  • Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)

Abstract

PURPOSE: To efficiently obtain as a bottom fraction a fraction effective as the raw material for a petroleum resin, by circulating a high-boiling petroleum fraction flowing down to the bottom of a distillation column to a vaporization zone and keeping an overflow fraction at a temp. below that of the overflow zone.
CONSTITUTION: A liquid for distillation supplied via line 1 is fractionated by tray 2 and a high-boiling fraction is stored in overflow zone 11 provided above the bottom of the column. Fraction 13 in the overflow zone 11 is heated in order to be kept at its distillation temp. by being for the most part circulated into vaporizer 4, in which it is partially vaporized to contribute to distillation as a vapor load to the column, and the balance of the overflow fraction is overflowed pref. via overflow conduit 14 to the bottom of the overflow zone. The temp. of bottom fraction 16 is kept at a temp. below that of the overflow zone by cooler 6, resulting in prevention of the thermal polymn. of the fraction.
