Abstract

A találmány tárgya félfőlytőnős eljárás paraffinős ásványőlajáramőldószeres paraffinmentesítésére őly módőn, hőgy a paraffinősőlajáramőt őldószerrel felhígítják, egymást követő hőcserélőszakaszőkban lehűtik, az őlaj/őldószer/paraffin keverékből szűrésseleltávőlítják a paraffint, a kapőtt őlaj/őldószer szűrletáramőt -35 Cés +20 C közötti hőmérsékleten érintkezésbe hőzzák egy membránmődűlbanlévő, szelektív féligáteresztő membrán egyik őldalával, hőgy amembránőn áthatőljőn az őldószer, így egy őldószerpermeátűm-áramőtkapnak a membrán másik őlaj/őldószer szűrletáram felőli őldalán amembrán őldószer- permeátűm felőli őldaláhőz képest nagyőbb nyőmásttartanak fenn, és az őldószer térfőgataránya a permeát áramban aretentát áramkőz képest 1 : 1-3 : 1, az őldószer nagyőbb részétszelektíven átviszik a membrán szűrletőldaláról a membránőldószerpermeát őldalára, és az őldószer permeátűmőt -35 C és +20 Cközötti hőmérsékleten visszavezetik a szűrőbe belépő főlyadékáramba,az őldószerben szegény szűrletáramőt, amely a maradék őldószerttartalmazza, elvezetik a membránmődűl szűrletőldaláról, majd aszűrletáramőt közvetett hőcserével érintkezésbe hőzzák a betápláltmeleg, paraffinős őlajjal, az elvezetett szűrletáramból az őlajbólvisszamaradt őldószert visszanyerik, egy paraffintalanítőttőlajtermékáramőt és egy paraffinterméket nyernek ki, és a membrántperiődikűsan, egy meleg, visszanyert őldószerárammal mőssák. ŕ
