    摘要： A process for desulfurizing a crude hydrocarbon composition, such as diesel or kerosine, wherein the process comprises the following steps:
    a) providing an oxidized crude hydrocarbon composition containing at least one oxidized sulfur containing compound,
    b) subjecting the oxidized crude hydrocarbon composition provided in step a) to a liquid-liquid extraction with an extracting agent so as to obtain an extract being enriched in the at least one oxidized sulfur containing compound and a raffinate being depleted in the at least one oxidized sulfur containing compound,
    c) washing the raffinate obtained in step b) with a washing agent so as to remove remaining extracting agent from the raffinate so as to obtain a desulfurized hydrocarbon composition and a mixture of washing agent and extracting agent,
    d) subjecting the extract obtained in step b) to at least one purification step so as to obtain purified extracting agent and a waste composition, wherein the purified extracting agent is at least partially recycled into step b), and
    e) subjecting the mixture of washing agent and extracting agent obtained in step c) to a multi-step evaporation for separating the extracting agent from the washing agent so as to obtain purified washing agent, wherein the purified washing agent is at least partially recycled into step c), and wherein the multi-step evaporation comprises at least two subsequent evaporation steps, wherein the first evaporation step is performed at a higher pressure than the at least one subsequent evaporation step.
