Embodiment Construction
[0012] Further illustrate the present invention below in conjunction with accompanying drawing and a specific implementation process:
[0013] Drained 3000m 3 The oil tank is filled with oil gas with an oil gas concentration of 4%, and the oxygen concentration reaches 12% after 1-2 hours of inert replacement; at this time, the inert gas generation system is turned off, and the circulation pipeline is switched to the catalytic reaction system. The oil and gas that have been inerted first enter the heat exchanger. Before starting the catalytic reactor, use a preheater to heat the oil and gas so that the outlet temperature reaches 250-270 ° C. At this time, after the oil and gas mixture enters the catalytic reactor, the high temperature oil and gas mixture is ignited under the action of the catalyst. The high-temperature gas product after combustion enters the hot end of the heat exchanger to exchange heat with the newly entered oil and gas, and then circulates into the oil tank...
