摘要

This study progresses absorption, mixed refrigerant and mixed fluid cascade refrigeration systems in the integrated cryogenic natural gas plant. It also presents a comprehensive systematic method for designing of refrigeration cycles based on synthesis of mathematic and thermodynamic viewpoints. The possibility of using absorption refrigeration system in lieu of precooling stage of mixed fluid cascade refrigeration cycle with the aim of reducing in energy consumption is investigated. In this way, the high amount of energy consumption in these units because of eliminating of some parts of mixed fluid cascade system has been reduced, and the possibility of using wasted energy of plant has been provided. Then, energy, exergy and economic analyses are carried out using simulated data. Economic analysis is carried out using annualized cost of system for the two structures. Using absorption refrigeration systems as an alternative to compression refrigeration system in the integrated structure causes reduction in the amount of specific power, capital cost, and prime cost of product by 38.94%, 31.9%, and 1531%, respectively. Sensitivity analysis of economic parameters with respect to utilities price as well as products price on the market has been done. (C) 2018 Published by Elsevier Ltd.
