摘要:
为明确紧急关断（emergency shutdown,ESD）系统对天然气泄漏灾变危险载荷发展特性的影响，以天然气开发地面处理工艺系统为研究对象，建立天然气泄漏灾变事故后果预测评估模型，研究ESD系统响应下天然气的空间运移和燃爆行为，并与ESD系统未响应时的预测结果进行对比。研究结果表明：ESD系统有助于降低气体泄漏速率，从而影响泄漏天然气的扩散行为及其燃爆特性，大幅减缓窒息灾害效应并阻断天然气泄漏事故的灾变升级，因此，评估天然气泄漏灾变事故后果时应考虑ESD系统的响应。研究结果可为油气处理作业防灾减灾措施的设计与优化提供参考。
Abstract:
In order to clarify the influence of emergency shutdown (ESD) system on the hazardous load development characteristics in the natural gas leakage catastrophe,a prediction and evaluation model for the accident consequence of natural gas leakage catastrophe was established by taking the ground processing system of natural gas development as the research object.The spatial migration and explosion behavior of natural gas under the response of ESD system were studied and compared with the predicted results when the ESD system was not responsive.The results show that ESD system helps to reduce the gas leakage rate,thus influence the dispersion behavior and explosion characteristics of the leaked natural gas,and may even completely eliminate the suffocation impact and block the catastrophic escalation of natural gas leakage accident.The response of ESD system should be considered when assessing the accident consequence of natural gas leakage catastrophe.The research results can provide reference for the design and optimization of disaster prevention and mitigation measures for oil and gas processing operations.
