Abstract

|
|
|
The main objective of this experimental investigation was recovery from biogas generated in municipal and wastewater treatment plant. The polysulfone hollow fiber membrane was prepared in order to investigate the permeation properties of and . Permeability of in Polysulfone membrane was 11-fold higher than of gas. A membrane pilot plant for upgrading biogas was constructed and operated at a municipal wastewater treatment plant. The raw biogas contained 66 ~ 68 Vol % , the balance being mainly . The effect of the operating pressure of feed and permeate side and feed flowrate on recovery concentration and efficiency were investigated with double stage membrane pilot plant. The concentration in the retentate stream was raised in these tests to 93 Vol % .
