摘　　要：为了指导炼油厂优化制氢原料的选择,利用Aspen Plus流程模拟软件建立了制氢工艺模型,对采用不同制氢原料的蒸汽重整制氢装置的物耗、综合能耗、碳排放强度和H 2成本进行了研究。结果表明,采用不同制氢原料时,制氢装置的原料单耗、综合能耗和碳排放强度(以生产单位质量H_(2)计)分别为2.75~3.36 t/t,1031.24~1494.25 kgOE/t(1 kgOE≈41.8 MJ),7.75~11.28 t/t,与制氢原料的碳含量成正相关。采用不同制氢原料时,H_(2)生产成本介于11884~20597元/t之间,由高到低的顺序为石脑油>>加氢干气≈变压吸附(PSA)解吸气≈芳烃干气>天然气≈焦化干气。随着碳交易价格不断上涨,炼油厂不宜选用石脑油作为制氢原料,碳含量较低的炼厂气(芳烃干气、加氢干气和PSA解吸气)较天然气和焦化干气更具优势。In order to guide the refinery to optimize the selection of raw materials for hydrogen production,a hydrogen production process model was established by using Aspen Plus process simulation software,and the material consumption,comprehensive energy consumption,carbon emission intensity and hydrogen cost of steam reformer using different raw materials were analyzed.The results showed that the unit consumption of raw materials,comprehensive energy consumption and carbon emission intensity of hydrogen plant were 2.75-3.36 t/t,1031.24-1494.25 kgOE/t and 7.75-11.28 t/t respectively,which were positively correlated with the carbon content of raw materials.Besides,the cost of H_(2)for different hydrogen production raw materials was 11884-20597 Yuan t,the order from high to low was naphtha>>hydrogenator dry gas≈desorption gas of pressure swing adsorption(PSA)≈aromatics unit dry gas>natural gas≈coker dry gas.As carbon prices continued to increase,refineries should not use naphtha as raw material for hydrogen production,and refinery gas(aromatics unit dry gas,hydrogenator dry gas and PSA desorption gas)with lower carbon content had advantages over natural gas and coker dry gas.
