Natural Gas Engineering

Indian Institute of Technology Guwahati and NPTEL via Swayam


The field of natural gas engineering is very much important for petroleum engineers specializing in gas processing technology. The course outlines an optimal balance between natural gas production, natural gas processing and gas transportation. An extensive treatise on natural gas engineering, both upstream and gas refining processes with key equipment and facility design will be covered. This course will also highlight the current status of production of natural gas through unconventional sources/technics and the applications of natural gas.INTENDED AUDIENCE :Under graduate and post graduate students professional practitioner in the discipline of Chemical Engineering.
