Abstract
Semibatch crystallizers are widely used in the chemical industry for the manufacture of many chemicals in a variety of operating modes. Similar to batch crystallizers, they are generally useful in small-scale operations as they are simple, flexible, require less investment, and generally involve less process development. As well as being an important mode of operation, semibatch operation may result from the dynamic conditions that arise either involuntarily imposed, as in start-up or shut-down periods for continuous crystallizers, or voluntarily imposed, to achieve the desired crystallizer behavior. In addition to their flexibility and ease of operation, semibatch operations reduce the severity of the heat effects, prevent the formation of undesired by-products, and/or improve the quality and yield of the desired product in a process sequence. These are some of the advantages that may be exploited from a variety of semibatch operations.
