This thesis studies, develops, analyzes and assesses the performance of three dimethyl-ether production integrated systems, where dimethyl-ether is produced from carbon dioxide and renewable hydrogen. The three systems are fully operated by waste heat and renewable energy. The first system consists of a proton exchange membrane electrolyzer system, carbon capturing system and heat recovery from cement furnace, methanol synthesis system and dimethyl-ether synthesis system. The second system consists of a solar heliostat field, solid oxide steam electrolyzer, carbon capturing and heat recovery system from steel furnace, methanol synthesis system and dimethyl-ether synthesis system. The third system consists of gas turbine cycle, Cu-Cl thermochemical hydrogen production cycle, carbon capturing system and heat recovery from gas turbine exhaust gas, methanol synthesis system, dimethyl-ether synthesis system and multi-effect desalination system. Modeling studies and simulations are performed using both Aspen Plus, and Engineering Equation Solver software packages. These three systems are thermodynamically assessed based on energy and exergy efficiencies. The overall system's energy and exergy efficiencies resulted in 40.46 % and 52.81 for the first system, 28.75% and 32.54% for the second system, and 39.72% and 55.2 % for the third system.","abstract_html":"Dimethyl-ether (DME) is considered to be one of the most promising, renewable alternative fuels.
