Discussion on the oil temperature issue of the butterfly valve at the inlet of the flue gas exhaust system in catalytic units
Thread Content
What is the oil temperature at the butterfly valve at the inlet of the flue gas extractor in the catalytic unit? Does a temperature exceeding 60 degrees have a significant impact on the operation of this valve?
What water do you use for cooling? Is it recycled water?
The target temperature here is 65 degrees; in actual use, it reaches a maximum of 63 degrees, which does not affect the operation of the equipment! Desalinated water is used for cooling water.
What is your alarm temperature? Here, it triggers an alarm at 60 degrees
An alarm at 65 degrees usually resolves itself with the on-site cooler flushing; if that doesn’t work, switch to direct exhaust!
It has been in operation for 8 years without any scaling.
It’s better to replace it; after 8 years of use, it can be acid-washed online
