Abstract
Combined with a practical project,the hydrogen production and utilization process scheme of chlorine alkali tail gas,a chemical by-product is ex-pounded.The overall process route is divided into 3 u-nits,purification unit,storage unit and utilization unit.The purification unit includes four stages:raw gas pressurization,pressure swing adsorption purification,catalytic deoxidation and temperature swing adsorption drying.The raw gas is pressurized by a compressor.Pressure swing adsorption purification includes seven steps:adsorption,pressure equalization and pressure reduction,sequential release,reverse release,flushing,pressure equalization and pressurization,and product gas boosting.Catalytic deoxidation uses catalyst for de-oxidation.Temperature swing adsorption drying in-cludes three steps:adsorption,regeneration and cold blowing,mainly to remove moisture.The purified hy-drogen is stored in hydrogen tanks,part of it is used for hydrogen fuel cell power generation,and the other part is compressed by hydrogen compressor for hydrogen pressure filling.关键词
