Most industries operational today aim to automate their processes to the greatest extent. Automatic process control, if programmed and maintained carefully, eliminates the human errors that have led to tragic plant-wide accidents in the past. This introductory course covers basics of process control. The course begins with the introductory concepts, followed by the mathematical modelling. This knowledge base will be beneficial to understand the dynamic behaviour of chemical processes. A major focus will be on the design of feedback controllers, including their tuning and stability analysis. Later, discussions on several advanced control systems will introduce the class to actual systems employed in industries. The course ends with exposing the class with designing practical plant-wide control systems.

1. COURSE SUMMARY This course focuses on providing the students with an overview of the Natural Gas (NG) sector. NG finds immense usage in domestic, transportation, fertilizers & other industrial sectors. Accordingly, this course incorporates two modules. The first module will be on City Gas Distribution (CGD), entailing the construction, operation, and maintenance of natural gas distribution systems for the supply of piped natural gas to industrial, domestic, commercial and transportation sectors. The likely voluminous growth of CGD infrastructure requires competent professionals and skilled workforce to execute the projects successfully. Thus, there is a need to identify the gaps in knowledge and develop the skill set required for professionals to groom them for such domains. This in turn, will pave the way for establishing strong energy network within the country. The second module will entail the need and usage of an important product known as Liquefied Natural Gas (LNG). LNG is a highly specialized area in energy, process, and infrastructure industries. Current statistics show that half of the total NG consumed in the country is imported as LNG through ships, and is then re-gasified to feed the NG supply lines. Interestingly, the LNG industry is transitioning from its nascent stage to a grown and matured market in India, and will eventually help in making India as an energy secure nation. 2. COURSE AIMS This preliminary exposure should enable the students to appreciate the principles of occurrence, discovery and production of fluid hydrocarbons. The course aims at orienting the students to: (a) become a better suited candidate for employment in industries, especially the hydrocarbon sector and CGD (project execution, transportation and marketing, operation and maintenance, and allied areas of supervising roles); (b) to have an enriching interaction with industry experts in the form of courseware, experience sharing and case study; and (c) develop successful academic careers in hydrocarbon sector in engineering domains and find avenues of research in natural gas and allied sectors. 3. LEARNING OUTCOMES After successful completion of this course, a student should be able to: (a) apply for engineering/ managerial positions in oil and gas sector companies with an added advantage of having the exposure to such customised course curriculum; (b) exposure to acquire skill sets to handle projects/ design aspects / operations & maintenance relating to distribution of pressurised/ compressed/ liquefied natural gas; (c) understand literature of scientific practices relating to natural gas sector and petroleum industry and investigate research problems; and (d) carry out advanced assignments and projects at the industry/ university level in view of the societal importance of the energy sector. 4. CURRICULUM CONTENT The curriculum has two modules. The first module focusses on City Gas Distribution (GGD), and the second module focusses on the Liquefied Natural Gas. A topic wise list is below: i. Introduction – Energy sector overview – Natural gas (value chain, verticals, and commercial aspects) ii. City Gas Distribution (CGD) & Compressed Natural Gas (CNG): Technology & operations – Global perspective versus India's position – Environmental perspectives – Industry structure and government policies – Project development and execution – Design fundamentals – Asset integrity management – Operation, maintenance, and safety iii. Liquefied Natural Gas (LNG) – Global perspective versus India's position – Environmental perspectives – Gas value chain – Technology and process operations – Marine and non-marine facilities – Terminal operations and regasification – Trade and business 5. TEACHING AND LEARNING STRATEGY The course will primarily entail discussions and case studies explained by MS PowerPoint presentations. The presentations will be uploaded to SNU Blackboard Learn+ platform before the class, so that the students access it and come prepared with questions. Certain case studies will also involve demonstration of concepts by videos. Additional reading material will also be uploaded for the students to reinforce the concepts taught in the class. Depending on available time and convenience, on-site visits may be arranged to visualise practical aspects of the theoretical lectures.

A quantitative introduction to the theoretical and physical principles in fluid mechanics that are of fundamental importance to chemical engineers. The course is intended to be a first course in fluid mechanics for undergraduate 2nd year students in chemical engineering. The course will begin by introducing the necessary fundamental concepts of fluid flow, and proceed to cover both macroscopic (i.e. integral balances) and microscopic (i.e. differential balances) approaches to analyse various fluid ow phenomena encountered in chemical engineering applications. Some specific applications that will be covered in detail are: Pipe flows, fittings and friction factor charts Fow past immersed bodies: drag forces, settling Flow through packed beds and fluidized beds Fluid transportation (pumps, compressors and valves) Flow measurement techniques, and Agitation and mixing
