The device experienced a major power outage
Thread Content
When a major power outage occurs in the company, how should the air for backwashing and loosening in the two-reactor system of the catalytic unit, as well as the pressure in the steam system, be managed at the points where gas is used?
At this point, the pressure inside the two devices is also not high, so it won’t cause blockages at any loose connections.
It’s mainly because there’s no power – where would the wind come from? Is the air compressor unaffected? Do you have a separate ventilation system?
I mean, should the root valve be turned off to loosen it a bit?
There’s no need to close it. On one hand, there are too many loose points, so it’s impossible to close them all in a short time; on the other hand, each of these loose points is equipped with a one-way valve, which prevents backflow or blockages
The operating procedure requires it to be turned off; failing to do so may cause the catalyst to flow back and lead to pipeline blockage
If the main air supply is activated after a call, will it cause blockages if it isn’t turned off?
After handling it according to the accident emergency plan, it’s best to turn it off. Regardless of whether air or steam is used, liquid water may form at the loose points as the temperature drops; this causes the catalyst to stick together and block those loose points. Once production resumes, whether these loose points can function properly has a significant impact on the fluidization of the inclined tubes
