• Application of t-shaped trough dry-gas sealing to cycle hydrogen compressor
  形槽干气密封在循环氢压缩机中的应用
• A hydrogen consumption model of the hvdrotreating units has been developed . it can be used for design problems such as predicting the concentration of the cycled hydrogen
  并且开发了一个实用的加氢装置氢耗模拟模型，该模型可进行设计型计算预测装置循环氢浓度等。
• The results showed that : ( 1 ) the application of the above optimization method is feasible in the process of vacuum residue hydrotreating . ( 2 ) shaft power is a small part in the operation fees of the hydrogen system and has little influence on the optimization results . ( 3 ) vent should be decreased to reduce energy consumption because of the high concentration of the cycle hydrogen after rebuilding of the unit
  在pc-133微机上进行了模拟和优化计算，结果表明：(1)以复合形法为核心的可行路径序贯模块法在重油加氢过程中的应用是可行的；(2)压缩机轴功率在重油加氢的氢气系统操作费用中所占比例较小，对优化结果影响不大；(3)装置经过技术改造后循环氢纯度过高，可以减少放空以节省能耗；(4)建立的氢耗模型能够可靠地计算现有装置的循环氢浓度、溶解氢总量和装置氢耗量。
• The method of optimization is the complex method . the objective function is the opration expenses of the hydrogen system . there were six decisive variables : the pressure and temperature of the high-pressure separator of vrds, gas ration to the prism unit from vrds unit and ssot unit, the pressure of the high-pressure separator of ssot and the entrance pressure of the cycle hydrogen compressor
  优化问题以氢气系统的运行费用函数作为目标函数，选择了6个决策变量，分别为：vrds高压分离器压力、温度、vrds和ssot装置排入prism的氢气量、ssot高压分离器压力和循环氢压缩机入口压力。
