BIOGAS DECARBONIZATION AND PURIFICATION SYSTEM
BIOGAS DECARBONIZATION AND PURIFICATION SYSTEM



Introduction: Utilization of the Biogas produced from the organic waste, after Water removing,
impurity removing, Pressure increasing, Sulfur removing, Carbon removing, and then purify into
natural gas.

Purification of Biogas flow range : Above 500M3/h
