By modifying the process conditions of the CO 2 flash column, the CO 2 flashed is increased in volume, and the overall capability to meet contingency of the whole unit is improved. 通过对CO2闪蒸塔工艺操作条件的改进,增加了CO2闪蒸量,提高了全装置的整体应变能力。
To fundamentally solve the problem of corrosion to furnace liner by intensified metallurgy, the idea of non-contact metallurgy was put forward. The flash smelting method of central swirling column was described, and the basic design of swirl nozzle and computer simulation experiment was introduced. 为根本解决强化冶金对炉衬的腐蚀,提出了“非接触冶金”的思路,描述了中心旋涡柱闪速熔炼方法,并介绍了旋涡喷嘴基本设计及计算机仿真实验。
And then two individual compounds were isolated out of the above spots using the dry column chromatography, flash chromatography and the others. 在此基础上用干柱层析(drycolumnchromatography)、闪式柱层析(flashchromatography)等方法进行分离,从藏药赛朱的特征斑点中分离得到了2个化合物。
For lowering the steam consumption, the method of recovering heat by setting up a flash tank at the bottom of the saponification column is simple and effective. 为降低我国小型PO装置的蒸汽消耗,设置皂化塔釜液闪蒸罐回收热量是简单和有效的。
Design schemes for prefractionator pressurizing, flash column atmospheric distillation, atmospheric column pressurizing and atmospheric distillation have been compared and analyzed taking a large scale crude oil process engineering project as example, and the design scheme of atmospheric and vacuum distillation unit has been finally determined. 以某大型原油处理工程项目为例,对初馏塔加压方案、闪蒸塔常压方案、常压塔加压方案和常压方案进行了对比分析,最终确定常减压蒸馏装置设计方案。
Accompanying with the salt deposition, there were inflexible adjustment of fractionator top temperatures, cavitation in top circulating reflux pump, production of light gas oil with substandard flash point as well as difficult drawing out from the column, etc. 结盐时伴随有塔顶温度调整不灵活,塔顶循环回流泵抽空和轻柴油闪点不合格和抽出困难等现象。
The whole work is described as follow: First, Pro/ II with Provision was harnessed as the process simulation engine. Sequential modular was applied on flash column, prefractionator, atmospheric column and vacuum column for steady state simulation. 主要研究工作如下:第一,以PRO/Ⅱ作为流程模拟工作的工具,应用序贯模块法对三套常减压装置的闪蒸塔、初馏塔、常压塔与减压塔分别进行了稳态模拟。
