Downflow Gas Contactor


Efficiently remove and recover up to 99% of Carbon Dioxide and Hydrogen Sulfide from biogases to deliver cleaner air and improve emissions performance

Our cutting-edge Downflow Gas Contactor uses a proprietary recyclable water-based ABSOLV solvent to capture and separate both CO2 and H2S from gases – with minimal power consumption and in a small footprint.

Instead of releasing these harmful components into the environment, separated and captured gases are of sufficient purity for commercial reuse.

This patented CO2 removal technology can deliver powerful performance in circumstances where Biogas Upgradation has not been economically deployable until now.

Environmentally Friendly

OSIL’s Downflow Gas Contactor requires minimal power consumption and uses water-based environmentally friendly solvents in a uniquely green & efficient process.

Filter more than 99% of CO2 and H2S from exhaust gases – improving air quality and delivering against environmental objectives.

Small Footprint

This innovative technology can be deployed in very compact designs – even in a Container-based form for maximum flexibility.

DGC has also been shown to work efficiently for even low volumes of gases – well below the levels other technologies stop functioning effectively

Simple Process Parameters

Most Carbon Capture technologies require either high pressure or high temperature.

Our DGC system is typically operated at 20-30 oC and at atmospheric pressure – simplifying the process and maximising efficiency

Implement Anywhere

Our flexible implementation options allow our Downflow Gas Contactor solutions to be deployed almost anywhere.

Whilst scalable to provide high performance when deployed on large industrial plants, the solution can equally be deployed in containerised form and has proven effective for small flows of 5 m3/hr – allowing it to be used to target specific sites of high pollution such as busy traffic junctions.

Whatever the scale of the problem or its location, our technical specialists can design a solution that delivers the performance you require.
