Topic Name : Importance of Pervaporation for Recovery of Volatile Organic Compounds
Expert Name : Prof. Ashish Modi
Audians : All 6th & 4th Semester students of Chemical Engineering Department

The term pervaporation is derived from the two steps of the process, permeation through the membrane by the permeate, then its evaporation into the vapor phase. This process is used by a number of industries for several different processes, including purification and analysis, due to its simplicity and in-line nature. The membrane acts as a selective barrier between the two phases: the liquid-phase feed and the vapor-phase permeate. It allows the desired component(s) of the liquid feed to transfer through it by vaporization. Separation of components is based on a difference in transport rate of individual components through the membrane.

Topic Name : Optimum Design and Operation of the Batch Reactor
Expert Name : Prof. Suchen B.Thakore
Audians : All 8th and 6th Semester students of Chemical Engg. Department

Batch processes play a very significant role in the chemical process industry. Because of their great flexibility, they are extensively used in the production of fine and specialty chemicals, Pharmaceuticals, Polymers, and bio- products, as well as other products for which efficient and continuous production is not feasible. Thus, batch processes contribute to a significant proportion in the world’s chemical production (especially in value). They are used for liquid phase reaction that requires fairly long reaction time. The batch reactors are used for beverage processes. The increasing technological trends towards the manufacturing of specialty chemicals make the efficient design and operation of batch processes even more important.
