A Process Integration Approach to Water Conservation of a Coal to Methanol Plant Water System

Abstract:

A case study of water using network of a coal to methanol plant was under taken with an aim to reduce freshwater consumption, and the accumulated water pinch was employed for minimization of freshwater consumption. The problem was identified as a single contaminant, reuse directly problem. The limiting constraint (i.e. COD) was identified based on the investigation of water quality. A nearest neighbor algorithm (NNA) was used to distribute the fresh water and reuse water among each of operations. The results showed that the flow rates of freshwater and wastewater could be decreased by 24.2% and 86.7%, respectively.
