The document discusses efficiency improvements for processing units at ONGC's Uran plant in India. It provides background on ONGC and describes the various units at the Uran plant. The objective is to study the processes, find recovery factors for key units like LPG and EPRU, observe efficiency changes, and suggest solutions. Graphs show recovery factors and production for units over time. Recommendations include periodic maintenance, improved software/training, and replacing gas turbines with electric motors. Cost-benefit analysis estimates annual profit of over 23 crore rupees from improved maintenance of heat exchangers.
