Veolia to deliver MPPE water purification unit for Shell floating LNG plant
Samsung, as part of the Technip Samsung Consortium (TSC) has placed orders with VWS MPP Systems, a subsidiary of Veolia Water Solutions & Technologies, to supply a Macro Porous Polymer Extraction (MPPE) water purification unit for Shell's Prelude Floating Liquefied Natural Gas (FLNG) project.
Under the contract, VWS MPP Systems will deliver the MPPE water purification technology to treat the water produced from Shell's FLNG project in Australia.
To meet discharge limits, the MPPE water treatment technology will reduce organic concentrations in contaminated water from thousands of ppm to low ppb levels.
The fully-automated and remote-controlled MPPE technology will eliminate hydrocarbons from water by means of extraction using a Macro Porous Polymer (MPP) bed.
During the initial process, hydrocarbon-contaminated water passes through a column packed with MPPE particles, porous polymer beads that contain a specific extraction liquid.
The immobilised extraction liquid removes the hydrocarbons, which have a high affinity for the extraction liquid, from the water.
The water, co-produced during the production of natural gas formation and dehydration, contains dissolved and dispersed aromatic, aliphatic and polyaromatic hydrocarbons.
The purified water will enable Shell to achieve its environmental objective to go for zero discharge of harmful substances into the environment.
