Title: | Stochastic optimization-based approach for simultaneous process design and HEN synthesis of tightly-coupled RO-ORC-HI systems under seasonal uncertainty | Authors: | Chen, Z Lu, Z Zhang, B Chen, Q He, C Yu, H Ren, J |
Issue Date: | 31-Dec-2021 | Source: | Chemical engineering science, 31 Dec. 2021, v. 246, 116961 | Abstract: | The use of waste heat powered wastewater desalination by coupling an organic Rankine cycle (ORC) with reverse osmosis (RO) has been recognized as a promising solution to desalination. Herein, a tightly-coupled system that allows for optimally customizing the RO-ORC to a background process via heat integration (HI) is developed to minimize the expected desalination cost, while accounting for the seasonal wastewater variability. Moreover, the developed RO-ORC-HI system can improve the membrane permeability by preheating the feed wastewater. To achieve these goals, a stochastic optimization-based solution strategy is proposed by sequentially considering (1) a Pinch-based Duran-Grossman model embedded with uncertainty realization for performing optimal HI during process optimization; (2) a flexible multi-scenario heat exchanger network (HEN) synthesis model that minimizes the total annualized cost of HEN based on a customized stage-wise superstructure. Finally, the behaviors of the proposed system and solution strategy are illustrated through its comparison with a deterministic solution. | Keywords: | Duran-Grossman model Flexible HEN synthesis Rankine cycle Reverse osmosis Seasonal uncertainty Stochastic optimization Waste heat powered desalination |
