Solvents with an improved price/performance ratio allow for processes with less operating and/or capital expenditure. Therefore, from an industrial perspective, it is worth reviewing the R&D progress in designing new competitive solvents on a regular basis. This paper aims at discussing the potential of new solvent systems applicable as absorbents or entrainers for boosting the performance of a...

The effect of plasma nitriding and oxidation on the corrosion resistance AISI 304 type stainless steel in LiBr/H2O CaCl2-LiBr-LiNO3-H2O mixtures at 80 °C has been evaluated by using potentiodynamic polarization curves electrochemical impedance spectroscopy techniques (EIS). Steel was treated 500 during 8 h under different atmospheres, nominally 20% N2 + 80% H2, 100% O2. X-ray diffraction analys...

Abstract The SiO2-LiBr hybrid porous materials were prepared by the sol-gel method. This process was obtained by the hydrolysis and condensation Tetraethyl orthosilicate (TEOS) with replacement of ethanol from alcogel by the drying at ambient temperature to obtain xerogel structure. The alcogel samples were synthesized from TEOS, EtOH, H2O, HCl, NH4OH and LiBr. The total molar ratio of the comp...

In order to investigate the NH3+H2O+LiBr (lithium bromide) absorption refrigeration cycle process and simulate it accurately, a vapor-liquid equilibrium calculation model was proposed obtain thermodynamic characteristic data of ternary mixtures. The parameters liquid phase is based on Wilson?s equation non-random two equation. vapor phase, assumed consist NH3 H2O only, described by Redlich-Kwon...

The aim of this study is to analyze the feasibility single-effect H2O/LiBr absorption heat pump cycle produce combined heating and cooling. To achieve this, first, main changes that requires are described in comparison with conventional chiller. Then, cycle’s operational limits terms temperature lift LiBr crystallization evaluated. In sense, driving temperatures required for these applications ...
