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...

AI Technical Summary

Problems solved by technology

[0010] 1) It is not conducive to the effective utilization of condensate oil resources;

[0011] 2) Separate storage and blending facilities must be installed, but the volatility of condensate oil causes excessive loss and has a great impact on safety and environmental protection;

[0012] 3) Blending makes the production device unable to play its original production function, which brings unstable and unsafe factors to production

[0014] Due to the low content of heavy components in the condensate oil, the vaporization rate at the outlet of the heating furnace of the distillation tower is too high, and the heating furnace is difficult to operate smoothly. At the same time, it will cause uneven distribution of gas and liquid phase loads in the distillation tower, and the gas phase load is too large. The liquid phase load is too small, resulting in too large tower diameter, making the operation of the tower difficult to control
