As a separation method The need to purify solutions is common in chemistry and chemical engineering since it may be necessary to obtain a product that is homogeneously mixed with another or other dissolved substances This is why equipment and methods have been developed to carry out crystallization as an industrial separation process

In the separation plant this pressure is reduced This is done in so called high pressure separators and mid or low pressure separators This process is a continuous process where at the front of the separator the liquid/gas is constant added The gas is released at the top and the oil water mixture is separating by using gravity and chemicals
