Title : Considering the concept of total chemical, energy, water, and cost consumption in optimizing process sustainability—not just total direct cost
Abstract:
The parameters related to estimate operational cost including utilities, feed, chemicals, labour and logestics; in which, water, energy, and chemicals have a concept of deeper foot print including the distance from factory, alternatives of design process without high needed chemicals, alternative of usage the recycled energy and water from neighbor factories, and the futurology of underground water resources. In addition, some new index might be suggested in economical evaluation containing index of gap from decarbonization criteria, coefficient of non-neighbor portion of that water and energy of the region facility, and coeeficient of downward chain from products in such a way that keep enough profit to switch the product in a greener and more desirable sustainable outlet. Furthermore, two example of academic and industry case will be interpreted to proclaim the theory more. A academic case of CO2 capture and conversion utilization to carbon and a study of glycol dehydration of sweet gas.
