PETRONAS latest floating liquefied natural gas project (PFLNG DUA) chooses to take BASF OASE? Purple technology is applied to the acid gas removal unit process. Is this also BASF OASE? Gas Treatment Technology is the world’s first floating liquefied natural gas project.
In a joint effort of BASF with PETRONAS and Japanese engineering partner JGC, the PFLNG DUA project was successfully launched in February 2021 and completed the performance test operation in May 2021. The floating liquefied natural gas facility opens up a new source of supply for clean energy, which can extract natural gas from deep-water gas reservoirs up to 1,500 meters deep.
High-efficiency gas treatment, low energy consumption
OASE®purple is an amino-based gas treatment solution specifically designed to remove acidic gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas. The removal of acid gas is a necessary step for subsequent liquefaction and pipeline transportation of natural gas.
Efficient and environmentally friendly BASF technology brings flexibility to customers and reduces capital expenditure. In addition, the process combines low energy consumption with non-corrosive solvents to keep the operation and maintenance cost low, high gas purity and high gas recovery rate of products, while reducing solvent losses to lower.
Andreas Northemann, Head of BASF Gas Treatment Operations:
We are proud to have the first floating LNG project and are running fully with the results of our many years of research. We have used our expertise in shore LNG to conduct motion and computational fluid dynamics (CFD) studies to ensure high reliability and low maintenance requirements for our clients’ rigorous offshore needs and challenges.”
PETRONAS owns and operates two floating liquefied natural gas facilities, including the PFLNG DUA project, which had previously been successfully put into operation in 2017. PETRONAS second floating liquefied natural gas facility, which is also the company’s latest project, began construction in 2015 and will be moored above the Rotan gas field with a depth of 1,300 meters.
The gas field is located 140 kilometers off the coast of Kota Kinabalu, Sabah, Malaysia, and can produce 1.5 million tons of liquefied natural gas every year.
