Summary: | The seam gas is used , in its region of production, in a pre-refining unit for crude petroleum, the treatment being a catalytic stage of hydrotreatment, hydroconversion or hydrocracking, to produce a pre-refined product for further refining in a separated and distant refinery. A purified seam gas, G, is used in a pre-refining unit, in which (1) a fraction, G1, of the gas is converted to H2; (2) a fluid crude petrol of flow point less than or equal to 10degreesC, P1, is selected and provided by piping and/or tanker conveyance; and (3) the charge, alone or mixed with other fractions, is treated in an installation for hydrotreatment (HDT, RHDT), hydroconversion (HDC, RHDC) or hydrocracking (HDK), the fraction for treatment comprising mainly compounds of boiling points greater than 343degreesC , to produce a pre-refined crude, PA, which is directed to a separate refinery distant from the installation. Independent claims are also included for the pre-refining process and the installation. |
