Abstract: Industrial processes need to be controlled for the purpose of maintaining quality, consistency, enhancing productivity, ensuring safe operation, maximising profits and complying with regulatory authorities. Distillation is one of the important unit operations in many Industries and hence various controls and control schemes associated with distillation operation are discussed here.
Also the schemes discussed in this paper are for separation of binary mixture.
