Scaling problem in frozen salt water pipelines
Thread Content
Our company’s freezing workshop has recently noticed that the blockages in the refrigerant brine delivery pipelines are becoming increasingly severe. This directly affects the cooling effect of the cryogenic tank in the workshop. The main component of frozen saline is calcium chloride. The scale is estimated to be calcium sulfate. I would like to ask my friends: are there any methods to dissolve calcium sulfate in the pipelines, or to loosen it? It’s like adding acid to dissolve water heater scale. Is there still any good way?
Based on what you’ve said, it’s more likely that the particles in the saline have accumulated in the dead corners of the pipes or in the insulation layer of the freezer, which reduces flow rate and thus lowers the freezing efficiency. Although calcium chloride has better heat transfer properties and lower corrosivity than sodium chloride, industrial calcium chloride contains many mechanical impurities, so it should be filtered before use. If it is confirmed to be calcium sulfate, PP pipes can be used to transport saline!
Oh. Changing the pipes – the amount of work involved is truly enormous. What we need to do now is find a way to dissolve the calcium sulfate in those pipes, so as to loosen it. I just checked some information; it seems that calcium sulfate doesn’t dissolve in acids nor in bases. If organic solvents (such as EDTA) are used for cleaning, the temperature needs to be above 80 degrees Celsius, and the process takes a long time as well. The cost is too high. Are there any other methods?
Hello, owner. Our company specializes in the research, development, and production of calcium sulfate scale removers. If you have time, let’s talk about it. Thank you!
Is it necessarily calcium sulfate? Could it be salt crystals in the chilled water? Try blowing it with steam; also, give the pipelines a high-pressure cleaning
Then purchase calcium chloride of good quality with fewer impurities; this will **reduce the formation of impurity deposits**. Those who need calcium chloride can contact me at 18067279835. I mainly supply anhydrous and dihydrate calcium chloride produced by Juhua
Was the problem solved? It uses a calcium sulfate cleaning agent with a pH value of 7.0±0.1; it is non-corrosive and acts rapidly and effectively, removing calcium sulfate at a rate visible to the naked eye. If you’re interested, I can send you samples for free to try them out – I guarantee they work well. Of course, you need to make sure that the scale sample is indeed calcium sulfate.
