VALORIZATION OF BIOGAS THROUGH SIMULTANEOUS CO<SUB>2</SUB> AND H<SUB>2</SUB>S REMOVAL BY RENEWABLE AQUEOUS AMMONIA SOLUTION IN MEMBRANE CONTACTOR

Abstract

HIGHLIGHTS• Simultaneous H2S and CO2 removal from biogas is studied.• Renewable absorbent from biogas slurry is used in membrane contactor.• More than 98% of H2S can be removed by membrane absorption.•The impurities have less influence on H2S removal efficiency.
