Gas Treatment

OASE® purple for Natural Gas

OASE® purple

Utilized in the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S), the OASE purple technology has proven its versatility and reliability in natural-gas applications. Our solutions port­folio ranges from selective removal of sulfur components for sales gas to bulk removal of acid gases for LNG applications.

Our customers appreciate this highly efficient and environmentally friendly technology for its flexibility and low capital expenditure (CAPEX). Additionally, the low energy demand of the process combined with the non-corrosive nature of the solvent keeps operating and main­tenance costs (OPEX) low. The process also provides a high level of gas purity and product gas recovery while keeping solvent losses to a minimum.


Natural gas

Sales gas

Our experience in offering a broad range of solutions allows us to tailor our designs to the needs of our customer. Our solutions portfolio ranges from bulk to selective removal. Our designs are customized to meet feed gas and product specifications while optimizing capital expenditures (CAPEX) and operating expenditures (OPEX) based on our customer’s priorities.

Liquefied natural gas (LNG)

Our extensive technical experi­ence and reference plants in this field allows BASF to offer solu­tions that meet deep CO2 removal require­ments for a wide range of feed acid gas compositions. Additionally, BASF can go beyond the acid gas removal unit (AGRU) and offer technologies such as total sulfur management systems.

LNG Tanker

Floating LNG

We adapt on-shore LNG expertise by applying our research in 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.
