Abstract: In the process design of petrochemical plants, it is a common practice to centrally incinerate and discharge excess or emergency emissions of combustible gases (such as hydrogen, natural gas, etc.). However, the elevated flare at the end of the process often poses difficulties for engineering installation, construction, maintenance, and repair due to its high height. Among these, the replacement of the flare head of the elevated flare often becomes a control engineering task for plant shutdown and overhaul due to the high construction difficulty and risk.This article comprehensively controls the risks of the torch head lifting process through the design of the lifting process for replacing and lifting the torch head, as well as the calculation of the stress conditions of the lifting mast, cables, holding pole winch, pulley block, and steel wire rope, achieving the goal of safe and smooth lifting and successfully completing the replacement of the torch head.
