20160621 University Twente – Mr. Louis van der Ham – “A systems engineering based evaluation of an intensified reactor-separation-recycle process for dimethyl carbonate”

The idea was to employ PSE and PI tools for defining a direct green route to produce the platform chemical Dimethyl Carbonate (DMC) from CO2. Different process routes were investigated. The CO2 + MeOH to DMC route was selected. However the equilibrium should be shifted considerably to make it economical.

A catalytic membrane reactor with selective water removal through the membrane in combination with distillation for DMC purification was analysed technically and economically. This arrangement is technically possible, but economically not feasible mainly due to limitations in improving CO2 conversion that could not be resolved. Equipment cost and energy demand are high and the CO2 balance negative. www.utwente.nl/tnw/spt/
