The purpose of this project is to develop methodologies for the design and/or retrofit of environmentally benign water cycles in chemical processing units. To address the design and retrofit task, the State Space Approach will be used. This method has been successfully used to combine heat and mass exchanger pinch calculations in a single optimization technique, departing from inefficient sequential methods. The State Space approach can also enlarge the scope of the studies to consider process changes that may allow better pollutant interception. The concept of zero water discharge refers to closed circuits of water, where water disposal is eliminated altogether. Closed circuits are appealing because end-of-pipe regeneration does not have to be conducted to the full extent required for disposal as water can be reused with higher level of contaminants. Additionally, the absence of a discharge eliminates internal administrative costs associated with the enforcement of EPA and local limits, as well as the interface with government agencies.
This project will have a significant impact on water usage and wastewater management for the chemical and petrochemical industry.
