The conventional two-step thermal processing of phosphoric acid wastes enormous amounts of energy, which causes serious environmental pollution in addition to bad economic performance. A two-step waste heat recovery method using a “phosphorus burni

Pentafluoroethane (HFC-125) and trifluoroiodomethane (CF3I) are considered as promising refrigerant alternatives, especially as components in mixtures, to replace CFCs or HCFCs. Effective uses of HFC-125 and CF3I require that the thermophysical prope

The speed of sound of the gaseous 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) was measured for temperatures from 273 to 333 K and pressures from 26 to 315 kPa with a cylindrical, variable-path acoustic interferometer operating at 156.252 kHz. The un

A vapor pressure equation has been developed for 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) based on previous measurements from 202 to 375K, from which the boiling point of HFC-227ea was determined. Based on the previous pressure–volume–tempera

The absorption heat transformer (AHT) is a promising system for recovering waste heat. It can effectively recover about 50% of the waste heat and reuse it in industrial processes. However, there exists a need for identifying suitable working fluid co

A method is proposed to predict the liquid thermal conductivity of HCFC and HFC refrigerant mixtures, using the thermal conductivities, the molecular weights, the mass and mole fractions, the critical temperatures and the dipole moments of the compon
