Abstract
Метод за отделяне на киселини от течни въглеводородни фракции, съгласно който въглеводородната фракция се смесва с воден разтвор на основа, сместа се довежад в допир с твърд агент за взаимодействие с цел да се постигне физично и химично модифициране на въглеводородната фракция, която след това се отделя от водната фаза, характеризиращ се с това, че течната въглеводородна фракция съдържа меркаптокиселини и нафтенови киселини, които се отделят, за да се получи въглеводороден продукт с намалено съдържание на киселина, като киселата въглеводородна фракция се смесва с малък стехиометричен излишък от водна натриева основа или калиева основа и се довежда в допир с хидрофилен гранулиран твърд коагулиращ агент преди разделянето на водната и въглеводородна фаза. Патентните претенции са формулирани в 10 точки.A method for separating acids from liquid hydrocarbon fractions, according to which the hydrocarbon fraction is mixed with an aqueous base solution, the mixture is brought into contact with a solid reaction agent in order to achieve physical and chemical modification of the hydrocarbon fraction, which is then separated from the aqueous phase, characterized in that the liquid hydrocarbon fraction contains mercaptic acids and naphthenic acids which are separated to give a hydrocarbon product with reduced acid content, the acidic hydrocarbon fraction being mixed with a small stoichiometric excess of aqueous sodium hydroxide or potassium base and brought into contact with a hydrophilic granular solid coagulating agent prior to separation of the aqueous and hydrocarbon phases. The patent claims are formulated in 10 points.
