FIELD: mining.
SUBSTANCE: invention can be implemented at withdrawing purified gas G from reservoir, where a) gas flow of hydrogen from at least converted fraction G1 of said gas G used in installation (I) for processing hydrocarbons and usually another fraction G2 of said gas G are used as fuel in said installation (I) for hydrocarbon processing; b) natural liquid transportable crude oil P1 is withdrawn at temperature of solidifying 0°C or less including vacuum residue with contents of sulphur over 1% of weight and is transported via not-heated pipeline or not-heated oil tanker; c) said oil P1 is processed on said installation for hydrocarbon processing (I), also said processing is performed essentially without carbon unloading, and said processing includes: at least one stage of de-sulphurisation by means of hydro-purification (HDT, RHDT) or hydro-conversion (HDC, RHDC), or hydro-cracking (HDK) of at least one fraction of oil P1; also said fraction mainly includes compositions with boiling temperature exceeding 343°C; further said stage consumes at least part of flow H2, at least one stage, which can be common with said stage of de-sulphurisation or separate from it to decrease amount of vacuum residue included into oil P1 with separation of part or total vacuum residue, not necessary with conversion of part of said vacuum residue, where complete separation of at least part of pyrobitumens of said vacuum residue is carried out with the purpose of obtaining at least one preliminary purified oil product PA including compounds produced from stage of de-sulphurisation; also said preliminary purified oil product PA in essence does not contain pyrobitumens and contains reduced amount of sulphur at least at 50%, while contents of vacuum residue with sulphur contents is over 1 wt %, which is accepted as zero or reduced at least at 15% relative to oil P1, and at least separate fraction including at least basic part of pyrobitumens, not necessary cracked and/or replenished with other fractions from P1 in form of heavy liquid fuel and/or residual oil product PB, which is liquid at temperature of environment d), said preliminary purified oil product PA is pumped to oil port as source raw material for refinery designed to be purified at refinery, which differs and is distanced from installation (I).
EFFECT: reduction of excess of sulphur containing residues of oil refinery, reduction of power and ecological costs caused by transporting of said excessive residues and by liquation and transporting of natural gas.
