Abstract

The invention provides a hydrogen recovery system collaborative optimization method and system. The method includes: establishing a mathematical simulation model of the hydrogen recovery system, the hydrogen recovery system including a pressure swing adsorption unit and a membrane separation unit; Solving, obtaining the product hydrogen composition and flow rate output by the hydrogen recovery system; judging whether the product hydrogen composition and flow rate in the solution result meet the preset calculation requirements, and if they meet the preset calculation requirements, then establish the overall optimization of the hydrogen recovery system model, and respectively establish the subsystem optimization models of the pressure swing adsorption unit and the membrane separation unit in the hydrogen recovery system; respectively optimize and solve the subsystem optimization models of the pressure swing adsorption unit and the membrane separation unit, and optimize the The optimization solution result of the model determines the optimization solution result of the overall optimization model. The invention can maximize the benefit of hydrogen recovery.

Description

technical field [0001] The invention relates to the technical field of hydrogen resource optimization research in a refinery, in particular to a hydrogen recovery system collaborative optimization method and system. Background technique [0002] With the intensified trend of heavy and inferior processed crude oil and the strengthening of product quality upgrading requirements, hydrogen is becoming increasingly important in the refinery to ensure the production of qualified products, and the high cost of hydrogen production and investment in hydrogen production equipment make the recovery of hydrogen Particularly important. [0003] For refineries, common hydrogen recovery technologies mainly include pressure swing adsorption technology and membrane separation technology. The pressure swing adsorption method uses solid adsorbents such as silica gel, activated carbon, and molecular sieves installed in vertical pressure vessels to selectively adsorb various impurities in the m...
