Veolia delivers water treatment unit

Published by
Oilfield Technology,

Veolia’s MPPE® unit will be used to treat the gas/condensate produced water stream on the Ichthys LNG project’s floating production storage and offloading facility (FPSO). The MPPE unit will remove dissolved and dispersed toxic constituents like aromatic (BTEX), polyaromatic hydrocarbons (PAHs) and oil, resulting in a zero harmful discharge (ZHD) to the environment.

The ± 450 ton MPPE module unit (19.1 x 16.5 x 18.2 m), containing two parallel MPPE units, has been successfully loaded to Korea and placed on the FPSO.

The INPEX-operated Ichthys LNG Project will involve offshore preliminary processing of gas from the Ichthys field to remove water and extract condensate before being transported to onshore LNG processing facilities in Darwin via an 890 km pipeline. Most condensate will be sent to an in-field FPSO from which it will be shipped to market. The Ichthys LNG Project is expected to produce up to 8.9 million t of LNG and 1.6 million tpy of LPG, along with approximately 100 000 bpd of condensate at peak.

During the production of gas and condensate, formation and dehydration water is co-produced containing toxic dissolved and dispersed aromatics, aliphatics and polyaromatic hydrocarbons. The MPPE technology is able to remove all of these toxic compounds securely, and in a single process, to comply with the strictest requirements for ZHD. The two fully automated MPPE units are delivered in one module.

The MPPE unit was designed and built following the highest offshore standards and is designed for an operational lifetime of 40 years. It fulfills the present and future health, safety, environmental and ergonomic requirements.

“We are very proud to deliver this high tech water treatment system to help INPEX achieve their ambitious goals”, said Erik Middelhoek, Managing Director of Veolia MPP Systems. “It was a challenging project with a fantastic end result”.
