Abstract ：The development of RH vacuum refinery technology in the recent 20 years was summarized. It points out that multifunctional RH is the main tendency. Deep decarburization, degas, desulphurization, dephosphorization, deoxidation, inclusion removal and heat compensation integration are the key technologies to realize the multifunction of RH. Based on it, the technical development of the high efficiency and long life and end point intelligent control were expatiated.
