Carbon Clean has improved upon conventional solvents with our patented formulation of amines and salts — known as Amine-Promoted Buffer Salts (APBS).

This innovation has been developed into two widely-used commercial solvents. APBS-CDRMax® was developed to extract CO2 from flue gas in large scale industrial plants. APBS-CARBex® was specifically designed for biogas/RNG upgrading. These unique solvents can be used as either a drop-in substitute into existing systems such as biogas separation or used with an integrated carbon capture system.

APBS-CDRMax®

APBS-CDRMax® is a commercially-available CO2 capture solvent used for industrial flue gases or off-gases with CO2 concentrations ranging from 3-25% by volume.

The solvent can be paired with our CDRMax® process, or used as a drop-replacement for alternative solvents such as MDEA for low pressure gas separations. CDRMax produces CO2 with a purity of 95–99.9% and offers a $40/tonne cost of capture when used with our CDRMax process.

APBS-CDRMax® has high solvent stability, low corrosivity, low regeneration energy requirements, and holds up well in oxygenated environments. As a drop-in replacement, APBS-CDRMax® can reduce energy costs. In conjunction with our CDRMax® process, operational costs can be reduced 20–40% compared to conventional options. 

APBS-CARBex®

APBS-CARBex® is a commercially-proven, widely-used proprietary solvent that reduces the cost of upgrading biogas or landfill gas compared to alternative technologies such as membranes or PSAs.

APBS-CARBex® uses thermal energy to remove CO2 concentrations of up to 50% volume from biogas and landfill gas streams at low pressure. Over 99% of the raw methane is recovered to produce pipeline-quality natural gas (RNG) or compressed natural gas (CNG).

Additionally, APBS-CARBex® can offer improved operating performance compared to alternative solvents such as MDEA, MEA, and DGA for CO2 removal systems operating at low pressures.
