On the design of crystallization‐based separation processes: Review and extension

Abstract

An analysis is given of various aspects of the design of crystallization-based separation processes. A literature review is included for each of the different themes treated in the study. Special emphasis is placed on the usefulness of the relative composition diagram as a tool for identification of possible flow sheets for separations based on fractional crystallization. A series of rules are derived that may be of practical value in the use

A novel hollow fiber membrane‐assisted antisolvent crystallization for enhanced mass transfer process control

“…Antisolvent crystallization plays an important role in various fields as an effective separation and crystal manufacturing technology (e.g., inorganics, pharmaceuticals, food, and thermosensitive substances). Because it can be operated under ambient temperature and atmospheric pressure, antisolvent crystallization is environment friendly and low energy consumption .…”

Controlled precipitation of nesquehonite (MgCO3·3H2O) by the reaction of MgCl2 with (NH4)2CO3

“…In the last 15 years, the development of new methodologies for design and operation of crystallization-based separation processes has become of interest to the chemical process sector [2][3][4][5]. For the usage of MgCl 2 resource the preparation of hydromagnesite (Mg 5 (CO 3 ) 4 (OH) 2 Á 4H 2 O) [6] or magnesium hydroxide [7] through different methods has been proposed.…”

Thermodynamics of salt lake system: Representation, experiments, and visualization

“…While process synthesis procedures based on SLE phase diagrams are well‐established7–9 and optimization methods have been proposed,10–13 a salt lake system poses special challenges. First, with a large number of electrolytes, a high‐dimensional phase diagram is required for complete representation of the phase behavior.…”
