Anaerobic Fermentation: Biochemistry and Kinetics | Biogas

In this article we will discuss about:- 1. Biochemistry of Anaerobic Fermentation 2. Microbiology of Anaerobic Fermentation 3. Kinetics of Anaerobic Fermentation 4. Hydrogen Production by Hydrogen Producing Bacteria of Digester Sludge. Biochemistry of Anaerobic Fermentation: Anaerobic fermentation basically involves three phases, namely, hydrolysis, an acid phase and the methane phase. Hydrolysis phase covers break-down of large molecules into smaller [...]

How to Remove Hydrogen Sulphide from Biogas? (3 Methods)

Hydrogen sulphide which is usually present in trace quantities in biogas is poisonous and harmful for health, and also imparts corrosive property to it. Process of removing hydrogen sulfide from gas is called desulfurisation. Like carbon dioxide, it can also be removed by water and caustic scrubbing. A brief description of some of the commonly used desulfurisation methods are as [...]

How to Remove Carbon-Dioxide from Biogas? (4 Methods)

Carbon dioxide being noncombustible constituent of biogas lowers its heat value. Removal of carbon dioxide is not necessary when gas is to be used for cooking or lighting purposes only. A number of methods have been developed for CO2 removal (scrubbing) which depending upon the technique involved are called water-scrubbing, caustic-scrubbing, solid absorption, liquid absorption and pressure separation. A brief [...]
