EnviTec opens French biogas plant with compression tech

Germany-headquartered biogas business EnviTec has opened its fortieth French biogas EnviThan upgrading plant, in Premierfait, France.

The customer, Biogaz des Vieilles Vignes, operates the 400 Nm³/h biomethane plant using a daily input of 100 tonnes of agricultural residues and the gas is fed into the local gas grid by NaTran (formerly GRTgaz).

Mehdy Benyahia, Managing Director responsible for plant construction at EnviTec Biogas France, said the initial feed-in was commissioned in July following a year-long construction period, and four reference plants were built within a 30km radius.

The plant also features on-site compression technology. “The outlet pressure of the biomethane can be flexibly adapted to the required grid pressure – 70 bar in this case – using booster technology,” he said.
