The results of numerical simulation suggest that the demisting efficiency increases as droplet diameter and gas velocity increasing and decreases as the mist eliminator plate spacing reducing, and the efficiency of arc-shaped plate with barb mist eliminator is higher than that of polyline-shaped plate mist eliminator. Droplet with a diameter under 20 mm is of low demisting efficiency.

数值分析表明：除雾效率随液滴直径的增大而增大，随进气速度的增大而增大，随除雾器叶片间距的增大而降低；带倒钩的弧形板除雾器比折形板除雾器的除雾效率高；粒径小于20 mm的小液滴脱除效率较低。

This article describes the present situation of high-pressure and low-pressure flash tank ,gas-liguid separator and purified gas filter.

详细介绍了聚乙二醇二甲醚脱硫脱碳装置中脱硫富液、脱碳富液的高、低压闪蒸槽以及气液分离器和精制气气体过滤器的生产现状，分析了这些设备出现瓶颈的原因，同时提出了相应的扩能改造的基本思路和方法，最后总结了改造的效果。

Operation analysis and investigation show that it is caused by the inappropriate design of hot vapor bypass control system, so the revamping has been carried out as follows: The diameter of hot vapor bypass pipeline has been enlarged from DN 40 mm to 80 mm, and the pressure difference of hot vapor bypass adjusting valve decreased from 50 kPa to 35 kPa; A vent pipeline for non-condensable gas fro.

改造的措施主要有：增大了热旁路管道的直径(由DN40mm增大到DN80mm)，并降低了热旁路调节阀的压差取值(由50kPa降低到35kPa)；增设一条自冷凝器壳程出口至回流罐的不凝气放空管道；对脱丁烷塔分程控制系统进行了改造，即将调节器输出信号的0-45%，55%%-100%分别用于控制热旁路调节阀和放空阀。

Aiming at the characteristics of saving water, using the water safely and the limited field, the surface evaporative air cooler, perfect safety measures and integrated cooling and cooling water system are adopted in design; the degassing tank is set up in the discharging tube of the cooler for solving gas disposition of the system.

针对系统要求节水、安全用水、设备布置场地狭窄等特点，设计采用了表面蒸发式冷却器及集成冷却和冷却水系统，在空冷器出水总管设置脱气罐，解决了系统积气问题，并采用了完善的事故保安措施。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
