Consequently, the change in carbon density from converting forestland to cropland would be -84.72 metric tons of C/hectare/year of biomass plus -3.60 metric tons C/hectare/year of soil C, minus 10.26 metric tons C/hectare/year from drained organic soils, equaling a total loss of 98.5 metric tons C/hectare/year (or -39.89 metric tons C/acre/year) in the year of conversion.Get A Quote

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestionGet A Quote
Jyväskylä Summer School 2013 % Methane of Biogas The % methane of the biogas is important for two reasons: first, the design of the gas utilisation system; and second, the mass balance. It is assumed that the balance of the biogas is CO 2. CH 4 has a density of 0.71kg.m-3. (This is on the basis that 1 kmol 3of a perfect gas occupies 22.4m ). CO 2Get A Quote

BIOGAS UPGRADING AND UTILISATION 5 Biogas can be used for all applications designed for natural gas. Not all gas ap-pliances require the same gas stan-dards. There is a considerable diffe-rence between the requirements of sta-tionary biogas applications and fuel gas or pipeline quality. Heating Boilers do not have a high gas quality requirement.Get A Quote
