PORIFERA, INC. — Department of Energy SBIR Phase II: 17d

Description

Energy production requires significant quantities of fresh water for cooling, emitting greenhouse gases, and generating wastewater. This proposal will development a system that will synergistically capture carbon and treat wastewater at power plants. The system will have higher water recovery and treat more problematic water using less energy compared to state of the art technologies. A feasibility study of the system showed that carbon dioxide could be removed from synthetic flue gas, used to dewater seawater, and removed using lowgrade waste heat. Then a benchscale system was constructed and the process was improved. Further study and optimization of the system with significant technological improvements. The system will capture carbon dioxide to treat wastewater at power plants that currently require extremely expensive and energy intensive methods. The system will reduce the volume of waste water, reduce the energy costs to treat wastewater, expand the capabilities of water treatment, and reduce the cost of carbon capture from flue gas. Key Words – carbon capture, forward osmosis, membrane, draw. This proposal will enable the development of a system that will synergistically capture carbon and treat wastewater at power plants. The system will have higher water recovery and treat more problematic water using less energy compared to state of the art technologies.
