Method Of Separating A Predetermined Fraction From Petroleum Oil Using Multistage Evaporators
US Patent:
4131538, Dec 26, 1978
Filed:
Oct 20, 1977
Appl. No.:
5/843831
Inventors:
Charles D. Rose - Shreveport LA
Frederick W. Gilbert - Shreveport LA
Frederick W. Gilbert - Shreveport LA
Assignee:
Riley-Beaird, Inc. - Shreveport LA
International Classification:
C10G 700
US Classification:
208352
Abstract:
A method and apparatus for separating a predetermined fraction from a crude oil includes preheating the crude oil to vaporize a portion, and feeding the two-phase crude to a first stage flash evaporator. In the first stage evaporator, a vapor portion is separated from residual liquid and the residual liquid is used by means of heat exchange to preheat the crude oil. The vapor fraction from the first stage evaporator has an approximate 90% ASTM distillation temperature about 50-60. degree. F higher than the first stage evaporator temperature. The vapor fraction is condensed to form a condensate, and the condensate is conveyed to a stripping column for mass transfer with ascending vapors from a second stage boiling type evaporator. The second stage evaporator is operated at a vaporization temperature approximately equal to the 5% ASTM vaporization temperature of the predetermined petroleum fraction collected as liquid from the second stage evaporator. Vapors removed from the stripping column include a crude oil fraction having an ASTM flash temperature lower than the temperature of operation of the second stage, and crude oil volatile impurities.
