Comparison of reformulations of the Duran-Grossmann model for Work and Heat Exchange Network (WHEN) synthesis
Yu, Haoshui; Vikse, Matias; Gundersen, Truls (Journal article; Peer reviewed, 2018)Work and Heat Exchange Networks (WHENs) have received increasing attention from both researchers and engineers during the last 5-10 years. The Duran-Grossmann model (Duran and Grossmann, 1986) can deal with heat integration ... -
Identifying optimal thermodynamic paths in work and heat exchange network synthesis
Yu, Haoshui; Fu, Chao; Vikse, Matias; He, Chang; Gundersen, Truls (Journal article; Peer reviewed, 2018)The process synthesis problem referred to as work and heat exchange networks (WHENs) is an extension of the classical heat exchanger networks problem considering only temperature and heat. In WHENs, additional properties ... -
Model reformulations for Work and Heat Exchange Network (WHEN) synthesis problems
Yu, Haoshui; Vikse, Matias; Anantharaman, Rahul; Gundersen, Truls (Journal article; Peer reviewed, 2019)The Duran-Grossmann model can deal with heat integration problems with variable process streams. Work and Heat Exchange Networks (WHENs) represent an extension of Heat Exchange Networks. In WHEN problems, the identities ... -
Modeling and Optimization of Simultaneous Waste Heat Utilization and Wastewater Treatment Processes
Yu, Haoshui; Chen, Zhichao; He, Chang; Gundersen, Truls (Chapter, 2019)Huge amounts of low-temperature waste heat, which can be utilized to improve the energy efficiency in various ways, are available in the process industries. Organic Rankine Cycle (ORC) is one of the promising technologies ... -
Organic Rankine Cycle with Pure and Mixed Working Fluids for LNG Cold Energy Recovery
Yu, Haoshui; Kim, Donghoi; Hu, Xiangping; Gundersen, Truls (Journal article; Peer reviewed, 2019)Liquefied Natural Gas (LNG) contains a large amount of cold exergy, which is normally wasted during the regasification process. Organic Rankine Cycles (ORCs), which have been widely employed for low-temperature waste heat ... -
Process integration of organic Rankine cycle (ORC) and heat pump for low temperature waste heat recovery
Yu, Haoshui; Gundersen, Truls; Feng, Xiao (Peer reviewed; Journal article, 2018)Organic Rankine cycles (ORCs) have been a mature technology for low temperature waste heat utilization. However, the relatively low thermal efficiency and incomplete waste heat recovery limit the power output of ORC systems. ... -
Process optimization and working fluid mixture design for organic Rankine cycles (ORCs) recovering compression heat in oxy-combustion power plants
Yu, Haoshui; Eason, John; Biegler, Lorenz T; Feng, Xiao; Gundersen, Truls (Peer reviewed; Journal article, 2018)In this study, an Organic Rankine Cycle (ORC) is proposed to be integrated with the flue gas pre-compression process to reduce the energy cost resulting from Carbon Capture and Storage (CCS). An equation-based flowsheet ... -
