Description

Znany jest sposób pozbawiania suro¬ wych olejów suhstancyj asfaltowych przez traktowanie ich benzyna normalna albo skroploinemi weglowodorami, otrzymanemi z gazów ziemnych, jak pentanami, butana¬ mi i ich mieszaninami. Jednakze oddziele¬ nie od zywic i podobnych zanieczyszczen nastepuje przytem naogól tylko w nie¬ znacznym stopniu.Obecnie stwierdzono, iz mozna z naj¬ rozmaitszych produktów, zawierajacych o- leje, wydzielic czyste oleje wysokowrza- ce, calkowicie pozbawione takich zanie¬ czyszczen, jak asfalty i zywice, twarda i miekka parafina, jesli produkty te po¬ traktuje sie, najlepiej pod cisnieniem, skroplonym metanem, etanem lub propa¬ nem albo mieszanina wszystkich tych we¬ glowodorów, w szczególnosci mieszanina metanu z etanem lub' z propanem albo eta¬ nu z propanem. Jako produkty, zawierajace oleje, które mozna przerabiac sposobem wedlug wynalazku, wchodza w gre wszel¬ kiego rodzaju pozostalosci po destylacji lub krakingu olejów mineralnych, dalej najrozmaitsze mazie, smoly, oleje smarowe oraz produkty uwodorniania wegla i ole¬ jów.Zaznaczyc przytem nalezy, ze rzecza istotna przy stosowaniu wynalazku jest to, aby ciecz ze skroplonych weglowodorów skladala sie w wiekszosci z metanu, etanu lub propanu, lub tez z mieszanin tych ga¬ zów, które zawieraja pewne ilosci domie-tóefc:wai\^ói<^róyl p podwój nem wiesza¬ niu, np. etylenu, propylenu, butylenu. ..,., Produkty^wyjsciowe mozna pod4ac1It is known to de-asphalt crude oils by treating them with normal gasoline or with liquefied hydrocarbons, obtained from natural gases, such as pentanes, butanes, and mixtures thereof. However, the separation from the resins and similar impurities is generally only to a minor extent. It has now been found that it is possible to separate pure high-boiling oils from a wide variety of oily products, completely free of such impurities as asphalts and resins, hard and soft paraffin, if these products are treated, preferably under pressure, with liquefied methane, ethane or propane, or a mixture of all these hydrocarbons, in particular a mixture of methane and ethane or with propane or ethane nu with propane. As products containing oils that can be processed according to the invention, they include all kinds of residues from the distillation or cracking of mineral oils, and also the most diverse greases, tar, lubricating oils and products for the hydrogenation of coal and oils. It is essential for the application of the invention that the liquid of liquefied hydrocarbons consists mostly of methane, ethane or propane, or mixtures of these gases which contain some admixtures: suspension of, for example, ethylene, propylene, butylene. ..,., Output products can be specified
