| 1. | Cracking unit fractionator
裂化装置的精馏塔 |
| 2. | Heat and mass in the main fractionator are removed by the exchangers and product streams around the main fractionator
主分馏器里所有的反应物和能量都被交换器和产物蒸汽移除。 |
| 3. | All of the mass and energy in the main fractionator system are supplied to the system by the reactor and regenerator
主分馏器里所有的反应物和能量都是由反应堆和交流热换器提供的。 |
| 4. | The rundown of stripper bottom product is by level control acting on the fractionator furnace pass control valves
汽提塔底产品的排出由液位控制，该液位控制调控分馏塔加热炉通道控制阀。 |
| 5. | The system itself is inherently safe , because the converter cannot produce sufficient pressure to overpressure the main fractionator
因为转炉不能产生足够的使主交流热换器过压的压力，所以说，系统本身是固有地安全的。 |
| 6. | The effluent product in the reactor goes to the main fractionator , where the heat is removed in its various pump - around loops and initial product separation is accomplished
反应堆的流出物会进入到主分馏器，在那里，热量会被四周围各种各样的循环泵带走，从而形成最初的产物。 |
| 7. | There have long been question regarding whether or not an fcc main fractionator needs relief valve protection for anything except some smaller events , like steam ? out or fire
关于是否要fcc标准下主分馏器的的电子管来保护除了像蒸汽或炉火等一类的小事件之外的器件，已经成为了一个长期争论的问题。 |
| 8. | Definition of the multivariable control strategy has been provided in sufficient detail with emphasis on the regenerator control , cracking conversion control , pressure balance control , main fractionator bottom control and cracking yields control
从烧焦控制、裂化苛刻度控制、压力平衡控制、分馏塔底控制和裂化产率优化控制等五方面详细论述了反应-再生系统的控制策略。 |
| 9. | The industrial application showed that the key process parameters , such as the regenerator dense phase temperature and the temperature under the first tray of the fractionator bottom , etc . were obviously improved , which resulted in increasing conversion and light oil yield
工业实践表明，应用此控制明显地改善了对再生催化剂温度、分馏塔底第一层板下温度等关键工艺参数的控制，提高了装置的转化率与轻油收率。 |
| 10. | When the design pressure of the reactor / regenerator is less than or equal to the design pressure of the main fractionator , or there is some absolute mechanical limit to the regenerator pressure ( plus the static head difference between the regenerator and reactor ) that is less than the main fractionator design pressure , the units do not need large relief valves on the main fractionator
当所设计反应器或交流热换器的压力小于或等于主分馏器，又或者有些机械上无可避免的限制（还有就是两静电头的不同）小于交流热换器的压力，其时整个部件就不需要大的调剂电子管了。 |
