Catalytic cracking re-refining slurry
Thread Content
After my unit started operating this year, there was a slight vibrating sound coming from the re-refining slurry nozzle; the situation improved after adjusting the atomizing steam. Dear sea friends, what percentage of the re-refining slurry volume does the atomization steam used in your systems typically account for? What is the pressure of the reprocessed oil slurry before spraying? The pressure in my unit is 0.5 MPa; is this the reason for the low slurry pressure? Thank you
The pressure before the nozzle in our device is 0.7 MPa; it is a CS nozzle, and the amount of vapor atomized by the nozzle is at the designed level. Since adjusting the amount of atomized steam has led to improvement, why not try adjusting the slurry pressure as well?
The vibration isn’t a serious issue; it can be eliminated by adjusting the oil and air circuits!
There’s no problem. The pressure required varies depending on the design of the nozzle manufactured by the supplier; the manufacturers have conducted tests and know what pressure yields the best atomization effect
What is the temperature of the reprocessed oil?
6# Adafi KH-4 nozzle slurry temperature around 300 degrees
