FEED STOCK HYDRAULIC TREATMENT WITH RANGE OF GASOIL BOILING TEMPERATURES Russian patent published in 2015 - IPC C10G65/04 C10G45/64 C10G45/08 C10G47/18 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the method of HC feed stock treatment including: mixing of mineral HC feed stock with boiling point T5 at least about 340°C and sulphur content from 200 to 20000 wppm, with output flow of the conversion stage with sulphur content about 50 wppm or below, with production of the mixed HC feed stock; hydraulic cleaning of the mixed HC feed stock at the hydraulic cleaning stage by the mixed HC feed stock treatment using the hydraulic cleaning catalyst under the hydraulic cleaning conditions including temperature from 260°C (500°F) to 427°C (800°F), total pressure from 3.4 MPa(a) (500 psig) to 20.7 MPa(a) (3000 psig) and liquid hourly space velocity (LHSV) from 0.3 h^-1 to 5.0 h^-1, with production of the hydraulically cleaned output flow with sulphur content about 50 wppm or below; separation to cuts of the hydraulically cleaned output flow with production of at least kerosene cut with sulphur content about 10 wppm or below, diesel cut with sulphur content about 20 wppm or below and bottom cut with boiling point T5 at least 355°C; at that the boiling point profile of the hydraulically cleaned output flow corresponds to at least appr. 40% of conversion of HC feed stock relatively to conversion start, corresponding to boiling point T5 of the bottom cut, and conversion of part of the bottom cut at the conversion stage by the treatment using the dewaxing catalyst at the conversion conditions including temperature from 200°C to 450°C, total pressure from 0.5 MPa(a) (5 barg) to 30 MPa(a) (300 barg) and LHSV from 0.05 h^-1 to 10 h^-1, with production of the output flow of the conversion stage.

EFFECT: method ensures diesel fuel production with low sulphur content.
