Renewable Gas Upgrading

Application Overview

Carbon dioxide (CO2) and other impurities must be removed from renewable natural gas (RNG) feeds – like biomethane and landfill gas – to meet purity specifications. Deep Co2 removal is typically required to meet >96% methane concentrations for use as a pipeline gas or for transortation fuel like CNG.


Drop-In Solvent Replacement

No new equipment or process changes are required.  Our proprietary APBS-CARBex solvent is a simple drop-in enhancement over current solvents, delivering better performance for Co2 removal.
