Utilized in the removal of high concentrations of acid gases such as carbon dioxide (CO2), hydrogen sulfide (H2S) and carbonyl sulfide (COS) OASE® techno logies have proven their versa tility and reliability in natural gas applications. BASF‘s solutions portfolio ranges from selective removal of sulfur components for sales gas (OASE® yellow) to deep removal of acid gases for LNG applications (OASE® purple). 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.
For the removal of trace amounts of H2S and CO2 BASF offers a range of Molecular Sieve adsorbents (i.e. 5A and 13X inclusive COS formation minimizing grades) that are employed in fixed bed adsorbers which are thermally regenerated.
The chemical absorption of acid gases: the highly efficient process provides a high level of gas purity and product gas recovery while keeping solvent losses to a minimum. Under the OASE brand, BASF provides customized, high-performance gas treatment technologies.
