Optimization method of oil refinery hydrogen system and application thereof

Abstract

The invention relates to an optimization method of an oil refinery hydrogen system. According to the system provided by the invention, the maximum benefit of the oil refinery hydrogen system is targeted, constraint conditions are optimized, and a new mathematical programming algorithm including light dydrocarbon resource optimization is formed; and compared with the mathematical programming algorithm of an existing hydrogen system, the optimization method is more suitable to actual circumstances, and more benefits can be obtained to meet the requirements of hydrogen conservation and synergy for oil refinery. The invention further provides application of the method in the optimization of the oil refinery hydrogen system, and after the method is optimized, efficient utilization of hydrogen and light dydrocarbon can be realized, so that considerable comprehensive benefit is obtained.

Description

technical field

[0001] The invention relates to a method for optimizing hydrogen resources, in particular to a method for optimizing a hydrogen system in an oil refinery. Background technique

[0002] In order to meet the requirements of inferior crude oil, product quality upgrade, and clean production, the processing capacity of catalytic hydrogenation units in oil refineries is increasing, and the operating severity is increasing. The demand for hydrogen is increasing. Hydrogen has become the only raw material cost in oil refineries. The second largest cost element after crude oil cost. Adding a hydrogen production device not only has high investment costs and high operating costs, but also consumes energy and pollutes the environment, which does not meet the requirements of energy conservation and environmental protection. Therefore, how to develop low-cost hydrogen to meet production needs and reduce hydrogen costs has become a topic of great concern to refiners. Impro...
