Hydrogen consumption and the technological scheme of crude refining

Conclusions

• 1. It has been shown that the crude processing scheme has a considerable effect on the requirement of specially produced hydrogen. Hydrogen requirement is particularly high in hydrocracking processes.

• 2. With increased sulfur content in the crude, the requirement of special hydrogen is higher owing to reduced production of catalytic reforming hydrogen and increased specific consumption of hydrogen for desulfurizing.

• 3. The quality of fresh hydrogen determines the total hydrogen consumption in the process, which may be double or more the hydrogen consumption for the reaction.
