Catalytic stabilizer tower
Thread Content
There is a deoxygenated water line at the inlet of the catalytic stabilizer reflux pump – what is its purpose?
Is it used to fill with water to replace liquefied gas during shutdowns?
There’s fresh water available; using deoxygenated water would be a waste, right?
It should be the liquefied gas line at the water level; fresh water is dirty, while deoxygenated water is clean.
It should be the liquefied gas and gasoline pushed up by water during shutdown.
During shutdowns, it is used for liquefied gas on the water surface; for safety reasons, deoxygenated water is used, while our company uses fresh water. This is because a shutdown of the plant could lead to a shortage of deoxidized water, and moreover, deoxidized water is expensive.
May I ask if your deoxygenated water line is located before the shut-off valve at the outlet of the reflux tank?
In our company’s system, it is located before the shut-off valve; if water pressure is applied, could the temperature of the deoxygenated water become too high?
Companies like ours use fresh water, so I don’t think there’s much difference
