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...
