(Urgent help/Catalytic refining) Issue with nozzle linear velocity
Thread Content
How is the linear velocity of the feed oil nozzle in a riser calculated? For example, if the feed rate of crude oil is 90 t/h and the amount of atomizing steam is 10 t/h, are there any other influencing factors?
For different types of nozzles, the nozzle pressure drop and linear velocity will vary; it is best to check the relevant information for the nozzle you are using.
Reply to 3# BJYTABC: Brother, the key point is that what I need now are calculated values, not design values!
If you only provide flow rate without other values, it’s impossible to do the calculations; parameters such as pressure, flow rate, pipe diameter, and also the nozzle pressure drop are needed! ! !
