| 1. | Azeotropic distillation column reboiler 共沸蒸馏塔再沸器 |
| 2. | In place of the reboiler , a heating coil may be placed in the bottom of the column to generate vapor from the pool of liquid there 例如可以在精馏塔的底部安装一个加热盘管代替再沸器,加热釜液产生蒸汽。 |
| 3. | Reboiler is the common heat exchanger in the petrochemical industry and bundle leakage caused by corrosion during operation is the most popular failure 摘要再沸器是石油化工等流程工业常用的换热设备,使用过程中最易产生的失效形式为管束腐蚀引起?漏。 |
| 4. | The results showed that the heat taken from the feed section should be the same as in the double tower case , and the added reboiler should be located in the middle of the desorption section 对新的催化裂化吸收-解吸单塔流程工艺条件的模拟研究结果表明,进料取热应和双塔流程相同,而加热板宜选在解吸段的中部。 |
| 5. | Several types of materials were tested and suitable materials were provided for the low transformation reboiler , which is important in the research for increasing service life of reboilers 针对低变气再沸器的具体使用情况,分析了失效的原因,对多种材料进行性能对比试验研究,选用合适的再沸器材料,对延长再沸器的使用寿命具有重要的研究价值。 |
| 6. | Experimental results showed that the mixed solvents at the bottom and the product at the top of the column can be removed simultaneously for a long period of time in the middle - vessel batch distillation , and thus it requires a much smaller reboiler compared with a regular column 实验结果表明,带有中间贮罐的间歇萃取精馏过程在很长一段时间内具有塔顶采出产品,同时具有在塔底采出混和溶剂的特点,因而与常规间歇萃取精馏过程相比,带有中间贮罐塔时间精馏技术需要的再沸器体积大大减小。 |
| 7. | In the first place , with the comparison among several sorts of configurations between the asu and gas turbine , ep - asu is theoretically proved to have better overall igcc power output , overall efficiency and net cost of power generation than lp - asu . furthermore , the pressure ratio of the asu and the temperature diffenrence of the main reboiler / condencer are found to be the two key factors which affect the power consumption by the asu 具体来说,本文首先通过对空分系统与燃气轮机配置方案的深入研究和对比,从理论上说明了ep - asu与lp - asu相比能耗更低、投资更省、效率更高;并进一步得出空分压比和空分系统的主冷温差是影响空分系统能耗的关键性因素。 |
