摘要
以扬子石化-扬州化工园区的烯烃输送管道为例,分析了环境污染和安全风险因素,提出了控制废气、废水、固体废物、噪声等污染物的有效方法。工程建设参照油气管道行业的相关标准规范执行,采取提高管道设计系数、选用高质量钢管以及性能优良的防腐层等措施确保管道的本质安全;确定合理的安全间距以减少对沿线人员和设施的影响;两根管道同沟敷设时,在同一管沟内分层布置以减少对当地行政规划的影响;严格控制管道焊接、检验、清管、试压等环节的施工质量;设置RTU截断阀室以减少事故状态下的环境污染和经济损失。同时,总结了管道运营期间的安全要点,提出了防范措施。
Taking the Yangtze Petrochemical Company-Yangzhou Petrochemical Park Olefin Pipeline as an example,the factors in environmental pollution and safety risk were analyzed,and effective methods to deal with waste gas,waste water,solid waste and noise were proposed. The construction of whole project was under the relative industry standards and codes. Improving design coefficient,selecting high-quality steel pipe and coating is necessary to assure pipeline safety. Determining reasonable safety interval of pipeline is suitable to eliminate the inconvenience for persons and facilities. Two pipelines were designed to the laying-in-one-ditch (the propelyene pipeline was laid at the bottom of ditch,the ethene pipeline was laid at the top of ditch,the longitudinal net space of the two pipelines was about 1.7 m and the vertical net space of the two pipelines was about 1.0 m). Construction links in welding,inspection,pigging and hydrotest were under a closed monitoring. RTU block valve chamber was set up to avoid the pollution and economic loss in case of an accident. Key factors and measures during pipeline operation are summarized.
