Petroleum Desulfurization – Chemical production and ...

The term deep desulfurization refers to the removal of 90 to nearly 100% of the sulfur contained in the petroleum fraction. This corresponds to an average product sulfur level of 25 ppm in naphthas, 0.1 wt% in gas oils, and 0.3 wt% in residual fuel oils. These low sulfur contents are dictated by increasingly stringent government regulations.

Petroleum Desulfurization – Chemical production and ...

Published January 1969. This report is concerned with technology and costs for the desulfurization of petroleum stocks. Although the hydrodesulfurization of light and middle distillates such as gasoline, naphtha, kerosene, and gas oil is also evaluated, the emphasis here is on sulfur removal from the resid- ual fuel oil where there is a growing concern today
