August semester (conducted in Room F01 on Tuesdays and Thursdays, between 12 -12:50 pm):
Undergraduate-level: UEES 313 - Experimental Methods In Environmental Engineering (theory and lab)
The theory section of this course looks into purification and separation technologies that form the backbone of society and industry. Whether it is separating out impurities from water before drinking, removing carbon dioxide from air to maintain a healthy atmosphere, or even keeping out the Covid-19 virus using a mask, purification and separation technologies are critical in our sustainable and healthy living. The course covers fundamental mechanisms involved in several separation technologies, and subsequently, the engineering design of the system is taught so that the student can design practical systems in applications of their choice. The laboratory section of the course provides hands-on experience for all technologies taught in class. Lab activities include dye adsorption and desorption from water in a prototype of a practical adsorption column, carbon dioxide absorption in an absorption column, salt crystallization for zero liquid discharge. A student project is to be performed such that both theoretical techniques taught in class can be implemented, and demonstration of the project in lab will be required.
Post-graduate level: ST219 - Separation Technologies for Sustainable Industrial Processes
This course looks into separation technologies with primarily an industrial focus. Consider any product that you use from the time you wake up till the end of the day - plastics, paper, pharmaceuticals, soaps and detergents, textiles, and many more. In this course, we focus on an important set of steps in the manufacture of such items that are critical in our daily lives, namely the ‘chemical separation’ steps. Such chemical separations typically account for 40-70% of the total cost of the complete manufacture process of the item. Cumulatively, separations in various industries add up to 15% of the world’s energy requirements. However, chemical separations and the concerned separation technologies are responsible for several important processes, such as extracting the final product from the synthesis medium; treating effluent streams before environmental discharge; recovering materials that can be reused for subsequent manufacture cycles; or isolating valuable intermediate products that can be used in a different industry, or sold. This course covers thermodynamic analysis of separation systems, mechanisms applicable to several important separations, system design for practical applications. A student project is a part of the course instruction, and allows familiarization of the student with the concepts taught in class.
Detailed syllabus: Major industrial separation methods, namely distillation, membrane separations, adsorption, absorption, and liquid-liquid extraction; basic design and analytical methods for the aforementioned technologies; thermodynamic analysis and second law efficiency; economic analysis; case studies on important practical separation problems; ecological impact of proposed technology in case study.
