Biogas Purification for Power Generation

Since many years, Pakistan is facing the difficulties of energy shortage. Each year government is paying more than 14 billion US dollars on crude oil to complete the energy breach. Energy requirement is rising speedily however use of renewable energy is not sufficient to meet required need. In this book, the potential of biogas production and purification techniques are reviewed for power generation applications. Up to 2.5 KWh energy could be produced by 1 cubic meter of bio-gas. In the livestock sector, there is 4% growth rate in Pakistan on annual basis. The yearly growing rate of livestock sector is 4% in Pakistan and its manure can yield 35.5 GWh of electric energy daily. Energy crisis can be sorted by efficiently using bio-gas up-gradation as an alternative energy source. Different techniques of biogas purification for all the applications designed for natural gas were studied and reported in this book. Biogas purification experiments were conducted using chemical absorption technique on a pilot plant of biogas. The upgraded biogas could be utilized for the purpose of Cooking, Heating, Lightening (gas lamp), Electricity (generator) and Bio fertilizer.
