Project Description
The Offshore CPOC production platform, in the Malaysia- Thailand Joint Development Area (JDA) Block B-17, is designed to process 650 MMSCFD Inlet gas, and must reduce the CO2 from 43% inlet content to 23% sales gas content. Carigali-PTTEPI Operating Company SDN BHD (CPOC) selected NATCO Cynara® membrane technology for this important project. Cynara membranes are the industry-leading technology advanced and perfected by NATCO to deliver the highest separation recovery rates, greatest efficiency, and lowest cost solution. The membranes have the longest useful life because their robust design can handle condensing hydrocarbons in the gas stream. Cynara membranes have the largest amount of membrane surface area in each device. This efficient design translates into the smallest footprint and lowest capital cost available for the restrictive offshore environment.
Scope of Supply
NATCO provides turnkey supply of membrane technology, process design, detailed engineering, equipment fabrication and start-up supervision for the membrane and valve skids and pre-treatment equipment including separation, filtration, dehydration and hydrocarbon dewpointing. NATCO’S industry leading TEST™ Automation & Control systems provide the programmable logic to operate the system. NATCO can also provide aftermarket service and support, as well as replacement membrane elements throughout the practical life of the offshore production platform.
The project was managed between the NATCO Houston and Malaysia Scomi/NATCO execution centers as a turn-key project including local Malaysian fabrication. Membrane elements are fabricated at NATCO’s fabrication facility in Pittsburg, CA. The membrane skids will utilize eighty (80) 16” NATCO Cynara membrane elements to process the gas.
