Corrosion And Scaling Inhibition Technology Of The Changqing First Natural Gas Plant Natural Gas Heating Furnace

The first natural gas plant of Changqing Oilfield in the production of natural gas gathering, after closure to prevent ice clogging of natural gas pipelines, the need for natural gas for heating; water jacket heater as a heater for indirect heating of natural gas, natural gas as fuel, the water jacket in the water heating, and through high-pressure hot water bath in which the natural gas pipelines over heated to the temperature specified, the process of natural gas produced in the throttle throttling does not occur when the cooling effect of ice block hydrates phenomenon; furnace is running, the long-term immersion heater coil in the hot resulting in non-current coil outer wall of water appeared more serious corrosion, increase the risk of furnace operation. In this paper, corrosion of the water heater be set to a combination of experimental and theoretical studies were analyzed to determine the gas heater corrosion, scaling mechanism and influencing factors, while identifying the natural gas furnace cleaning fluid, passive fluid formulation and daily operation of the corrosion inhibitor compound formula and the appropriate treatment program. And to develop a furnace daily operation and management program.
