The latest Floating Liquefied Natural Gas (FLNG) project of the Malaysian oil and gas company PETRONAS (PFLNG DUA) has selected BASF’s OASE purple for its Acid Gas Removal Unit process.

This is the first FLNG reference worldwide for BASF’s OASE Gas Treatment technology. Together with PETRONAS and the Japanese engineering partner JGC Corporation, PFLNG DUA has been successfully started up in February 2021 and completed its Performance Test Run in May 2021. The floating LNG facility opens a new source of supply for cleaner energy as it is designed to extract natural gas from deepwater gas reservoirs in depths up to 1,500 meters.

OASE purple is an amine-based solution that is utilized for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas. The removal of acid gases is necessary to prepare the gas for the liquefaction and subsequent pipeline transportation.

The highly efficient and environmentally friendly BASF-technology provides flexibility and low capital expenditure (CAPEX) for its customers.

Andreas Northemann, Head of BASF’s Gas Treatment business, says: “We are proud to now have our first FLNG reference in operation and running at 100 percent capacity, which is the fruit of many years of research. We applied our on-shore LNG expertise and conducted motion studies and Computational Fluid Dynamics (CFD) to ensure a high reliability, low maintenance design which meets our customer’s stringent off-shore specifications and challenges.”
