Title:
精留を伴うストリッピングによる中間分留を含む、中間留出物を水素化処理するための2段プロセス
Document Type and Number:
Japanese Patent JP2005509727
Kind Code:
A
Abstract:
A process for hydrotreatment of a hydrocarbon feed comprises at least two reaction steps with intermediate fractionation of the effluent from the first step to eliminate unwanted impurities for the catalyst of the second step and to produce a desulphurized light liquid fraction. The intermediate fractionation comprises stripping the liquid effluent from the first step using low pressure hydrogen with rectification of the stripping vapours using a substantially desulphurized liquid reflux. The conditions for said fractionation and for the first hydrotreatment step can produce a substantially desulphurized light liquid fraction which is not supplied to the second step.
