摘要：The risk and thermal safety characteristics of GX kerosene,HX kerosene and WX kerosene are ***,the explosion lower limits of three kinds of kerosene steams are tested by using the self-made explosion limit measuring *** differential scanning calorimeter(DSC)is employed to perform linear heating experiment on kerosene to analyze its thermal decomposition *** pyrolysis kinetic parameters of three kinds of kerosene are calculated based on the thermal dynamic *** experimental results show that the flash point and lower explosion limit of GX kerosene are relatively *** DSC test shows that the lowest initial decomposition temperature of HX kerosene is 116.5℃.According to pyrolysis kinetics calculation,the T_(D24) and apparent activation energy of HX kerosene are the *** test shows that GX kerosene has the worst thermal stability under the adiabatic *** high temperature stabilities of the three kinds of kerosene all meet the *** the whole,GX kerosene has the highest hazard,and HX kerosene has the lowest thermal *** accumulation of heat should be prevented during the storage and transportation of *** study provides the crucial safety characteristics data of coal-based aerospace kerosene-based,and provides technical support for engine reliability growth and performance improvement.

摘要：为了保证城市LNG加注站真空绝热管道在运行过程中的安全性和连续性,结合红外热像测温原理,以管道表面漏热量为保冷性能评估的基本方法,根据管道表面对流传热和辐射传热漏热量对其保冷性能进行评估。在此基础上,基于图像处理软件OpenCv和编程软件C++联合设计了工程应用型的管道保冷性能评估软件,实现了对在役管道非接触式保冷性能评估。

摘要：川东地区气田步入中后期开发阶段,净化装置长期处于低负荷运行状态,运行参数偏离设计值,造成净化效果不佳、单位操作成本增加等问题。利用Pro Max流程模拟软件对净化装置脱硫工艺进行了模拟计算,针对胺液循环量、吸收塔塔板数、吸收塔压力、贫液进口温度四个因素分别进行了单因素和多因素敏感性分析。采用正交实验法进行实验设计,完成净化效果和能耗的影响分析,利用SPSS进行实验数据的极差和方差分析,找出各因素对实验结果的影响显著性,并提出了净化装置的优化方案。
