Question regarding water replenishment in the top reflux tank of the amine solution regeneration tower
Thread Content
We have now created an opening on the reflux tank to add purified water. There is also a pipe for adding deionized water in the pipeline between the cooler at the top of the amine regeneration tower and the reflux tank. I would like to ask how to determine the amount of water for these two purposes When should desalinated water be used for replenishment? Thank you! @ylb913
We haven’t seen water supplementation at this location; we had thought of using it for salt washing and replacement. The amount of amine in the amine circulation system generally decreases over time, so it is necessary to add water regularly or occasionally. In theory, water can be added at any point in the circulation system, but we mainly add water to the amine circulation tank. It is also possible that the amount of system amine increases; in this case, a pipeline can be installed at the outlet of the acid water reflux pump to divert it to wastewater stripping. This pipeline can also be used for salt washing: water is added while the liquid is discharged externally, which essentially involves replacing the acidic water.
It is best to use deoxygenated water for replenishment; do not use purified water, as it contains high levels of salts and this can degrade the quality of the amine solution
Purified water should also have had the salt removed, right?
“What is purified water? I only know about the purified water obtained through sewage stripping, as well as the purified water at the outlet of wastewater treatment plants. The water purified by stripping contains sulfur, ammonia, etc., while the water purified at wastewater treatment plants has even higher salt content.
He must have replied to the wrong post; he probably wanted to reply to the post about what water should be used with MDEA. .
