This work reports a study of the absorption fluorinated refrigerant gases in ionic liquids (ILs) from combined experimental and computational approach to gain insights into solvation these greenhouse gases. The results allow selection solvents for gas recovery, based on molecular characteristics, improve recyclability high-value-added compounds. solubility R-134a, R-1234yf, R-1234ze(E) was meas...

The objective of this work is to assess the sensibility of a computer simulation program, employed to analyse the transient behaviour of· domestic refrigerators, to the adopted capillary tube and condenser mathematical modelling approach. Although all the comparisons, presented in this work, are related to a specific computer program, it is believed that, at least in a qualitative way, they are...

Data is presented for the vapor liquid equilibrium viscosity reduction of lubricants with two refrigerant blends at two temperatures. The lubricants tested were a 32 ISO VG mixed acid polyolester and a 32 ISO VG branched acid polyolester. The refrigerant blends used were HFC-125/143a/134a (44/52/4% w/w), and HFC-125/143a (50/50% w/w). INTRODUCTION This experiment detennined the vapor liquid equ...

The popular pressurized metered dose inhaler (pMDI), especially for asthma treatment, has undergone various changes in terms of propellant use and valve design. Most significant are the choice of hydrofluoroalkane-134a (HFA-134a) as a new propellant (rather than chlorofluorocarbon, CFC), a smaller exit nozzle diameter and attachment of a spacer in order to reduce ultimately droplet size and spr...

The Kigali Amendment to the Montreal Protocol limits global use of fluorinated greenhouse gases (F-gases) and encourages development a new generation refrigerants with lower warming potential. Therefore, there is need develop efficient sustainable technologies selectively capture recycle F-gases as environmentally refrigerants. Here, ionic liquids (ILs) high F-gas uptake capacity selectivity we...
