Coking unit contact cooling reflux tank with coke powder
Thread Content
What are good methods for dealing with coke powder in the contact cooling reflux tank of coking units?
Does the coking cooling water containing coke dust also contain oil?
It’s normal for oil and gas streams to contain coke powder; they carry it when going to the distillation tower, and they will certainly also carry it if it is sent to vent. It’s only possible to reduce the amount carried; it’s impossible to eliminate it entirely
Actually, there’s no good solution; the characteristic of coking units is that coke dust is everywhere, and it can only be reduced, not eliminated. The reflux tank contains coke powder, so the steam supply rate must be controlled appropriately.
