Can molecular sieves remove both H2S and CO2 simultaneously?
Thread Content
A natural gas purification project is currently being carried out; the purification process involves only the use of molecular sieves for desulfurization, decarburization, and dehydration, making it a much simpler process. The raw gas contains 26 mg/Nm3 of H2S and 0.5% CO2. According to available information, molecular sieves have a catalytic effect that enables H2S and CO2 to react to form COS. Will this have an impact on the molecular sieve? Can this process be used with such feed gas?
4A molecular sieve works fine; some applications see better results with 5A molecular sieve. Generally, 5A ones are more expensive. This chapter is available in the \"Natural Gas Treatment and Processing Handbook\" on the forum.
