Regarding the increased energy consumption of the processes at the operational units in the National Iranian Oil Company, the present study analyzed energy consumption at one of the gas refineries. In this refinery, which is the main supplier of Fajr Jam refinery for the national gas network, as well as an injection into the oil fields of the Iranian South oil company, the pressure of gas after...

Joule-Thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. Although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. In the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic Joule-Thomson cooling system...

In the present work, we have examined the ability of some different equations of state in predicting the Joule-Thomson coefficient, ?J-T, of different fluids. For dense fluids, for which density is greater than the Boyle density, ?B, two appropriate equations of state, namely the linear isotherm regularity, LIR, and the dense system equation of state, DSEOS, have been examined. The results show...

The process of the Joule–Thomson adiabatic expansion within rational NED (RNED)-AdS spacetime is investigated. isenthalpic $$P{-}T$$ diagrams and inversion temperature are depicted. depends on magnetic charge RNED coupling constant black holes. When coefficient vanishes, a cooling-heating phase transition occurs. We consider cosmological as thermodynamic pressure, hole mass treated chemical ent...

Abstract In this paper, the Joule-Thomson expansion of Born-Infeld AdS black holes is studied in extended phase space, where cosmological constant identified with pressure. The coefficient, inversion curves and isenthalpic are discussed detail using a 4-dimensional hole. critical point hole depicted varying parameter charge Q . T-P plane, temperature obtained different We fi...
