Process for improving absorption stability in petroleum refining process

Abstract

The invention discloses a process based on improving absorption stability in the petroleum refining process, comprising the following steps: compressed rich gas cooling process, absorption process, reabsorption process, desorption process, gasoline stabilization process, and light and heavy gasoline separation process. This process can efficiently absorb the fractionated components, avoid the reaction caused by contact with each other, make the components stable and convenient for subsequent use, and solve the unreasonable design of the absorption process for the fractionated components in the existing refining process. The absorption effect is poor, and it is extremely unstable, which can easily lead to reactions between components, resulting in the problem of composition confusion.

Description

technical field [0001] The invention belongs to the petroleum field, and in particular relates to a technology based on improving absorption stability in the petroleum refining process. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. It is composed of a mixture of different hydrocarbons, and its main component is alkanes. In addition, petroleum also contains elements such as sulfur, oxygen, nitrogen, phosphorus, and vanadium. Petroleum is mainly used as fuel oil and gasoline, which constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. Oil is mostly hydrocarbons. It is composed of a mixture of different hydrocarbons. The chemical elements that make up petroleum are mainly carbon (83% ~ 87%), hydrogen (11% ~...
