摘要: 高压加氢裂化装置循环氢加热炉炉管设计寿命为10万h,但由于工况不同,炉管的更换周期与设计寿命会有很大差距。某石化公司高压加氢装置循环氢加热炉炉管已累计运行14万h。通过现场检测以及对炉管样品进行化学成分分析和力学性能试验,对炉管剩余寿命进行评估,进而制定了合理的运行操作指标,并确定了有科学依据的炉管更换时间。此外,还对今后装置的安全运行提出了指导性意见。

Abstract: The designed service life of the furnace tubes in recycle hydrogen furnace in high-pressure hydrocracking unit is generally 100,000 hours. However, due to different working conditions, the replacement cycle of the furnace tubes may differ greatly from the designed service life. The furnace tubes in recycle hydrogen furnace in the high-pressure hydrogenation unit of certain petrochemical company has been running for a total of 140,000 hours. In this paper, the remaining service life of the furnace tubes is evaluated through on-site testing, chemical composition analysis and mechanical property test of the furnace tube samples, and then reasonable operation indexes were set and scientific arrangement of furnace tube replacement time was determined. In addition, guidance was presented for the safe operation of the unit in the future.
