Analysis of energy saving for ammonium sulfate solution processing with

The single-stage MVR system is presented in Fig. 1.As shown in Fig. 1 (a), the feed with an initial concentration through the PHX1 and PHX2 absorbs the sensible heat from the condensate water and emission solution, and then evaporates through absorbing the latent heat of the secondary steam in HX1. Finally, the feed flows out of the …

Chapter 9.5: Enthalpies of Solution

Substances with large positive or negative enthalpies of solution have commercial applications as instant cold or hot packs. Single-use versions of these products are based on the dissolution of either calcium chloride (CaCl 2, ΔH soln = −81.3 kJ/mol) or ammonium nitrate (NH 4 NO 3, ΔH soln = +25.7 kJ/mol). Both types consist of a plastic …

Large electrocaloric effects in single-crystal ammonium sulfate

Here, we investigate EC effects in an inorganic salt, namely ammonium sulfate (NH 4) 2 SO 4, with an order–disorder transition whose onset occurs at 223 K on cooling. For a single crystal thinned to 50 μm, we use a Maxwell relation to find a large isothermal entropy change of 30 J K −1 kg −1 in response to a field change of 400 kV cm …
