摘要:

管道是化工生产的“血管”,其服役工况往往伴随着高温、高压(差)、高流速等运行条件,含气液相变气-液-固三相局部流动条件,以及临氢、高氯、高硫及高酸的强腐蚀环境。输送介质理化性质的多样性、服役环境的严苛性以及损伤失效机理的复杂性对化工管道运输提出了更高的要求。文章主要回顾了国内外化工管道运输技术进展,结合高温高压工艺参数以及腐蚀、临氢、含固多相组分等介质特点,分析了不同性质输送介质给化工管道运输带来的技术挑战,从严苛复杂环境下管道设计理论、材料和监检测技术研发、管道智能化运维、管道标准规范建设方面提出了化工管道运输需要重点发展的方向,以期提升化工管道运输水平,满足新形势下化工管道运输的需求。

Abstract:

Pipelines are the ‘blood vessels’ of chemical production, often operating under conditions of high temperature, high pressure (differential), and high flow rates. These conditions include gas-liquid phase changes with local three-phase (gas-liquid-solid) flow, as well as environments characterized by the presence of hydrogen, high chlorine, high sulfur, and high acidity, which are highly corrosive. The diversity of the physical and chemical properties of the transported media, the harshness of the service environments, and the complexity of the damage and failure mechanisms pose greater demands on chemical pipeline transportation. This article mainly reviews the progress of chemical pipeline transportation technology both domestically and internationally. By integrating high-temperature and high-pressure process parameters, as well as the characteristics of corrosive, hydrogen-prone, and solid-containing multiphase media, it analyzes the technical challenges brought to chemical pipeline transportation by different types of media. From the perspective of pipeline design theory, material and monitoring technology research and development, intelligent pipeline operation and maintenance, and the construction of pipeline standards and specifications in harsh and complex environments, the article proposes key directions for the development of chemical pipeline transportation. The aim is to enhance the level of chemical pipeline transportation and meet the demands of chemical pipeline transportation under new circumstances.
