TH9806EX - Vacuum distillation process - Google Patents

Abstract

The vacuum distillation process consists of Fluid delivery at Enter which contains liquid hydrocarbons and vapor hydrocarbons into the import section (3) of the distillation column. (1) being operated with a pressure lower than atmospheric pressure, remove the liquid from the bottom (6) section of the distillation column. (1) Let the vapor pass through three condensation lines (13b, 13a and 13) arranged above each other in the distillation column. (1) Between the import section (3) and the upper part (8), remove the vapor from the top section (8), spray the treated liquid. The cooled liquid is then entered into each condensation section (13, 13a and 13b) and the liquid is removed from each part of the condensation section (13,13a and 13b). Filled into each part of the condensation section (13, 13a and 13b) consists of the liquid removed from that condensation (13, 13a and 13b), and here the treated liquid The cold, which is injected into the condensation, the top level (13) also contains liquid. Taken from the condensation section (13a, 13b) located under the condensation section On the top as well

Claims (1)

1. The vacuum distillation process includes Conduction of a fed fluid containing hydrocarbons at temperatures in the range of 320 to 425 ° C, where the fluid contains liquids. And vapor into the input portion of the distillation column operating at lower pressure pressures Atmosphere in the range from 650 to 5200 pa, liquid removal from the bottom of the distillation column, allowing vapor to move through at least the condensation.
