Abstract (en)
The desulfurization of a hydrocarbon feed with a boiling range of 150-450[deg]C and a sulfur content of up to 3% comprises adsorbing sulfur compounds from the feed in an adsorption column that acts as a simulated moving bed, distilling the raffinate to produce a desulfurized gas oil stream and a desorbent recycle stream for the adsorption column, and distilling the extract to produce a sulfur-containing impurity stream and a desorbent recycle stream for the adsorption column. The desulfurization of a hydrocarbon feed with a boiling range of 150-450[deg]C and a sulfur content of up to 3% comprises adsorbing sulfur compounds from the feed (1) in an adsorption column (2) that acts as a simulated moving bed and comprises several adsorbent beds with different selectivities for sulfurized and unsulfurized hydrocarbons and comprises a first zone between a inlet for desorbent (9b) and an outlet for extract (4), a second zone between the extract outlet and feed inlet, a third zone between the feed inlet and an outlet for raffinate (3) and a fourth zone between the raffinate outlet and the desorbent inlet, distilling the raffinate in a distillation column (5) to produce a desulfurized gas oil stream (8) and a desorbent recycle stream (9) for the adsorption column, and distilling the extract in a distillation column (6) to produce a sulfur-containing impurity stream (10) and a desorbent recycle stream (11) for the adsorption column.
