Design and optimization of multi-component organic rankine cycle using liquefied natural gas cryogenic exergy

Simulation and optimization of multi-component organic Rankine cycle integrated with post-combustion capture process

“…The proposed ORC uses a multicomponent mixture of refrigerants as its working fluid. The working fluid includes normal pentane, tetrafluoromethane, and trifluoromethane (Lee et al, 2014a). The multi-component working fluid can be liquefied over a range of more than 50 • C and provide a better temperature match with an LNG evaporation curve compared to pure-substance working fluids.…”

Thermodynamic analysis for working fluids comparison in Rankine-type cycles exploiting the cryogenic exergy in Liquefied Natural Gas (LNG) regasification

“…By using auxiliary thermodynamic cycles operating between seawater as the hot source and LNG as the cold source, a regasification plant may benefit from recovering both the mechanical and thermal exergy available [2]. Rankine Type Cycles (RTC) are the most promising for large scale applications, as discussed in the literature [1][2][3][4][5][6] although other cycles, e.g. the Stirling [7] and Kalina [8] cycles have also been put forward.…”

Design and optimization of cascade organic Rankine cycle for recovering cryogenic energy from liquefied natural gas using binary working fluid

“…Selecting the appropriate working fluids is one of the most relevant issues. Previous works have suggested various working fluids in order to elevate the cycle efficiency, including ternary organic mixtures [9], and zeotropic mixtures [10]. Also, many studies have been made to evaluate the performance of different working fluids by applying different modeling and optimization techniques [11e25].…”
