Abstract: Under the background of “double carbon”, the hydrogen producingusing balance of refineries is facing reconstruction. Developing and popularizing hydrogen saving process technology is becoming more and more important. Hydrogen saving process technology might be improving hydrogen utilization efficiency of traditional hydrogenation process and reduce hydrogen consumption of the unit relying on development of catalyst or process progress. Hydrogen saving process technology also might be developing innovative alternative processes to greatly reduce hydrogen consumption or even no hydrogen consumption. This paper summarizes the technical characteristics of various hydrogen saving processes. Compared with the traditional process, naphtha adsorption separation process obtains highquality ethylene feedstock through non hydrogenation process and reduces hydrogen consumption; S Zorb process can significantly reduce hydrogen consumption; Jet fuel and diesel liquid phase hydrogenation technology cancels the circulating hydrogen process; Diesel low hydrogen consumption high efficiency upgrading technology and adsorption separation process reduces the hydrogen consumption; Sodium desulfurization technology can obtain ideal desulfurization effect under the condition of low hydrogen consumption; Micro interface strengthening mass transfer technology has achieved good results in improving mass transfer efficiency and reducing the hydrogen cycle. After a refinery adopted S Zorb to replace gasoline selective hydrogenation process, the hydrogen production load of hydrogen production unit decreases from 12,800 TPY to 5,730 TPY.
