| 1. | Residue and vapour are withdrawn continuously from the boiler . 残液和蒸气不断从再沸器抽出。 |
| 2. | Azeotropic distillation column reboiler 共沸蒸馏塔再沸器 |
| 3. | Nationalizing of gv quipment for 300 thousands ton synthetic ammonia for guang chou petroleum factory 6 .广州石化总厂30万吨合成氨装置gv再沸器国产化生产。 |
| 4. | The steam leakage was occurred on the welding zone of the tube sheet of the austenitic stainless steel heat exchanger 摘要在奥氏体不锈钢制再沸器的上管板与壳程筒体焊接的管板一侧发生蒸气泄漏。 |
| 5. | 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。 |
| 6. | 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。 |
| 7. | 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。 |
| 8. | By means of the chemical composition analysis , mechanical property testing and macro - microstructure examination , efm calculation and vibration testing , materials and working process are analyzed comprehensitly 采用化学成分分析、力学性能测定、宏、微观检验、有限元应力计算及振动测试等方法对再沸器的材料、加工工艺和工作状况进行了综合分析。 |
| 9. | 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。 |
