found to enrich methane about 95 % or more depending upon biogas inlet and water injection pressure. Biogas can be used for all applications designed for natural gas, assuming sufficient purification.ie: by extraction and separation of these impurities by scrubbing process, we can purify and enrich the percentage of CH4 in raw biogas make its compression and bottling enable. Biogas can be converted in bio CNG after enrichment and bottling LBG, it becomes just like CNG.
