OASE^® yellow for Selective Treatment

Developed to enable selective removal of sulfur components from natural gas as well as acid-gas enrichment (AGE) or tail-gas treatment (TGT) units, BASF's OASE^® yellow technologies offer a range of solutions that meet our customer's specific project requirements.

There are five spherical tanks in the Friesenheim Island section of BASF’s Verbund site in Ludwigshafen which supply the production facilities with feedstocks. The tanks have a combined total capacity of around 7.5 million liters of liquefied gas. They are used to store butane gas.

OASE^® green for Biogas

The OASE^®green technology is primarily targeted for biogas applications. It is characterized by an exceptionally robust performance on gas streams containing oxygen and/or olefins.

Steam cracker II, the largest individual plant at BASF's Ludwigshafen site, covers a surface area of about 64,000 square meters, which is about the size of 13 soccer fields. The steam cracker is also the heart of BASF's Verbund production strategy. This giant plant has been operating since 1981 and uses steam to crack naphtha at about 850°C [1,562°F]. This process leads primarily to ethylene and propylene, both indispensable feedstocks for manufacturing numerous products in Ludwigshafen.

HiPACT^®

In partnership with JGC, BASF has developed a unique high-pressure gas treatment technology for high-pressure regeneration to allow for energy-efficient carbon capture and storage (CCS) applications, which is marketed under the HiPACT^® brand.

OASE^® sulfexx™ for Selective Treatment

OASE^® sulfexx^™ is a highly energy efficient gas treating technology jointly developed by ExxonMobil and BASF, which helps refiners and gas processors to meet their sulfur removal targets while reducing carbon footprint. OASE^® sulfexx^™ provides a competitive advantage by increasing plant capacity and lowering investment and production costs.

BASF customers of the gas treatment business area can use the innovative, globally unique digital platform OASE® connect (photo) to design the operation of their plants more efficiently.

Reducing CO₂ in the maritime industry with OASE^®

International shipping is to become climate-neutral by 2050. Various technologies are being pursued to achieve this ambitious goal. One of these is carbon capture and storage on board. Gas treatment technology is one of the most advanced processes for separating carbon dioxide from gas streams. In order to remove the carbon dioxide produced from the engine exhaust gases, the most efficient gas treatment possible is essential. BASF has developed solutions for the purification of natural gas from great depths and the high seas (FLNG) as well as for the treatment of exhaust gas streams from power stations or industrial plants.
