RHT has also developed LCN naphtha selective hydrogenation and mercaptan removal, using a proprietary technique, so as to maximize LCN recovery. This lends itself to gasoline HDS of HCN that has low content of olefins and severe HDS requirements to meet the specification, provide low olefin saturation and lower octane loss than the competing technologies. This optimum configuration provides longer catalyst life with conventional catalyst and lower Opex and Capex
RHT does not use any packaged or proprietary catalyst which is cumbersome to load, and could have maldistribution, fouling is avoided by the optimum configuration and operating conditions. Artificially temperature is not raised in catalyst zone by manipulating the liquid flow in recycle type of reactor which consumes much higher energy and complex heat integration. Catalyst life is still maintained in the normal life cycle experienced in these technologies.
