METHOD OF PROCESSING SULPHURIC GAS CONDENSATE BOILER OILS Russian patent published in 2012 - IPC C10G65/04 C10G45/04 

FIELD: oil-and-gas production.

SUBSTANCE: invention relates to processing of sulphuric gas condensate boiler oils by non-catalytic hydrovisbreaking in hydrogen-containing gas for production of hydrogenator to be subjected to separation to obtain hydrovisbreaking residue as a liquid phase and, as vapor phase, the mix of hydrogen-containing gas and fraction boiling away at below 450°C and intended for catalytic hydraulic desulfurisation on two layers of low-activity catalysts. Note here that, first layer comprises catalyst in the form of Rushig rings containing nickel and cobalt oxides in amount of 0.8-1.5 wt %, molybdenum oxide - 3.5-4.5 wt %, and aluminium oxide making the rests. Note also that second layer comprises catalyst in the form of extrudates containing nickel oxide in amount of 1.5-2.5 wt %, molybdenum oxide - 6-7 wt %, and aluminium oxide making the rest. Mind that volume ratio of the first and second catalyst layers varies from 1.0:0.6 to 1.0:1.2 to produce hydraulic desulfurization catalyst accompanied by its condensation and cooling, separation of hydrogen-containing and hydrocarbon gases and stabilisation together with hydrovisbreaking residue resulting in fraction boiling away at below 350°C and stabilised fraction boiling away at above 350°C to be used as oiler or marine fuel.

EFFECT: deeper desulfurisation of sulphuric gas condensate boiler oils, higher processe efficiency.
