Estimate the hydrogen consumption required to completely remove the sulfur from a hydrotreater feedstock and to reduce the nitrogen content of the product to 15 ppm by weight. The 48.5 °API naphtha feedstock to the hydrotreater contains 0.62% sulfur, 0.15% nitrogen, 0.09% oxygen by weight. You should assume that oxygen species would react with hydrogen first for complete removal of oxygen. Indicate any other assumption you would like to make about your calculations.
