UOP technology to remove acid gases for Petronas floating LNG in Malaysia

Honeywell's UOP has been selected by Malaysia’s Petronas to provide technology for acid gas removal on the world’s first floating liquefied natural gas (FLNG) project known as PFLNG 1, the companies said on Tuesday.

The PFLNG 1 facility, designed to extract natural gas from offshore wells and liquefy and store it for later transport, will use UOP's Amine Guard FS process to remove carbon dioxide and hydrogen sulfide from the liquefied natural gas (LNG) feed streams.

“We are pleased to continue to grow UOP's long-standing relationship with Petronas and for the opportunity to work with the company on its historic first floating LNG project,” said Rebecca Liebert, vice president and general manager for UOP's gas processing and hydrogen business unit.

“UOP offers a full suite of leading-edge, agile gas processing technologies, enabling us to design solutions for customers monetizing their gas resources," she added. "Together with Petronas, we are excited to bring continued improvements to meet the world’s growing demand for cleaner-burning and versatile natural gas energy in this new frontier of gas conditioning and treating.”

Scheduled for start-up by the end of 2015, the FLNG unit will be moored approximately 112 miles off the coast of Sarawak, Malaysia, and is designed to produce 1.2 million tpy of LNG.

The Amine Guard FS process was developed to reduce acid gas contaminants to very low levels prior to liquefaction. The technology is used to precondition the gas that results in 40% of the world’s LNG production from onshore base-load LNG plants, according to UOP officials.

UOP’s technology has been modified for use in a floating service environment to minimize plot size, weight and cost, while improving reliability, resistance to rocking motion and expanding the operating envelope.

The acid gas removal system was designed in cooperation between Petronas and UOP to obtain an optimized process capable of expansion and handling various feed stream contaminant concentrations.
