In order to maximize the economic benefits of the ARGG unit a string of measures, including the modification of catalyst formulation, retention of high catalyst activity, application of mixed termina-tion agents to control the reaction temperature and once-through operation, and optimization of catalyst regeneration technique, were adopted to adapt the ARGG unit to processing of the heavy feedstock with its carbon residue equating to 7 % on an average. The heavy oil processing technology has brought about apparent economic benefits.展开更多

After successful laboratory study this technology had been applied in commercial scale successfully. Compared to traditional caustic wash of distillate oils, this technology has a lot of merits, such as the broad range of distillates to be processed, low caustic consumption, recycle of deacidifying agent, absence of waste caustic discharge, and low equipment revamp expenses, which can have promising perspectives for exploitation and application of this technology.展开更多
