How to prevent corrosion from the high-pressure separation tank to the liquid separation tank?

2007-12-31View Original

Thread Content

The liquid discharged from the circulating hydrogen separation tank of my hydrogenation unit is basically acidic water brought from high temperature. The temperature of high temperature is 40°C. The dangers of pipeline corrosion over a long period of time can be solved by experts. Please give me some advice on how to prevent corrosion without stopping the machine or replacing the pipeline. :lol It seems a bit difficult

In normal production, the moisture content in circulating hydrogen should be very small, especially since the high temperature you control is so low, I think there are several reasons why there is so much water (for reference only): 1. The foam breaking net at the top of the high score is damaged or the foam breaking net is improperly installed or the mesh density is inappropriate. 2. The amount of hydrogen circulating in the device is too large, exceeding the maximum line speed allowed by the high-end top foam breaking net. 3. The vortex separator inside Gaofen (it seems to be called this) is improperly designed, or the device is overloaded. The above reasons will increase the amount of water carried, and will also increase the amount of light hydrocarbons carried. If your device is only severely water-charged, it is recommended to change the water injection of your device to intermittent injection, which can reduce the water content in the circulating hydrogen, thereby reducing the corrosion of the rear pipelines.

The liquid separated from the hydrogen separator tank in a normal cycle should be close to the low-separation component. If all the liquid coming out of the bottom of the separator tank is acidic water, you should check whether there is any problem with the internal components of your high-end liquid separator.

Dude! I want to tell you that there is a huge difference between low liquid content and low liquid content, just like the difference between gasoline and residual oil.

It shouldn't be possible to solve the problem without replacing the pipeline, but how severe is the corrosion you mentioned? It should be able to support it for two years, right?

If it is impossible to park the car, make a jacketed pipe on the structure and set up a second line of defense.

The analysis on the third floor has been quite comprehensive and thorough. The high-end temperature does not exceed 50 degrees, which should be caused by excessive processing volume. Of course, it is also possible that there is a problem with the high-end internal parts. However, it seems impossible to perform anti-corrosion without stopping the machine. It is recommended that the owner reduce water injection as much as possible and control the processing volume without causing blockage of the air-cooling pipe bundle. If there is still a lot of fluid, it is recommended to submit an overhaul plan now, and when the vehicle is shut down for overhaul, a comprehensive inspection of the internal parts with a high score will be performed and dealt with thoroughly.

Since it is unavoidable, I think we should increase the amount of water injection and the frequency of drainage to reduce the concentration of acidic water to reduce corrosion.
