Sinopec Corp. Jiujiang Petrochemical Branch Company addressed the technical problem of high failure rate of large-scale chemical fertilizer plant gasifier burners and actively carried out the “tackling operation cycle of gasifier burners†technology and achieved good results. At present, chemical fertilizer plant gasifier A furnace burner continuously operates for more than 2400 hours, ensuring the continuous, stable and efficient operation of large-scale fertilizer plant.
Since the beginning of this year, in order to reduce the influence of the viscosity of gasified raw material de-oiled asphalt on the atomization performance of gasification nozzles, Jiujiang Petrochemical Company proposed a technical measure for blending partially dry gas. When the de-oiled asphalt is atomized, part of the dry gas is burned, the company's process parameters are normal, the burning of the refractory bricks in the gasifier wall is significantly reduced by the flame, and the effective gas composition of the synthesis process gas can reach about 95%. Subsequent processes have no negative impact. The dry gas blending process not only optimizes the comprehensive utilization of the gas in the refinery, reduces the production cost of the chemical fertilizer, but also makes the raw material components of the ammonia plant lighter, and effectively improves the operating conditions of the gasifier.
In addition, the company's technical transformation of the liquefied gas pipeline, the use of cut-off valve group to replace the original one-way valve, which can effectively prevent the liquefied gas through the one-way valve throttle throttling and liquefaction gas liquefaction, to avoid the gasifier burner Local overheating causes damage, effectively reducing the equipment failure rate and ensuring long-term operation of the gasifier burner.
