第4题
砜胺法（Sulfinol）——混合溶剂吸收法 Sulfinol - mixed solvent absorption method（）
A、吸收剂——环丁砜和二异丙醇胺水溶液。与MEA法工艺流程相似。Absorbents - sulfoxide and diisopropanolamine solution. Similar to MEA process.
B、兼有化学吸收和物理吸收两种性能的混合溶剂。胺采用二异丙醇胺，对酸性气为化学吸收；砜采用环丁砜，对酸性气为物理吸收。A mixed solvent with both chemical and physical absorption properties. The amine USES diisopropanolamine, which is chemically absorbed by acid gas. Sulfoxide adopts sulfoxide, which is physically absorbed by acidic gas.
C、当气体中酸性气分压低时，主要为化学吸收，随酸性气分压提高，物理吸收加强。根据酸性气分压的不同，配制胺、砜和水比例不同的吸收剂，相当于把醇胺溶液中的水换为砜。由于环丁砜对酸性气吸收能力很强（远高于水），故其吸收能力远较其它吸收方法强。When the acid gas fraction in the gas is reduced, it is mainly chemical absorption, with the increase of acid gas partial pressure, physical absorption is strengthened. According to the different acidic gas partial pressure, the preparation of amine, sulfone and water ratio of different absorbent, equivalent to the alcohol amine solution of water for sulfone. Because sulfoxide has a strong absorption ability to acid gas (much higher than water), its absorption ability is much stronger than other absorption methods.
