Comparison of Biogas Purification by Different Substrates and Construction of a Biogas Purification System

The kinetics of biogas purification by the KOH solution has a fast and complete removal of CO 2 with a large increase in the calorific value of the purified biogas of order 2.7 kWh/m 3 compared other types of purification substrate. But this type of purification has a low speed of disappearance of H...

Description
Summary:The kinetics of biogas purification by the KOH solution has a fast and complete removal of CO 2 with a large increase in the calorific value of the purified biogas of order 2.7 kWh/m 3 compared other types of purification substrate. But this type of purification has a low speed of disappearance of H 2 S order 1.33 ppm/min. The purification of biogas by rust eliminates only and quickly of H 2 S with removal speed of 2.15 ppm/min and it don’t decrease the energy of biogas. Consequently, the construction of a filtration system which combines the two substrates (rust and KOH) can increase the calorific value and quickly remove of H 2 S from biogas purified. In order to have a high energy power of biogas and early elimination of corrosive elements.
