Abstract

The research on the process of alkalization of naphthenic acids from oil distillates is reflected in the article. In the article, work was done on obtaining a stable emulsion during the alkalinization of naphthenic acids. In order to prevent the formation of the resulting emulsion, an alkalization process was carried out in the presence of sodium hydroxide. This process is carried out at a temperature of 100 ℃ and under pressure. The article mentions various methods of separation from fat fractions.

According to the presented technological scheme, first, the oil fraction is heated to a temperature of 45-55 ℃ and then to 150-170 ℃. The heated fraction is mixed with 1.2-2.5% NaOH solution. The mixture is cleaned of alkaline waste at the temperature of 120-130 ℃. The purified distillate is mixed with hot water at the temperature of 60 ℃ and sent to the precipitator. As a result, the oil distillate obtained from the precipitator is dried with hot air in a drying tank and sent to the commodity department. As a result of the extraction of alkaline waste with a binary solvent (methylethylketone: toluene), petroleum acids with a degree of purity of 95-98% are obtained.
