Abstract

The invention provides an air stripping oil refining process taking nitrogen as a gas source, and relates to the technical field of petroleum refining. The air stripping method oil refining process taking the nitrogen as the gas source comprises the following steps that a liquid ring vacuum compressor matched with a petroleum refining device is determined according to the load of the petroleum refining device; and nitrogen serves as a gas source and is fed into the tower bottom of the petroleum refining device through the liquid ring vacuum compressor, a gaseous mixture discharged from the tower top after reaction is cooled through a water cooler and enters the liquid ring vacuum compressor again, and recyclable nitrogen is obtained after the gaseous mixture is subjected to adsorption treatment through lubricating oil of the liquid ring vacuum compressor. According to the technical scheme provided by the invention, a stripping-method oil refining process taking nitrogen as a gas source is adopted to replace a stripping-method oil refining process taking steam as a gas source, so that the gas source cost is greatly reduced, no oily sewage is discharged in the whole process, and cyclic utilization of nitrogen is realized.

Description

technical field [0001] The invention relates to the technical field of petroleum refining, in particular to a stripping oil refining process using nitrogen as a gas source. Background technique [0002] In the field of petroleum refining, steam is generally used as the gas source, and steam stripping is used to reduce the partial pressure of oil and gas to remove some low molecular compounds. However, the use of steam for stripping has some defects. On the one hand, the cost of using steam is high and the energy consumption is large; Increased processing cost again. Contents of the invention [0003] The main purpose of the present invention is to provide a stripping oil refining process using nitrogen as a gas source, aiming to solve the technical problems of high cost and difficult treatment of oily sewage in the current traditional steam stripping method for oil separation. [0004] In order to achieve the above object, the present invention proposes a kind of strippi...
