Process modelling and feasibility study of sorption-enhanced methanol synthesis

A sorption-enhanced process for hydrogenation of CO2 to methanol was designed and investigated by mathematical modelling techno-economic analysis. The methodology combined dynamic the cyclic reactor operation with pseudo-steady state overall process. With continuous adsorption water in process, highly pure (>99%) produced without downstream distillation. cycle optimized maximize production rate. were modelled two configurations: adiabatic isothermal. Under default cost assumptions raw materials (CO2 50 €/t, hydrogen 3000 €/t) configuration found more competitive terms cost, at 1085 €/t compared 1255 isothermal case. estimate case comparable a reference representing conventional (1089 €/t). In addition developed modeling method has potential design other processes.
