The method comprises the following steps of: establishing a multi-lumped desulfurization reaction kinetic model according to a diesel oil hydrodesulfurization process; on the premise of not increasing equipment investment, establishing a hydrogen network optimization model by taking maximum recovery of hydrogen as a guide and taking maximum hydrogen network operation benefit as a target; by taking specific working condition data as input parameters, calculating product property data through the desulfurization reaction kinetic model; when the product property data does not meet a preset condition, updating the working condition data; when the product property data meets the preset condition, outputting a new hydrogen boundary condition and a small molecule hydrocarbon generation amount to the hydrogen network optimization model; and generating a hydrogen optimization scheme according to the hydrogen network optimization model. The method can be suitable for obtaining accurate results under various working conditions, so that a practical and feasible optimization scheme can be obtained, and the method has remarkable economic benefits.

Description

technical field [0001] The invention relates to the field of industrial measurement, in particular to storage, a hydrogen network optimization method, device and equipment based on original equipment. Background technique [0002] In order to meet the requirements of crude oil degradation, product quality upgrading, and clean production, the processing capacity of catalytic hydrogenation units in refineries is increasing, and the operating severity is also increasing, resulting in an increasing demand for hydrogen. Hydrogen has become the second largest cost element in refinery feedstock costs after crude oil. Therefore, how to reduce the cost of hydrogen has become a topic of great concern to refineries; reducing the hydrogen cost of refineries by optimizing the hydrogen network to improve the hydrogen management level of refineries can obtain significant economic benefits.

Problems solved by technology

[0005] After research, the inventor found that the optimization method in the prior art is more suitable for refineries that process a single oil product and a single operating condition; in the application scenario where the refinery in my country processes complex and changeable oil types and the operating conditions often change In the next case, using the material consumption / generation model regressed from the material balance data of a single working condition to calculate the product properties and material consumption under other working conditions will make the accuracy of the results very poor and a good optimization effect cannot be achieved

[0006] Therefore, the hydrogen pipeline network optimization scheme in the prior art cannot be applied to the application scenarios with changing working conditions in my country
