Abstract
Przedmiotem zgłoszenia jest sposób dekontaminacji fazy gazowej w zbiornikach ropy naftowej, realizowany w finalnym etapie procesu czyszczenia zbiornika, po zakończeniu recyrkulacji czynnika myjącego oraz separacji fazy węglowodorowej, polegający na przemywaniu całej objętości zbiornika naprzemiennie niepolarnym i polarnym czynnikiem dekontaminujących. Przy czym w pierwszym stadium przemywa się fazę gazową w zbiorniku, silnie rozproszonym strumieniem niepolarnego medium dekontaminującego, mającego postać średniej frakcji naftowej, a następnie wymywa się substancje szkodliwe, wraz z resztkowym osadem dennym i pozostałościami niepolarnego medium dekontaminującego, silnym strumieniem wody, w roli polarnego medium dekontaminującego. Ponadto pochodząca z przerobu ropy naftowej i/lub świeżego oleju bazowego i/lub regeneracji oleju odpadowego, średnia frakcja naftowa ma lepkość kinematyczną 0,8 - 14 mm<sup>2</sup>/s w temperaturze 100°C i cechuje się następującymi temperaturami wrzenia, nie więcej niż 5% destyluje do 200°C oraz nie mniej niż 90% destyluje do 540°C. Przemywanie określonymi porcjami mediów dekontaminujących, o temperaturze od 30 do 65°C powtarza się sekwencyjnie, aż do uzyskania w zbiorniku zamierzonego obniżenia poziomu stężenia lekkich węglowodorów, takich jak benzen, toluen, ksyleny węglowodory C5+ i siarkowodoru. Przemywanie fazy gazowej i osadu dennego prowadzi się w temperaturze od 25 do 65°C w zbiorniku czyszczonym, stosując w pojedynczym cyklu przemywania od 1% m/m do 50% m/m medium niepolarnego w stosunku do oszacowanej ilości osadu w zbiorniku przed rozpoczęciem procesu dekontaminacji oraz od 1 do 20 razy więcej medium polarnego w pojedynczym cyklu przemywania w stosunku do objętości wprowadzonego w pojedynczym cyklu medium niepolarnego. Korzystnie po usunięciu zanieczyszczeń niepolarnym i polarnym medium dekontaminującym, fazę gazową poddaje się adsorpcji na złożu sorbenta stałego, poprzez cyrkulację fazy gazowej, w temperaturze od 25 do 65°C ze zbiornika przez kolumnę sorpcyjną wypełnioną złożem węgla aktywnego.The subject of the application is a method of decontaminating the gas phase in crude oil tanks, carried out in the final stage of the tank cleaning process, after the recirculation of the cleaning agent and the separation of the hydrocarbon phase, consisting in washing the entire volume of the tank alternately with a non-polar and polar decontaminating agent. In the first stage, the gas phase in the tank is washed with a highly dispersed stream of non-polar decontamination medium, in the form of a medium petroleum fraction, and then harmful substances are washed out, together with the residual bottom sediment and the remains of the non-polar decontamination medium, with a strong stream of water, acting as a polar decontamination medium. Moreover, derived from the processing of crude oil and/or fresh base oil and/or the regeneration of waste oil, the medium crude oil fraction has a kinematic viscosity of 0.8 - 14 mm<sup>2</sup>/s at 100°C and is characterized by the following temperatures boiling, not more than 5% distils to 200°C and not less than 90% distils to 540°C. Washing with specific portions of decontamination media at temperatures from 30 to 65°C is repeated sequentially until the desired reduction in the concentration of light hydrocarbons in the tank, such as benzene, toluene, xylenes, C5+ hydrocarbons and hydrogen sulphide. Washing of the gas phase and bottom sediment is carried out at a temperature of 25 to 65°C in the cleaned tank, using in a single washing cycle from 1% m/m to 50% m/m of a non-polar medium in relation to the estimated amount of sediment in the tank before the start of the process decontamination and from 1 to 20 times more polar medium in a single washing cycle in relation to the volume of non-polar medium introduced in a single cycle. Preferably, after removing impurities with a non-polar and polar decontamination medium, the gaseous phase is adsorbed onto the solid sorbent bed by circulating the gaseous phase at a temperature from 25 to 65°C from the tank through a sorption column filled with an activated carbon bed.
