Simulation of six refinery configurations for capacities ranging between 3 and 30 MMTPA has been carried out for processing opportunity heavy crude oils: Arab Heavy and Iranian heavy for zero residue and zero fuel oil refinery. Linear programming was employed to predict yields, product properties and utility consumptions. An optimizer was used to vary selected parameters to maximize the overall profit. Economic analysis like profit/barrel of crude, requirements of capital investment, simple payback period and internal rate of return has also been carried out. The results of the study shows that refinery profit ranges from about $10 to $18 per barrel of crude depending upon throughput, crude properties and the configuration selected. It initially increases with capacity but gets stagnated at around 12 – 18 MMTPA capacity. Although, this suggests that the optimum capacity is 18 MMTPA for a grassroots refinery, other factors like simple payback favor higher capacities. A typical 30 MMTPA refinery requires a capital investment of around Rs. 25,000 – 40,000 crores with a payback period of 1.5 – 3 years. The Internal Rate of Return (IRR) is highly sensitive to crude oil and product prices. Higher capacity refineries (24-30 MMTPA) are more resistant to these variations. Generally, for a 10 times increase in capacity (from 3 to 30 MMTPA), the investment requirement increases 4-5 times, the payback period gets halved and the increase in profit/bbl is between 2 to 3 US$.
