Optimization of fixed bed methanation processes

Prior to optimization of methanation processes, heat exchanger optimization is performed; computer simulation of methanation process is then programmed based on kinetic information, cost information and heat and material balance; suitable techniques of optimization of methanation processes are selected and optimum conditions and designs of a various systems are found; various systems of catalytic fixed bed reactors are considered - adiabatic system, heat extraction system, cold quench system and recycle system; size of plant was for production of 250 x 10/sup 9/ Btu/day of pipe line gas. 17 references.
