南帕斯凝析油卸船的安全措施

针对南帕斯凝析油接卸作业过程中易产生较高含量有毒气体的问题,分析了凝析油的基本性质和硫化物分布情况,以识别其有毒气体成分.描述了接卸作业前和码头接卸作业两个阶段的注意事项:接卸作业前应对各个作业环节进行风险识别,制定应急方案,并确保设备完整；码头接卸作业前先进行作业准备,划定作业警戒区且保证消防通道畅通,接卸作业时,持续进行硫化氢检测,接卸作业后,及时对管道进行置换.最后,指出检尺口和卸船舱口为主要泄漏风险部位,提出了解决措施.

Safety measures for ship unloading of South Pars condensate

High content toxic gas easily occurs in the unloading operation process for South Pars condensate.This paper analyzes the basic properties of condensate and distribution situation of sulfides,and identifies the composition of toxic gas.It describes the matters needed to be attended for initial unloading and unloading operation in terminal in details.Before unloading operation,risk identification for all operation links should be carried out,emergency response scheme and the integrity of equipments are necessary.Before unloading operation,operation preparation shall be carried out first,and an operation alert area must be set up to provide an unblocked fire passage.When unloading operation begins,monitoring for hydrogen sulfide should be kept,and after the unloading operation,timely replacement of the pipeline should be done.It is pointed out that the inspection port and unloading hatch are possible leakage areas.It is suggested that inspecting hydrogen sulfide and mercaptan should be made for other products oil.Special measures for malodor prevention in terminal area are given.
