Abrasion of the coaxial catalytic catalyst bed riser and sleeve
Thread Content
How to deal with the wear through of the coaxial catalytic raw catalyst riser and sleeve, as well as the poor sealing of the plug valve? Structure diagram
Shut down for maintenance; if there’s a leak in the sleeve, it will only get worse. For safety reasons, it’s best to shut down and carry out repairs
Shut down for maintenance; if the wear on the vertical pipe is minor, the temperature in the dilute phase will remain high. If the wear becomes severe, the plug valve will no longer function
If the grinding becomes excessive, it’s not just the dilute phase that is affected; most likely, the stripping efficiency cannot be properly controlled, which leads to an increase in bed temperature. An unstable pressure control in the settler can result in mixing of oil and gas, which is dangerous
