Title:
RECOVERY OF TAR ACID FROM HYDROCARBON OIL CONTAINING THE SAME
Document Type and Number:
Japanese Patent JPH01201391
Kind Code:
A
Abstract:
PURPOSE: To improve the yield of extraction, by adding an alkaline soln. to a tar acid-contg. hydrocarbon oil and conducting mixing and centrifugation to separate an alkaline tar acid soln.
CONSTITUTION: A tar acid-contg. hydrocarbon oil in a stock tank 1 and an alkaline soln. in a tank 4 are fed into a static mixer 3 from a pump 2 and a pump 5, respectively, and mixing is conducted while stirring to prepare a mixed soln. This soln. is separated with a centrifuge 6 at a centrifugal force of 6,000G or more. The acid-free hydrocarbon oil is discharged into a tank 7, while an alkaline tar acid oil is discharged into a tank 8.
