What’s the situation with the old purge tower in the dry gas tower?
Thread Content
The pressure at the top of the tower can be unstable depending on the amount of dry gas produced in the coking process; tank 3204 tends to fill up easily
How can dry gas be filled to capacity, unless the dry gas contains oil?
The dry gas desulfurization tower 3204 is entirely filled with rich liquid
What is the differential pressure in the main gas desulfurization tower of the building? Is the differential pressure too high?
The gauge for pressure difference is broken... It just won’t be fixed
In our dry gas desulfurization tower, once the differential pressure increases, the amine solution is carried over to the collector
Is the actual dry gas volume higher than the designed value? Additionally, a large pressure difference between inlet and outlet can also cause this situation.
Dry gas volume exceeds design capacity； The rich liquid may foam severely; enhance filtration or replace it ； The packing tower is clogged; it needs to be cut out and cleaned
Generally, it is due to solvent foaming (the dry gas produced by coking contains coke particles, which can easily cause solvent foaming), or an unstable flow rate of the dry gas, leading to tower flooding
