• ### Density of biogas digestate depending on temperature and

Density is one of the most important physical properties of biogas digestate to ensure an optimal dimensioning and a precise design of biogas plant components like stirring devices pumps and heat exchangers. In this study the density of biogas digestates with different compositions was measured using pycnometers at ambient pressure in a temperature range from 293.15 to 313.15 K.

• ### Calculating the Heating Value of Biogasdonntu

· The only impact of water vapor in biogas will have is to change the density of the biogas and thus the pounds of methane per cubic foot. The LHV is determined entirely by the pounds of CH4 in a cubic foot of biogas. If wet biogas were combusted in a bomb calorimeter and the resulting gases were allowed to cool to the original temperature there is no reason the initial water vapor in the biogas would condense. The high heating value would not be increased by the heat of condensation of the initial water vapor. Because the biogas
