Eco-friendly water treatment solution for the Fos-Cavaou LNG carrier terminal
Reducing the environmental impact of the Fos-Cavaou LNG terminal with a biodegradable, biobased water treatment process
CONTEXT & ISSUES
Implemented by Elengy in partnership with Polymaris and ENGIE Lab Crigen, this new regasification water treatment process is based on the injection of a natural product called marine biopolymer into the seawater circuit. This solution limits organic and mineral deposits in the pipes (biofouling) while significantly reducing the use of chlorine (by up to 90% depending on the season), and therefore its impact on the quality of the water discharged. This process offers a number of other environmental benefits: a 100% biodegradable biopolymer digested by the marine environment, no ecotoxicity (BIOCIDE, REACH, endocrine disruptors, etc.) and lower energy consumption (400 MWh/year saved). This fully biodegradable solution is a world first and is set to be rolled out at other LNG carrier terminals in France.
Artelia was commissioned by Elengy to design and build an injection skid with a polymer chassis, including product injection pumps and storage equipment. Our teams were responsible for carrying out the civil engineering, infrastructure works (roads, networks and distribution), piping, boiler making and EIA (electricity, instrumentation and automation), and then commissioning the facilities.
