Extraction of hydrocarbons from “yellow oil” with liquefied gas residue

In order to extract the hydrocarbon content obtained from “Yellow oil” by using the liquefied gas residue collected at the bottom of the gas bottles during the distribution of liquefied gas to the local population, the properties of the liquefied gas residue were analyzed by traditional methods and the chemical composition was analyzed with the help of chromatographic methods. Based on the results of the analysis, it has been proven that it can be used as an extractant due to the fact that its composition consists of a mixture of paraffin hydrocarbons. In the extraction of hydrocarbon content, when extracting abilities of hexane and liquefied gas residue were studied, it was found that separation of raffinate from the extraction mixture is carried out twice as fast in liquefied gas residue as compared to hexane. It is recommended to use it as an extractant in the extraction of hydrocarbon content.
