This paper demonstrates the design and implementation of a binary distillation and collection of Ethanol-Water solution. The PLC based distillation and collection of the liquids is one of the innovative industrial automation projects. The conventional design contains a PLC based automated model of liquid distillation and collection systems, where PLC (SIMATIC S7-300) is used as the controlling brain of the system and distillation and collection are the two main units of the designed system. The distillation control system separates the homogeneous mixture of water and alcohol (ethanol) by comparing the current temperature of the solution of the continuous solution feeding to the column with the boiling points of individual compounds and collection system collects the separated solvents into the bottles placed on the conveyor belt. The monitoring and controlling of the whole systems are evaluated on the basis of temperature and level of the specific units under consideration of atmospheric pressure. Thus the accurate working of process control can lead to smooth operation of the system, preventing unwanted failures, shutdowns and providing notable cost saving and reliability.
