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 …

13.2: Specific Heat

In SI units, heat capacity is expressed in units of joules per kelvin (J/K). An object's heat capacity (symbol C) is defined as the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object. C = Q ΔT. (13.2.1) (13.2.1) C = Q Δ T. Heat capacity is an extensive property, so it scales ...

Ammonium Sulfate | Formula, Properties & Application

This process is often associated with other industries such as the production of caprolactam, where ammonium sulfate is a by-product. The reaction can be represented as: 2NH 3 + H 2 SO 4-> (NH 4) 2 SO 4; Ammonium sulfate is also produced from gypsum, which is calcium sulfate dihydrate (CaSO 4 • 2H 2 O), via the Haber process. This involves ...
