A Detailed Process and Techno-Economic Analysis of Methanol Synthesis from H2 and CO2 with Intermediate Condensation Steps

In order to increase the typically low equilibrium CO2 conversion methanol using commercially proven technology, addition of two intermediate condensation units between reaction steps is evaluated in this work. Detailed process simulations with heat integration and techno-economic analyses synthesis from green H2 captured are presented here, comparing proposed conventional approach. new process, a single-pass 53.9% was achieved, which significantly higher than (28.5%) its (30.4%). Consequently, total recycle stream flow halved, reduced reactant losses purge compression work streams, lowering operating costs by 4.8% (61.2 M€·a?1). spite additional number exchangers flash drums related units, fixed investment improved decreased 22.7% (94.5 M€). This consequence increased rates lower flows, reducing required size main equipment. Therefore, beneficial for H2/CO2, boosting conversion, consequently reduces both costs.
