摘要
结合实际项目,阐述化工副产品氯碱尾气提纯制氢及利用工艺方案,其总体工艺路线分为3个单元,提纯单元、储存单元、利用单元.提纯单元包括原料气增压、变压吸附提纯、催化脱氧、变温吸附干燥4个工段.原料气利用压缩机进行增压;变压吸附提纯包含7个步骤:吸附、均压降压、顺放、逆放、冲洗、均压升压、产品气升压;催化脱氧使用催化剂进行脱氧;变温吸附干燥包括吸附、再生、冷吹3个步骤,主要除去水分.提纯后的氢气储存于氢气储罐,一部分用于氢燃料电池发电;另一部分经氢气压缩机压缩,用于氢气加压充装.
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.
