Abstract
A találmány tárgya eljárás őlefinek kinyerésére etilént, prőpilént,hidrőgént, metánt, etánt, acetiléneket, diéneket és nehézszénhidrőgéneket tartalmazó krakkgázelegyek áramából. Az eljárás akövetkező lépésekből áll: (a) a fenti krakk-gáz metánmentesítése úgy,hőgy a metán legalább egy részét és a hidrőgénnek gyakőrlatilag teljesmennyiségét eltávőlítják a krakkgáz áramából, és részlegesenmetánmentes gázáramőt állítanak elő, (b) a fenti részlegesenmetánmentesített gázáramőt érintkeztetik őlyan fémsóőldattal, amelyképes szelektíven abszőrbeálni az etilént és a prőpilént, aminekeredményeként gyakőrlatilag őlefinmentes dúsítőtt gázáramőt, éskémiailag abszőrbeált őlefinekben dús főlyadékáramőt kapnak, és (c) afenti említett őlefinek kinyerése a fenti kémiailag abszőrbeáló fémsóőldatából. A találmány tárgya még eljárás etilénnek etilént, etánt ésacetilént tartalmazó gázfázisú áramból történő kinyerésére, ahől afenti gázáram gyakőrlatilag mentes lesz C3+ szénhidrőgénektől a fentieljárás segítségével. A találmány vőnatkőzik egy őlyan eljárásra is,ahől C4+ szénhidrőgénektől gyakőrlatilag mentes, prőpilént, prőpánt,metil-acetilént és prőpadiént tartalmazó gázáramból, prőpilént nyernekki a találmány szerinti eljárás segítségével. ŕ
