Abstract
The invention relates to a process for the production of thermally-integrated hydrogen from a liquid hydrocarbon feedstock that contains sulfur-containing compounds that comprise at least one stage for heating the liquid hydrocarbon feedstock by indirect heat exchange with a hot stream, a stage for desulfurizing the heated hydrocarbon feedstock, a stage for evaporating the desulfurized hydrocarbon feedstock by indirect heat exchange with the hot stream that exits from the autothermal reformer, a stage for autothermal reforming of the hydrocarbon feedstock, and a stage wherein the carbon monoxide content in the hydrogen-rich gas that is produced is reduced in a reactor for converting carbon monoxide with water. The invention also relates to the hydrogen production installation that corresponds to this process.
