"Precision engineering, attention to detail in site preparation and professional project execution meant the plant was unloaded and positioned in less than a day," said Phil Bodsworth, Contracts Director for Intelect Engineering Ltd, appointed by Purac Puregas to carry out the electrical and mechanical installation.
The plant in Wiltshire will upgrade up to 700Nm3/h of raw biogas from the anaerobic digestion of agricultural by-products to UK gas grid specification, producing enough energy to heat around 3,500 homes or to fuel CNG vehicles.
Purac Puregas says the CApure process recovers over 99.9% of the biomethane present in the raw biogas, by chemically adsorbing the CO2. The biomethane can be of high enough calorific value to be directly injected into the natural gas grid without the need to enrich with propane - saving significant costs.
The long life, biodegradable organic solvents used in the CApure process are part of a closed loop system, minimising water consumption.
