Title:
DIRECT DESULFURIZATION METHOD AND HEAVY CARBOHYDRATE REDUCED CRUDE OIL
Document Type and Number:
Japanese Patent JP2017226799
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a direct desulfurization method capable of reducing severity of operation conditions.SOLUTION: There is provided a direct desulfurization method having a heat stirring process (1) for mixing a crude oil sludge (A) and a crude oil (B) so that percentage of the crude oil sludge (A) to total of the crude oil sludge (A) and the crude oil (B) is 5 to 90 mass%, then heat stirring the mixture of the crude oil sludge (A) and the crude oil (B) at 40 to 95°C to obtain a heat stirring treated article of the crude oil sludge (A) and the crude oil (B), a heavy hydrocarbon reducing process (1) for removing or reducing polymer hydrocarbon with molecular weight of 2500 to 15000 from the heat stirring treated article, a crude oil mixing process (1) for mixing the heavy hydrocarbon reducing crude oil (1) with a crude oil (C) to obtain a mixed crude oil (D), an atmospheric distillation process (1) for separating an atmospheric pressure distillate component from the mixed crude oil (D) by an atmospheric pressure distillation to obtain an atmospheric pressure residue oil (1) and a direct desulfurization process (1) for conducting a direct desulfurization treatment by using the atmospheric residue oil (1) as a direct desulfurization treatment.SELECTED DRAWING: None
