Description
Problem taniego rafinowania weglowo¬ dorów alifatycznych i aromatycznych nie zostal dotychczas zadowalniajaco rozwiaza¬ ny. Powstajace przy myciu kwasem siarko¬ wym zywice sa zródlem duzych strat w we¬ glowodorach. Straty te sa spowodowane miejscowem sulfonowaniem i spalaniem we¬ glowodorów wskutek zetkniecia sie ich z nadmiarem kwasu siarkowego, dzialajacego na malej powierzchni. Przy dodawaniu kwasu w postaci rozdrobnionej i przy do¬ brem mieszaniu weglowodory nie sulfonu¬ ja sie i nie spalaja. Niniejszy wynalazek po¬ zwala na zmniejszenie potrzebnej ilosci kwasu do 25%, przy jednoczesnem zmniej¬ szeniu wytworzonych zywic do 40%. Przed rafinowaniem weglowodory o róznym cieza¬ rze wlasciwym miesza sie w takim stosunku, by temperatura, jako wynik reakcyj polime¬ ryzacyjnych mycia, nie przekraczala pod normalnem cisnieniem 80°C.Przyklad. Na 1000 cz. mieszanki, skladajacej sie z 70 cz. benzenu, 10 cz. to¬ luenu oraz 20 cz. ksylenu i solwentnafty, do-daje sie kwats siarkowy w postaci deszczu, wsród mieszalnia mieszanki. Wytworzone zywice wynosza 1.5—2%. PLThe problem of cheap refining of aliphatic and aromatic hydrocarbons has so far not been satisfactorily solved. The resins formed during washing with sulfuric acid are a source of high losses in hydrocarbons. These losses are due to the local sulfonation and combustion of the hydrocarbons due to their contact with an excess of sulfuric acid acting on a small surface. When the acid is added in fine form and with good agitation, the hydrocarbons do not sulfonate and do not burn. The present invention makes it possible to reduce the amount of acid needed by up to 25% while reducing the resins produced by up to 40%. Prior to refining, hydrocarbons of different specific gravity are mixed in such a ratio that the temperature, as a result of the polymerization washing reactions, does not exceed 80 ° C. under normal pressure. For 1000 parts mixture, consisting of 70 parts benzene, 10 pts. toluene and 20 parts xylene and solvent naphtha, sulfuric acid is added in the form of rain, among the mixing of the mixture. Resins produced were 1.5-2%. PL
