Honeywell UOP Separex system to be used for offshore gas purification plant
Honeywell UOP announced that PETRONAS Carigali Sdn. Bhd. (PCSB), a subsidiary of PETRONAS, will use UOP’s modular natural gas processing technology in the development of a 900 million standard cubic feet per day (mmscfd) offshore gas purification plant in the Kasawari gas field located in the South China Sea, offshore Sarawak in Malaysia. The Kasawari gas field was discovered by PETRONAS in 2011.
UOP’s acid gas removal technology, which includes UOP’s MemGuard™ and Separex™ technologies and adsorbents to remove contaminants such as carbon dioxide, hydrogen sulfide and mercury from natural gas, will be used at the facility. Once built, it will rank among the largest offshore gas treatment systems in the world. These systems are ideal for remote locations and offshore locations, reducing costs with faster delivery and start-up and with increased efficiency in the bulk removal of contaminants.
“With its smaller footprint, weight and increased reliability and efficiency in removing contaminants, our modular Separex technology is especially suited to process natural gas for production and power generation in remote locations such as the Kasawari offshore field,” said Michael Cleveland, Vice President and General Manager of UOP’s Gas Processing business. “This frees up valuable space within the subsea pipelines that bring the gas from offshore to onshore and reduce moving parts which require minimum operator intervention.”
The gas processed at Kasawari will be further processed and liquefied at the existing Malaysia LNG complex (MLNG), to be exported globally for power generation. The elements of the membrane system will be produced in UOP’s Separex Membrane Manufacturing center in Penang, Malaysia.
UOP Separex membrane systems contain spiral wound membrane elements that remove acid gas and vapour phase water from natural gas streams. Decades of operation in natural gas service demonstrate that Separex membranes are the most durable type of membrane in the industry. To date, more than 130 Separex systems have been installed worldwide.
PETRONAS is an integrated global LNG producer with more than 37 years of experience, and more than 11,000 LNG cargoes safely delivered from its global portfolio of facilities in Malaysia, Australia, Egypt and in the future, Canada.
Corrosion Control for Gas Treating Amines: Technology Leads to Increased Amine Unit Efficiency
Accelerated basin drilling activities combined with increased fugitive gas emission capture technologies have increased trace oxygen levels in midstream natural gas. Oxygen present in concentrations even as low 30-50 ppm will cause costly corrosion-related problems in plant operations and processing equipment. One area in the plant most affected by oxygen is the amine unit. Oxygen will degrade MDEA-blended amines to corrosive amino acids and heat-stable amine salts.
Learn how a new technology from BASF combined with innovation from Nalco Water can increase amine efficiency and reduce costs associated with corrosion. This new technology will inhibit the degradation of amines from oxygen attack and control corrosion in process gas, while stabilizing the amine from degradation into bicine and other heat-stable amine salts. Together with Nalco Water’s real-time amine corrosion control program, have been proven to both mitigate oxygen degradation of amine and reduce the overall corrosivity of amine units.
