Problems solved by technology

[0008] 1) It is not conducive to the effective utilization of condensate oil resources;
[0009] 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;
[0010] 3) Blending makes the production device unable to play its original production function, which brings unstable and unsafe factors to production
However, the compressor system has disadvantages such as high investment, complex system, high operation and maintenance costs, etc.

Abstract

The invention discloses a system and a method for processing condensate oil. The system comprises a primary tower and an atmospheric tower; the bottom of the primary tower is provided with a primary tower reboiler; and the bottom of the atmospheric tower is provided with an atmospheric tower reboiler. The method comprises the following steps of: heating one part of primary tower bottom oil by using the primary tower reboiler, returning the heated oil to the primary tower bottom, heating the other part of primary tower bottom oil by using an atmospheric heating furnace; and heating one part of atmospheric tower bottom oil by using the atmospheric tower reboiler, returning the heated oil to the atmospheric tower bottom, and discharging the other part of atmospheric tower bottom oil, which serves as a heavy oil product. The system and the method can overcome a processing difficulty that light hydrocarbon content is high in the condensate oil processing process, are suitable for a production device which does not have a requirement for recycling a liquefied gas product in the condensate oil, and have the advantages of simple operation and low energy consumption.

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 of oil and gas fields and different mining methods, the by-products in the process of exploitation of condensate oil and gas fields have different compositions. However, there is one basic common point among different condensate oils, that is, the content of light components is high. 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. [0004...
