Extracted text: Considerable interest exists in the conversion of coal into more convenient liquid products for subsequent combustion. Two of the main gases that can be generated under suitable condi- tions from insitu coal combustion in the presence of steam (as occurs naturally in the presence of groundwater) are H2 and CO. After cleanup, these two gases can be combined to yield methanol according to the following equation Со + 2H, CH, OH > Figure E2.29 illustrates the process. Overall System Boundary 67.3 H2 E Feed F{32.5 CÓ Reactor Seporator CH3OH 100% 0.2 CH4 Recycle R Purge P x H2 у СО 2 CH4 You will note in Fig. E2.29 that some CH, enters the process, but the CH4 does not participate in the reaction. A purge stream is used to maintain the CH4 concentration in the exit to the separator at no more than 3.2 mol%. The once-through conversion of the CÓ in the reactor is 18%. Compute the moles of recycle, CH3 OH, and purge per mole of feed, and also compute the purge gas composition.
