The purification of gas from Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2) is one of the most pressing problems in the biomethane power plants and in the entire oil production and refining industry. Today, there are the following main methods to purify biogas: the method of liquid (wet) and solid (dry) chemical absorption of impurities...
Biogas to support Energy Transition Supporting the energy transition, GroupATP has developed the engineering for the pre-treatment of small scale bio-LNG production facility. In order, for the biomethane, to be liquefied, the content of H2O and CO2 shall be within pipeline specifications (in particular dew point -70°C). GroupATP has used combined membranes and PSA technologies...
