Crystallizers are the equipment used for achieving the process of crystallization. In the various industries, the crystallizers are used for the separation process of liquid to solid. The crystallizers are manufactured in such a way that they are able to produce high purity products that too without much energy input. That means crystallizers are highly energy efficient. There are various types of crystallizers available in the market for industrial use. Let’s have a look at some of the popular industrial crystallizers.
Evaporative crystallizers are used for the process of evaporative crystallization. In the process of evaporative crystallization, the solvent gets evaporated which leads to an increase in the concentration of the solution. Due to the increase in concentration, the supersaturation of the solution happens and the process of nucleation starts. As further the nucleation happens, the nuclei grow and change to the crystals. There are basically two types of evaporative crystallizers that are used in industrial crystallization. Draft tube crystallizers and Submerge circulating crystallizers.
The process of Oslo crystallizers is also known as the fluidized bed. In the process of Oslo crystallization, at the bottom of the Oslo crystallizer, the crystals are fluidized or you can say converts in a fluid form from the solid form. The process of fluidization happens with the help of an external axial pump. The pump consists of the mother liquor in the upper part. The technology of Oslo crystallization demands often cleaning, which is already built in the operating principle of the Oslo crystallizers. The process of the Oslo crystallizers includes the central tube clogging with the help of the precipitation process and supersaturation without crystals.
The process of vacuum crystallizers is used sometimes as continuous and sometimes as a batch. The process is of course known as vacuum crystallization. In industrial usage, the batch vacuum crystallizers are more popular than continuous vacuum crystallizers. The batch vacuum crystallizers are used in the process of distillation of the materials. The distilled materials grow on the equipment of continuous crystallization walls. The vacuum crystallizers are used to maintaining the vacuum inside the body of the crystallizer with the help of a condenser booster.
The cooling crystallization happens with the help of the transferring of indirect heat and under the vacuum. The process of cooling crystallization is based on the dependency of the solubility temperature. In the process of cooling crystallization, some of the solutions evaporate and then cooled down. The cooling down of the solution occurs through the reduced pressure in equilibrium. As a result, a little bit of the solvent shines off the concealed heat following the temperature lowering of the solution. The crystallization in the cooling crystallizer happens because of the temperature change of the solution.
