About the Lab
Chemical Engineering is concerned with modifying raw materials in individual or combined steps of physical, chemical, and biological ways to convert them into desired products. Some of the unit operations directly involved changing the compositions of the mixture to make them separate into individual components. Mostly these all are physical separations and are involved in the preparation of Raw material for the process, and the purification of products at the downstream operations to ensure the quality of the products. Based on the miscible or immiscible nature of phases solid-solid, solid-liquid, solid-gas, liquid-solid, liquid-liquid, liquid-gas, gas-solid, gas-liquid, and gas-gas can select the operations to separate the components of desire. Such operations are Adsorption, Absorption, distillation, decantation, diffusion, extraction, filtration, humidification, leaching, and so on.
The mass transfer Lab at SRMIST has both glass wares type of model set-up as well as for pilot scales like prototype equipment for learning and research purposes. Students Will Learn the fundamentals and can-do research in large-scale operations. and
The academic and research labs were equipped with all the novel equipment facilities. For membrane-based separations, the lab has a facility for hollow fiber membrane fabrication set-up, flat sheet membrane production, membrane distillation unit, and membrane testing kit.
