System and method for processing condensate oil

Abstract

The invention discloses a system and a method for processing condensate oil. The system comprises that: a vacuum distillation tower is arranged on the rear of a normal pressure distillation tower, the bottom of the normal pressure distillation tower or the bottom of the vacuum distillation tower is provided with a tower bottom reboiling furnace. The method comprises: transferring a part of light fractions to the vacuum distillation tower from the normal pressure distillation tower to carry out precipitation, and transferring a part of heat load in a feeding heating furnace to the tower bottom reboiling furnace. With the method of the present invention, a processing problem of low heavy component content in the condensate oil processing process in the prior art is solved. In addition, a process is simple, equipment investment is low, energy consumption is low, and operation is stable.

Description

technical field

[0001] The invention relates to the field of petrochemical industry, and more specifically, relates to a system and method for processing condensate oil. Background technique

[0002] With the rapid development of the global economy and the rapid expansion of energy demand, oil resources are increasingly tense, and various oil resources are widely exploited and utilized.

[0003] Due to the different geological properties and mining methods of oil and gas fields, the by-products in the process of exploitation of condensate oil and gas fields have different compositions. But there are two basic commonalities among different condensate oils:

[0004] 1) High content of light components. The naphtha fraction content is close to or even exceeds 50%. Most condensate oils contain C3 and C4 components (often reaching more than 5%), and some also contain C1 and C2 components. Only a few condensate oils do not contain C4 or less components;

[0005] 2) The content...
