摘　　要：本文简要概述了海管内生产流体因维修或防止水合物需要泄压操作时,因火炬分液罐增压泵为常温设计,无法处理泄放过程中的低温流体,因此需要操作者利用罐内加热器升温流体满足泵输送温度要求。为避免泄放低温流体体积超过火炬分液罐缓冲容积,本文创新性地提出了分级泄压的概念,既满足泵输送温度要求,又满足火炬分液罐缓冲容积要求,为后续类似项目开发提供了良好的借鉴。The article briefly introduces depressurization of the flowline may be required for maintenance and repair of the flowlines,or for melting hydrate plugs should they occur.Flare knock-out drum pumps min design temperature is ambient temperature,low temperature liquid from depressurization cannot be pumped into the production processing system for treatment directly.The liquid must be stored in the knock-out drum until its temperature increases to ambient temperature by electrical heater.Multi-stage depressurization will solve the conflict between low temperature blow-down liquid volume and flare knock-out drum surge volume,and provide reference for similar projects in the future.
