中文摘要:随着油气领域不断发展,含硫天然气处理技术的日益成熟,极大推动了含硫气田的开发。鉴于各国工业对硫黄的需求增加和大气污染控制标准日益提高,硫黄产品回收技术得到大力发展。相比固体硫黄交易,液体硫黄输送可省去上游硫黄固化和下游硫黄再熔的投资和运行费用,且具有运输效率高、粉尘污染少等特点,故在技术可行的前提下,可优先应用。有必要深入探讨中长距离液体硫黄管道工艺要点与模拟手段。基于液体硫黄黏温特性,结合液体硫黄输送工艺,探讨了液体硫黄管道工艺计算与分析思路,借助商业软件模拟了某液体硫黄管道稳态与瞬态输送过程,进一步揭示了液体硫黄管道的运行规律。研究结果表明:通过产品属性拟合,可借助TLNET软件进行液体硫黄输送的工艺模拟;由于液体硫黄管道输送对温度要求极高,因此线路温降曲线近乎呈直线下降趋势;较高的液体硫黄介质密度引起的水击压力较高,需在设计压力选取中进行压力裕量讨论。本研究成果可为液体硫黄管道工艺分析提供相关参考和借鉴。

 

英文摘要:
With the constant development of oil and gasfields,sulfur-containing natural gas processing technology is increasingly mature,which greatly promotes the development of sulfur-containing gas fields. In view of the increasing demand for sulfur from various industries in each country and the increasing

control over air pollution,sulfur product recovery technology has been greatly developed.Compared with solid sulfu rtrading,liquid sulfur transportation can save investment and running costs of upstream sulfur curing and downstream sulfur remelting,and has the advantages of high transportation efficiency and less dust pollution.There fore,it can be preferentially applied when it is technically feasible.So,it is necessary to explore in depth the process points and simulation methods for long-distance liquid sulfur pipeline.Based on the viscosity-temperature characteristics of liquid sulfur and liquid sulfur transportation technology ,the process calculatipon and analysis of liquid sulfur pipeline are discussed.The steady-state and transient transmissi0n process of a liquid sulfur pipeline is simulated by commercial software to further reveal the operating rules of liquid sulfur pipeline.The results show that theTLNET software can simulate the process of liquid sulfur transportation through product property fitting.Because of the extremely high delivery temperature of the liquid sulfur pipeline,the temperature drop curve of the line is almost linearly decreasing;the higher density of the liquid sulfur medium will cause higher water hammer pressure and the design pressure shall be selected in the pressure margin discussion.The research results of this paper can provide references for the process analysis of liquid sulfur pipeline.
