Steam problem to prevent coking in catalytic settlers
Thread Content
Should the anti-coking steam for the settler be low-pressure or medium-pressure steam? Do they each have their own advantages and disadvantages? (Our unit has converted the anti-scaling steam from medium-pressure superheated steam to low-pressure steam); what about you? I hope to receive guidance from all the teachers. Thank you!
Of course, medium-pressure steam is the best!
Now our low-pressure steam temperature can also reach 280°C; so what is the reason for choosing medium pressure?
What is the reason for choosing medium voltage?
Why has your unit changed the anti-scaling steam from medium-pressure superheated steam to low-pressure steam? The reason for choosing medium-pressure steam is that it has good quality, which makes it more effective at preventing the formation of coke. Of course, devices that do not use medium-pressure steam can also use low-pressure steam.
It depends on the design provided by the design institute; the steam pressure is related to the size and orientation of the openings in the coils. Additionally, medium-pressure steam has good quality
Well, our unit used medium-pressure superheated steam as anti-coking steam in the past, but now it has been changed to low-pressure steam! What other advantages does medium-pressure steam have besides temperature?
Your 280-degree low-pressure steam is superheated; the normal value should be 240, right?
Low-pressure superheated steam is sufficient; medium-pressure steam is not needed. Since medium-pressure steam has a high pressure and fast flow rate, it can easily damage the anti-coking steam orifice plates or the equipment, and it is not easy to form an anti-coking steam cushion.
