“…Crystallization of ionic salts [18][19][20], metal ions [21], low molecular organic acids [22][23], proteins and pharmaceutical compounds [24][25][26][27][28] are examples of the applicability of this technology. In addition, the main advantages of membrane crystallization have been already demonstrated: 1) it is possible to control the maximum level of supersaturation due to a defined mass transfer through the membrane [29]; 2) the membrane induces heterogeneous nucleation; 3) size, shape and purity of crystals can be controlled; 4) there is a significant reduction of energy consumption compared to conventional crystallization by means of cooling or evaporation [30]; and 5) comparable or slightly higher nucleation rates with respect to batch crystallizers or tubular precipitators have been obtained [24].…”

The interest in combining membrane operations and solution crystallization is motivated by the aim to develop more efficient crystallization processes. Membranes, with their intrinsic characteristics of efficiency and operational simplicity, high selectivity, and permeability for the transport of specific components, compatibility between different membrane operations in integrated systems, low energetic requirement, good stability under operating conditions and environmental compatibility, easy control and scale-up, and large operational flexibility, represent a technology that well satisfies the concept of the rationalization of chemical productions, leading to significant innovation in both processes and products. Accordingly, membrane technology provides significant improvements in crystallization. This approach has been put in practice in a number of membrane-assisted crystallization (MAC) configurations. The main features of MAC are:

“…The final process used for the production of solid solute is by a reaction or precipitation crystallisation assisted by mass transfer through a membrane as seen in Fig. 2.3 [78,93]. An example of how membranes have been used for precipitation was reported by Kieffer et al [78,93] where they used a hollow fibre membrane to pass through a solution of barium chloride to react with potassium sulphate to attain barium sulphate.…”

“…Schematic representation of different membrane crystallisation solidification processes[67]. The dilution and reaction supersaturation modes correspond to antisolvent crystallisation and precipitation processes respectively.There are generally five different membrane crystallisation approaches for the formation of solid material[67,68,[71][72][73][74][75][76][77][78][79]. Currently, membrane crystallisation has either been used as a means for creating supersaturation and nucleation before the liquid of interested is transferred into a crystalliser (hybrid membrane crystallisation)[66,67,80], or where nucleation and crystal growth occurs near the surface of a membrane unit (integrated membrane crystallisation)[67,[81][82][83].…”

Novel percrystallisation process by inorganic carbon membranes

This thesis demonstrates, for the first time, the use of sucrose derived inorganic membranes for crystallisation. In addition, this thesis also shows, for the first time, a process where solvents and solutes are separated in a single step, contrary to polymeric membrane crystallisation which requires two extra steps downstream to filter and dry crystals. There are two further major aspects of this first demonstration as a contribution to the body knowledge in the area of crystallisation. The third novelty is the demonstration of the percrystalisation transport mechanism, occurring as the solution permeates through the membrane where a wet thin film is formed on the permeate face of the membrane. The wet thin film forms a solid-liquid-vapour interface. At this interface, effective evaporation of the solvent occurs under a vacuum, resulting in the crystallisation of the solute on the membrane surface. Hence, a unique single step separation process occurs as the solvent evaporates and concomitantly the crystallised solute is continuously ejected from the surface of the membranes. This novel process is called percrystallisation reflecting the single step permeation and crystallisation. Additionally, this process is able to produce essentially pure water at rates comparable to reverse osmosis. This is possible, even at a concentration that far exceeds the capabilities of reverse osmosis. Further, high production crystallised solute rates are achieved as one metre square of membrane can deliver crystallised NaCl fluxes of up to 48,000 kg m-2 per year. The fourth additional demonstration is related to morphology of the membrane and process operations in affecting crystal formation. For instance, by varying carbonisation temperature and feed temperature or vacuum pressure, it is possible to tune the crystallite size and particle size state of the treated solute. Indeed this thesis demonstrates how sodium chloride particles are produced with a much smaller and narrower particle size distribution compared to conventional methods. Likewise, changes in the carbon content of the membrane, feed temperature, and feed concentration are able to produce nickel sulphate with different hydration states. This thesis further shows examples how versatile membrane percrystallisation can be for processing several types of solutes such as paracetamol (a pharmaceutical analgesic), Vitamin C (food and pharmaceutical compound) and several nitrate and sulphate salts for hydrometallurgy applications. This thesis opens a window of research opportunities to effectively crystallise compounds of interest for a wide spectrum of industries.
