– Zawtika Project
Group was recently awarded 2 separate contracts by SMOE for the design and
fabrication of a Produced Water Treatment Package and a Fuel Gas Package for
PTTEPI's Zawtika Project, located offshore Myanmar.
Produced Water Treatment Package contains 3 discrete treatment processes (to
remove sand and then oil, with additional upstream separator online sand
flushing) and is designed to handle a maximum capacity of 22,000 BPD.
produced water will be firstly processed via multiple Desander Hydrocyclones to
removed 99% of solids greater than 10micron, before further processing via CYCLONIXX
® Deoiler Hydrocyclone technology and IGF/DGF system to reduce the Oil-in-Water
(OIW) concentration from ~2000ppm at the inlet down to <40ppm.
the inclusion of an API-610
recirculation pump loop, the Client is also able to flush out and remove built
up sand from the upstream Separator, while production remains online. Produced
water is used as the flushing fluid and the sandy-water stream will be
processed in the Produced Water treatment package which will be designed to
allow for elevated sand levels.
package will utilise Process Group’s proprietary TUNGSTONE ® premium Desander
Cyclone range, which includes Reaction Bonded Silicon Carbide material to
provide extreme wear resistance.
Fuel Gas Package is designed to process a total of 23MMscfd of natural
gas. The process is a 2 stage process
incorporating both pressure control and providing super-heat for the fuel gas
to the compressors. This package also
incorporates filter/coalescers as well as a large scrubber vessel designed to
provide a fuel ‘buffer’ for the compressor to facilitate upset change-over.
packages are being designed and executed out of Process Group’s Singapore
office, with local fabrication in Singapore. Delivery for both
packages is scheduled for early 2013.
