Natural gas processing plants in India especially in the western part of the country have a very high presence off-shore when compared to the Eastern parts. ONGC Hazira, Gujarat is selected for the flowsheet development and simulation with optimization of a natural gas processing plant using Aspen-Hysys as the Hazira plant is India's largest gas-processing facility and a critical supplier of the fuel to domestic industries. Flowsheet development and simulation of 73 MMSCFD natural gas producing Hazira plant was done by Aspen-Hysys. The simulation was performed based on factors like design and physical property data of the plant. Then optimization was done to minimize the cost by controlling the stream flowrates and energy duties and hence maximizing the profit. Profit generated was taken as the objective function calculated by the difference of revenue obtained from Liquid natural gas and Liquefied Petroleum gas and the condenser, re-boiler and cooler duty expenses. Optimizer tool embedded in Aspen-Hysys is used to optimize this process which resulted in nearly 10% increase in the profit with minimal changes in the compositions of the final product.
