PROCESS FOR DESULPHURING LIQUID FRACTIONS OF C3 + C4 HYDROCARBONS FROM CATALYTIC CRACKING GASES

摘要

the fracţiinii desulphurisation liquid hydrocarbons c + c4din consists of separating gases by catalytic cracking, splitting, in a fraction of a fraction of liquid from liquid cand cafter the liquid fraction of cse in propene and propane further split, after which only propene is treated with solution of sodium hydroxide, monoethanolamine,in douăcoloane successive extraction of hydrogen sulphide and carbon oxisulfurii, at which the flow of flow of propene reverses periodicallydepending on the degree of exhaustion of solutions of two columns, and the fraction c, global or separate fractions 1 and 2 c, is treated with the solution of sodium hydroxide.process for removing mercaptanilor through merox.in this way, the final propenei desulphurisation and fractions 1 and 2 of cvor be higher dimensions machinery of desulphurisation, smaller, and the consumption of utilities, diminished.
