Abstract | Chemicals based products and the processes that manufacture them play important roles in sustaining our society. Chemical, biochemical, petrochemical and related processes are characterized by either conversion of specific raw materials to desired chemicals or extraction of desired chemicals from specific raw materials. Well–known examples in the first category are the conversion of methanol and acetic acid to form methyl acetate and water, and, carbon dioxide hydrogenation to methanol via the reverse water gas shift reaction. In the second category, the use of de–methanizer, de–ethanizer, de–propanizer, and so on, separation steps in gas processing plants are well–known. In the conversion–based processes, as the conversions of raw materials are usually not 100% complete, energy intensive downstream separation techniques need to be employed to separate the desired products and recycle the unreacted raw materials. Note that the conversion process itself may also be energy intensive. In the extraction–based processes where product chemicals do not usually represent 100% of the raw material, energy intensive separation techniques are commonly employed to achieve the desired separations. This means that for both categories of processes, energy in different forms need to be supplied and the processes during operation have the potential to produce waste that may lead to negative environmental impacts and cause supply chain issues. Furthermore, planet earth is facing challenges with respect to energy, water, food, and environment, and significant improvements in process efficiencies of new and/or existing processes are needed. |
