vacuum residue meaning in Chinese
减压渣油
Examples
- Development of vacuum residue visbreaking process with hydrogen donors
加供氢剂的减压渣油减粘裂化工艺的开发 - Standard test method for boiling point distribution of samples with residues such as crude oils and atmospheric and vacuum residues by high temperature gas chromatography
用高温气相色谱法测定带有类似原油和大气以及真空残留物的样品的沸点分布的标准试验方法 - 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。
