The Methanation Unit is designed to convert the carbon oxides in the treated make-up hydrogen to methane. This results in a product gas containing 26.26 MMSCFD hydrogen with an overall hydrogen purity of approximately 94.5 percent (dry basis) and a maximum carbon oxides concentration of 20 ppmv. The design is based on a single operating train as the equipment will have a very high on-stream factor. The treated make-up hydrogen feed from the Selexol Unit is heated by exchange with the Methanator effluent and then desulfurized in a two-stage desulfurization step. The desulfurized hydrogen stream is then methanated in the methanator. The effluent from the methanator is then cooled to 100/sup 0/F and sent to the Hydrocracker Unit for further processing. The treated make-up hydrogen from the Selexol Unit enters the Methanation Unit battery limit at a pressure of 670 psia and a temperature of 60/sup 0/F. The composition of the make-up hydrogen feed to the Methanation Unit is given in Table 1. As the sulfur content of the feed gas is very low, a significant temperature rise in the desulfurizers is not expected. The composition of the Desulfurizer No. 2 effluent (methanator feed) is given in Table 2. Desulfurized make-up hydrogen then enters the Methanator (R-15653). The exothermic methanation reaction then occurs over the catalyst bed raising the gas temperature to 912/sup 0/F (SOR) and 932/sup 0/F (EOR). The composition of the methanator effluent is given in Table 3.
