Abstract

The invention discloses a storage device, and pressure swing adsorption device optimization method, device and equipment. The method comprises the steps: establishing a mathematic simulation model ofa pressure swing adsorption device through employing an adsorption balance equation, a mass transfer rate equation and a total mass transfer balance equation, and setting parameter initial values needed by all directions; performing mathematical solution on the mathematical simulation model to obtain the hydrogen composition and flow of the product, and determining the specific penetration time according to the time required for the carbon monoxide and / or sulfide in the feed gas to penetrate through the special molecular sieve adsorption layer; determining whether the product hydrogen composition in the solving result meets a preset calculation requirement or not; and establishing a nonlinear programming model and solving the nonlinear programming model to obtain the optimal adsorption time of the pressure swing adsorption device. According to the method, the product hydrogen meeting the hydrogen demand of the special industry can be obtained on the premise of not increasing first-stage PSA or other hydrogen purification means, so that the economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to an optimization method, device and equipment for a storage device and a pressure swing adsorption device. Background technique [0002] Pressure swing adsorption is the most important means for refineries to obtain high-purity hydrogen. It mainly uses the principle of "adsorption at high pressure and desorption at low pressure" for impurity components in hydrogen-containing streams to enrich hydrogen. [0003] Pressure swing adsorption devices generally include multiple composite beds of different types of adsorbents. Usually, various types of molecular sieve adsorbents such as activated alumina, silica gel, and activated carbon are filled sequentially from bottom to top. In actual production, the adsorption pressure and regeneration desorption pressure of the pressure swing adsorption device are matched with the upstream and downstream systems, and are basically constant.
