Optimal design of pressure retarded osmosis process for power generation
Name: Kingchat Potisa-ad
LCSH:
Osmoregulation.
Abstract:
The pressure retarded osmosis (PRO) process is an interesting membrane technology for alternative power generation. This technology utilizes an osmotic pressure, obtained by a varied chemical potential from a mixing of two solutions with a different salt concentration, as a driving force of water penetration through a semi-permeable membrane. The permeate water is used to drive a turbine and produce power. The objective of this work is to investigate parameters that affect the performance of the PRO process and design the optimal system. The model simulation was performed by using the MATLAB program.
The results indicated that the limited and unlimited supplies of fresh water had some impact on the performance of the PRO, especially for a long-length membrane module. The flow direction, i.e., concurrent and counter-current flow, had little effect on the performance. The flow configurations showed that feeding fresh draw solution to each stage could maximize the average power density output. It was revealed that the number of stages of more than three was not attractive comparatively. In conclusion, the optimal PRO system has three stages, with fresh draw solution fed at each stage. Compared to a conventional single-stage system with the same membrane area, the optimal design can increase the average power density by 39.04%, resulting in an LCOE of $0.610/kWh.
