Purification of catalytic dry gas
Thread Content
After the catalytic dry gas is desulfurized, it contains a small amount of amine liquid. How can this amine liquid be removed? Thank you!
Typical dry gas users install a liquid separation tank after the equipment.
To solve this problem from an operational perspective, methods such as installing coagulators and liquid separation tanks are available; the key is to achieve control and resolution through proper operation.
For the polyamine liquid separator, care must also be taken during operation to ensure that the dry gas temperature is lower than that of the amine liquid, in order to prevent liquid from being carried along
It is still necessary to properly control the amine liquid level in the dry gas desulfurization tower in order to reduce the total amount of amine liquid carried away with the dry gas. Additionally, liquid separation tanks should be installed at each user site; generally, high-wattage liquid separation tanks are used in front of the heating furnaces. These are the measures that can be taken. Next, it is necessary to ensure that the level gauge of the dry gas desulfurization tower is accurate; if it is not accurate, there is a risk of significant liquid entrainment.
I have a amine liquid recycler installed, but lately there has been no increase in the liquid level inside it. I’m not sure if this is due to the stable operation mentioned by someone upstairs
Gas-liquid centrifugal separators, gas-liquid buffer tanks, and coagulators are all viable options; entrainment should be avoided as much as possible during operation.
Maintain stable pressure in the dry gas pipeline network; the circulation rate and temperature of ethanolamine should not be too high
