Method of treating hydrocarbon oils
Patent
·
OSTI ID:7280461
In the process of refining petroleum oil containing paraffin wax the oil is mixed with liquefied hydrocarbon gases having a vapor pressure greater than atmospheric at ordinary atmospheric temperature. The mixture is cooled to a temperature sufficient to congeal the wax content, and the cooled mixture is treated with sulphuric acid. The cooled acid treated mixture is passed through a settling tank to thereby separate acid reaction products and high melting wax from the oil mixture by settling, and the oil mixture is passed from the settling tank to separating the remaining portion of the wax from the oil mixture.
