Problems solved by technology

However, crude white oil has extremely high requirements on product color number, sulfur content, nitrogen content, kinematic viscosity, flash point and other properties, especially color number. The prior art usually uses petroleum distillate hydrogenation to produce crude white oil products, and the above-mentioned The process of producing diesel products by hydrogenation upgrading method is difficult to be applied in the production of crude white oil products due to the problem that aromatics make the product dark.

Abstract

Disclosed is a production method of a crude white oil product. The production method includes the following steps: a) mixing raw oil and hydrogen, heating the mixture of the raw oil and the hydrogen to 300 DEG C-320 DEG C, putting the mixture into a first reactor for a hydrotreating reaction, and controlling the temperature to rise 30 DEG C-60 DEG C to obtain a refined reaction product, wherein the raw oil is composed of an atmospheric pressure fraction and a coking diesel oil fraction having a mass ratio of (1-6):4; b) putting the refined reaction product obtained by the step a) into a secondreactor for a diesel oil modification reaction, and controlling the temperature to rise 5 DEG C-20 DEG C to obtain a modified reaction product; and c) carrying out gas-liquid separation on the modified reaction product obtain by the step b), desulfurizing obtained gas and recycled, and fractionating obtained liquid to obtain naphtha and the crude white oil. The production method uses the raw oilof the specific components and combines with specific conditions and parameters to achieve better interaction so as to produce the crude white oil product with color number, sulfur content, nitrogen content, kinematic viscosity and flash point satisfying requirements of indicators by using a hydro-upgrading method.

Description

technical field [0001] The invention relates to the technical field of petroleum refining and processing, more specifically, relates to a production method of a crude white oil product. Background technique [0002] Hydrogenation process is an important processing technology commonly used by petroleum refining and processing enterprises to remove or transform non-ideal components in raw materials and produce high-quality products that meet corresponding specifications. For example, in the prior art, the hydrogenation upgrading method is used to produce high-density diesel products. This process uses catalytic diesel, coked diesel and atmospheric diesel as raw materials, and undergoes hydrogenation reaction in the reactor to obtain high-density diesel. Finished product, naphtha is obtained at the same time. However, the high specific gravity diesel product produced by this process still contains a small amount of aromatics, which makes the product darker and has poor product...
