Selection of heat exchangers for glyphosate mother liquor, material

The glyphosate mother liquor is weakly alkaline after treatment; it mainly consists of sodium halides and phosphates, with some ammonium salts present as well. The temperature has dropped from 120°C to around 35°C; we are seeking advice on which type of heat exchanger to use. During experiments, it was found that crystallization can indeed occur; so which type of heat exchanger should be chosen?
Since the final solution is alkaline, 304 stainless steel can be used as the material for the heat exchanger at this process condition. In fact, for the heat exchanger in this process, it is not the material quality that should be considered; rather, the type of heat exchanger is what matters – crystal precipitation may occur at this stage.
No way, upstairs. The mother liquor contains a large amount of chloride ions, which can cause severe corrosion to stainless steel and carbon steel!
Everyone needs to consider everything comprehensively; it’s important to look at the cost-performance ratio
