Abstract

The invention discloses a memory, and hydrogen resource optimization, device and equipment for a hydrogen system, and the method comprises the steps: carrying out the logic division of the hydrogen system, and building a corresponding unit model; establishing a substance mathematical model and an energy mathematical model; determining whether a feed stream of the hydrogen recovery unit can be used as a feed of the hydrogen using unit to determine whether the feed stream is used as a hydrogen supply stream or a hydrogen recovery stream; performing simulation solution on the substance mathematical model and the energy mathematical model to obtain a simulation operation result as a system initial value of the hydrogen system; according to a preset hydrogen consumption prediction model, obtaining a hydrogen consumption calculation result corresponding to the hydrogen using unit; and determining the value of each optimization variable by taking the minimum energy consumption of the hydrogen system as a target according to a hydrogen consumption measurement result. According to the method, firstly, the accuracy of the hydrogen consumption result value is improved, and then the objective function and the mathematical model are established from the angle of energy consumption minimization of the hydrogen system, so that parallel optimization of the hydrogen consumption and the energy consumption of the hydrogen system is achieved.

Description

technical field [0001] The invention relates to the field of oil refining and processing, in particular to storage, hydrogen resource optimization of hydrogen systems, devices and equipment. Background technique [0002] In recent years, the demand for hydrogen in refineries has been increasing, and hydrogen has become the second largest cost factor in the cost of raw materials for enterprises after crude oil. The optimized utilization technology of hydrogen resources in the hydrogen system is an important means for enterprises to reduce costs and increase efficiency, and has received more and more attention from enterprises. [0003] The composition of the hydrogen system in the refinery is complex, and the hydrogen-containing stream is transported between the "hydrogen supply device-hydrogen consumption device-hydrogen recovery device", which involves the purification, pressurization, waste hydrogen recovery and other processes of the hydrogen stream, and the system consum...
