Can a heat exchanger with crystals use multiple passages?

Can a heat exchanger with crystals use multiple passages? Whether it is evaporation crystallization or freeze crystallization? Personally, I think it’s possible. The prerequisite is that the circulation pump must have sufficient head to ensure no loss in flow rate. At flow rates of over 1 m/s, most particles several hundred micrometers in size can be suspended. Of course, multiple units connected in series is also possible, but the cost might be slightly higher. Additionally, the shell side can be arranged in counter-current series flow, resulting in a temperature difference correction factor that is closer to 1. However, I really didn’t find such a case. I wonder what the experts here have to say? Could we exchange some practical experience?
