Pipeline blockage issues in the ammonia vaporization system
Thread Content
Ammonia vaporization systems generally incorporate liquid alkali. Some manufacturers add the liquid alkali in the feed pipeline before the ammonia vaporization tower, after the heat exchanger; others add it in the feed pipeline before the heat exchanger. Some manufacturers use a static mixer after adding the liquid alkali, while others employ an activated carbon filter after adding it, and so on. However, blockages occur when the alkali is mixed with the remaining ammonia solution, and the scale gradually decreases starting from the moment the alkali is added. At present, we resolve this by disassembling and cleaning the equipment. What methods are others using to deal with this issue? Is there any way to handle it online without shutting down production?
We also carry out regular manual cleaning!
The dirt removed is dissolved using steam and hot water; only a small portion dissolves. Has a analysis of the components that make up the dirt been done?
