Problems solved by technology

Among them, the most critical problem is that in the existing delayed coking method, a large amount of coke and low-value dry gas will be produced in the coke tower coking process, and the total liquid yield (light fuel oil products account for 1% of heavy oil raw materials) percentage) is only 72% to 75%, and the yield is low, which makes the utilization rate of petroleum resources low

Abstract

Provided are a heavy oil processing technology and a processing apparatus. The processing technology comprises the following steps: A) under air isolation conditions, performing a dry distillation reaction between the heavy oil and a catalyst under the condition of stirring, to obtain a high-temperature oil gas; and B) successively performing condensation and separation of the high-temperature oil gas obtained in step A), to obtain a light fuel oil. The heavy oil processing apparatus comprises a reactor (6), a condenser (10) and a separator (12). In the present technology, by stirring, the rate of occurrence of foaming is reduced, the evaporation area of drops of liquid is increased so that the gasifying content of the heavy oil during movement is increased greatly, the amount of coke generated during the preparation of a light oil from a heavy oil is reduced, and the liquid yield in the heavy oil processing is improved.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a heavy oil processing technology and processing device. Background technique [0002] Heavy oil refers to crude oil with high bitumen and colloid content and high viscosity. Due to its high density and high underground viscosity, it is also called heavy oil. With the decrease of conventional oil, the inferior and heavy quality of crude oil has become a global trend. According to incomplete statistics, the technically recoverable resources of heavy oil in the world amount to 65 billion tons. Therefore, the processing technology for lightening heavy oil has gradually become the focus of scientific research. [0003] At present, the processing technology of heavy oil lightening mainly includes thermal cracking, visbreaking and delayed coking. The thermal cracking process uses vacuum diesel oil as raw material, which has been eliminated now; visbreaking ...
