Treatment Technology BASF, Exxon Mobil Unveil New Gas Treating Technology for Reducing Sulfur, CO2 Emissions

| Editor: Ahlam Rais

The energy-efficient amine gas treatment technology Oase sulfexx is expected to assist petroleum refiners and gas processors meet regulatory requirements of the future, reduce operating costs and increase capacity. The technology is capable of selectively removing hydrogen sulfide, while minimising co-absorption of CO2 from gas streams.

Texas/USA – BASF and Exxon Mobil Catalysts and Licensing have recently released a new highly energy efficient amine gas treatment technology named Oase sulfexx. The technology is based on a new proprietary amine-based solvent that selectively removes hydrogen sulfide (H2S), while minimising the co-absorption of carbon dioxide (CO2) from gas streams.

The companies jointly developed the amine-based solvent to help petroleum refiners and gas processors meet future requirements, while also increasing capacity and lowering operating costs on existing equipment. For new facilities, the use of this technology will reduce the size of the equipment and the initial capital investment compared to conventional amine gas treatment units.

“We are pleased to partner with BASF to develop Oase sulfexx, a compelling solution aimed at helping operators reduce emissions and lower costs,” said Dan Moore, president of Exxon Mobil Catalysts and Licensing. “Collaborating to develop new, game-changing technologies is central to how we work, and the development of this new product provides yet another example of what we bring to the marketplace.”

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

“Oase sulfexx will help our customers to achieve their sustainability goals by lowering energy consumption and reducing sulfur emissions,” said Andreas Northemann, vice president of BASF Gas Treatment. “The H2S selectivity of Oase sulfexx is outstanding – it’s hard to find a product in the market with that type of capability.”

Multiple pilot plant tests at Exxon Mobil and BASF facilities have demonstrated the superior selective properties of this solvent compared to methyldiethanolamine (MDEA) formulations and Flexsorb and SE Plus solvents. A commercial demonstration concluded at a tail gas treating unit located in North America further confirms the results.

Oase sulfexx will help to debottleneck existing Claus tail gas treating, acid gas enrichment, and high-pressure acid gas removal units. In Claus tail gas treating units, the technology can achieve less than 10 ppmv H2S specifications while rejecting CO2 to meet future emission requirements.
