Problems solved by technology

Due to the different experience of operators, experienced operators can adjust efficiently and smoothly, while some operators take a long time to operate and have large fluctuations in working conditions
This lack of effective adjustment rules for operating parameters makes the dynamic adjustment process consume time, waste resources, and reduce production efficiency

Abstract

The invention provides an active dynamic regulation method in a hydrocracking process. The method comprises regulating the hydrocracking process caused by inlet flow change to an objective operation state by means of a decision operation table based on hydrocracking process operation data. The active dynamic regulation method can realize high-efficiency stable regulation of a hydrocracking flow from a to-be-regulated state to an anticipated state and effectively prevents problems such as long transition time, large working condition fluctuation and severe resource wastage caused by regulation according to man experience.

Description

technical field [0001] The invention relates to the technical field of dynamic adjustment in chemical processes, and more specifically relates to an active dynamic adjustment method in a hydrocracking process. Background technique [0002] The oil refining industry is located in the upstream of the manufacturing industry, and its output value accounts for about one-third of the national economy. It is a pillar industry of the national economy and a major driving force for the development of other industries. With the rapid economic development, China's demand for and dependence on energy is increasing day by day. In the 21st century, China's oil energy consumption accounts for nearly 30% of the overall energy consumption. Oil refining has become the core of the national economic security strategy. In the secondary processing technology of crude oil, hydrocracking technology has the characteristics of strong adaptability of raw materials, high flexibility of production operat...
