Biogas part 2

Biogas production of bacteria is a collaboration organic matter. Decomposition of organic material in the process of digestion is Called Proteus That Is Produced gas without oxygen, most (more than 50% methane). The organic material in the digester (reactor) to diuraiakan, often in collaboration with two types of bacteria. The first phase of the material in the acid-acid-acid, weak acid bacteria to help. These bacteria and the hydrolysis and asidifikasi level description of the waste. Hydrolysis of complex compounds, or long chain compounds, Standard and Poor 'the breakdown of fats, proteins, carbohydrates are simple compounds. In other words, the formation of acid and simple compounds.

The material is acid, organic acid, the second phase of the methane gas in the Digestive process of the formation of Proteus That methanococus Poor 'bacteria, Methanosarcina, in Cooperation with the methano as methane bacteria.

Proteus development of the Digestive process has been Successful in many applications. This ABILITY to process waste and waste products of interest to switch to the overflow value. Application of the Digestive system, Proteus, has been Successful in industrial waste, agricultural waste and animal waste and municipal solid waste (MSW) is the treatment.

Mostly Gs biogas containing methane (CH4) and carbon dioxide (CO2), and Some of Which contain a small amount of hydrogen sulfide (H2S) and ammonia (NH3) and hydrogen and (H2), Which implies very little nitrogen.

The energy contained in biogas depends on the concentration of methane (CH4). The higher the methane content of the higher energy content (calorific value) in the biogas, and conversely the Smaller the Smaller the content of methane calorific value. Biogas quality Can be improved by treating Some of the parameters are: Eliminate hydrogen sulfur, moisture content and carbon dioxide (CO2). Containing hydrogen and toxic substances That cause corrosion, if the biogas contains this compound will of cause a dangerous gas, so That allow the maximum concentration of 5 ppm. When hydrogen gas is burned the sulfur would be more dangerous form Because it will from a new compound together with oxygen, sulfur dioxide / sulfur trioxide (SO2 / SO3). This compound is more toxic. At The Same Time will of the form the Sulphur acid (H2SO3), a compound Which is more corrosive. The second parameter is the carbon dioxide That has a goal to improve quality, so the gas Can be Used to fuel vehicles. Water content in the biogas will of reduce the ignition point and cause corrosive biogas cans
