Demineralised Water Reverse Osmosis (DMRO)
Oil and Gas
Barrow Island, Western Australia
When Chevron started commissioning its Gorgon LNG gas train on Barrow Island off the north coast of Western Australia it needed additional demineralised water (high purity water) for pressure testing pipework, boiler feed water and other cleaning activities.
Whilst this was a critical application requiring very high purity water (Electrical conductivity (EC) required of <1μS/cm at 25°C) it was only required for a relatively short period of time during commissioning and therefore it made sense to hire water treatment plants from MAK Water’s fleet of hire plants.
MAK Water’s proposed solution of a single stage Reverse Osmosis (RO) plant followed by Ion Exchange was selected as the simplest, most robust solution to provide demineralised water.
