The upcoming inclined tube is blocked
Thread Content
The catalytic unit’s raw material inclined tubes were blocked, probably due to the detachment of the reactor lining. The method used in the workshop involved increasing the main flow rate, closing the regeneration slide valve, and maintaining a regeneration pressure higher than the reaction pressure in order to carry out backwashing; this approach finally resolved the problem. What do you think of this method? Are there any better solutions?
Standard Hugan. Just looking to die. Close the valve to be used, and introduce a large amount of steam through the sampling port for the substance to be processed; the effect should be similar to that achieved using the dry method as you mentioned.
In production, it’s sometimes necessary to take risks; the key is to conduct proper risk assessments and prepare for potential accidents. If everything goes well, the credit goes to the leadership’s sound decisions, but if problems arise, the responsibility lies with those at the grassroots level. It’s tough!
Reply to 2# karamay: The sampling port is equipped with an orifice plate; even if a bypass line is used, the amount of steam required won’t be high, so it’s likely to have little effect
