This study evaluates three refinery schemes that have been developed for the processing of H-Coal liquids. The refinery processing employed for the naphtha and lighter components of the H-Coal liquid is essentially the same for all three schemes. It is in the processing of the H-Coal distillate product that refinery variations occur, and these differences are outlined: hydrotreating of the middle coal distillate to produce a No. 2 fuel oil equivalent product; hydrocracking of the total coal distillate to produce more gasoline and higher quality distillate fuel; and hydrotreating of the light coal distillate to a No. 2 fuel oil equivalent, and hydrogenating the heavy coal distillate to upgrade feedstock to a fluid catalytic cracking (FCC) unit. To provide a perspective of the value of coal liquid relative to petroleum, a parallel set of petroleum refinery schemes, processing a 65/35 Light/Heavy Arabian crude oil blend, was developed: reduced crude desulfurization with FCC processing of the desulfurized VGO; reduced crude desulfurization with hydrocracking of the desulfurized VGO; solvent demetallization of the vacuum pitch with desulfurization and FCC processing of VGO and demetallized oil; and solvent demetallization of the vacuum pitch with hydrocracking of the VGO and demetallized oil. Various gasoline to distillate ratios were set as parameters in developing the best possible processing schemes. Linear programming techniques were used to select the optimal schemes at various product ratios. Applying the same product prices to all cases and subtracting operating costs and the capital change, a comparative feedstock value is calculated. This method places the various refinery schemes on a common basis and gives an appraisal of the relative value of the H-Coal liquid charge stock, based on new refinery facilities.
