The Biogas Oil System

Biogas from landfill, sewage and other bio-materials suffers from variable quality of gas production. Very often, elevated levels of H2S mean degraded lube oils, shorter maintenance intervals and increased overall operating costs. Conventional solutions rely on scrubbing 100% of the incoming gas, with high capital and running costs for the scrubbers.

BOS is a new patent protected solution developed by engineers from Aquafuel Research Ltd and Gas Data Ltd.

After extensive field trials it has been shown to deliver cost effective protection to lube oils in gas engines.

It works by treating only the vital 5% of gas which enters the crankcase and does so for less than 1/10 of the capital and running cost of conventional scrubbing systems.

Operating within the terms of an exclusive licence granted by Aquafuel Research Ltd to Gas Data Ltd BOS senses and remotely monitors the H2S levels in the incoming gas and automatically adapts its dosing to match.

This means no waste of consumables through fixed rate over-dosing and no lube oil degradation.
