Improvement of energy performances in the chemical industry

Rueil-Malmaison, 27 april 2018

The second largest manufacturer of PVC (polyvinyl chloride) in Europe has appointed AIT-STEIN GROUP, via its subsidiary COMECO, to carry out the design, manufacture and delivery of two economisers that will be installed downstream of the steam generators on the site in Fos-sur-Mer.

The Fos-sur-Mer site is devoted to the production of chlorine, caustic soda and vinyl chloride monomer from salt supplied by the Vauvert site.

In order to reduce greenhouse gas emissions and to optimise energy consumption in the site’s production processes, these two economisers will produce steam from the combustion of a mix of natural gas (in line with EU legislation) and hydrogen, instead of FO2 as was originally intended in the unit.  

The economisers will be manufactured in the COMECO workshops located in Gasny (27) and will have the capacity to produce steam at 85 T/h. Delivery of the first machine is set for this summer and the second for next year.

As supplier of solutions adapted to the needs of its customers, AIT-STEIN GROUP has designed this equipment with a view to adding additional rows and thus increasing this unit’s capacity of steam production and yield.

The original equipment was also manufactured and delivered by COMECO over 20 years ago; proof of the long service life of the group’s equipment and its clients’ loyalty.
