Seawater Electrochlorination System for LNG regasification facility

Severn Trent De Nora, Fort Washington, will provide its SEACLOR® seawater electrochlorination system to control biofouling at a liquefied natural gas (LNG) regasification facility developed by Petronas Gas Berhad in Sungai Udang, Melaka, Malaysia.

The new facility, which is designed to import LNG, store it at floating storage units and then vaporize it at the regasification unit, is scheduled for completion in mid-2012. The contract for the 71-kg/h SEACLOR system was awarded by Sapura Energy Ventures Sdn Bhd of Malaysia.

During the liquefaction and regasification process, chlorinated seawater is used for cooling or heating in order to control biofouling. Sodium hypochlorite, generated onsite, is an excellent chlorine equivalent for this biofouling control application.
