-What kind of pump is suitable for 100-degree frozen saline?
-Freezing saline at 100°C? I don’t know what component it is. For this type of transfer pump, it is necessary to address the issues of corrosion resistance and the cold brittleness of steel; it is recommended to use stainless steel IS pumps, along with the addition of corrosion inhibitors to the system.
1. For low flow rates, a reciprocating cryogenic liquid pump is selected; flow rate: 20–1500 L/h； Maximum operating pressure: 40MPa ； 2. Flow rate: 3000-45000L/h ； A three-plunger pump can be used: a high-flow reciprocating medium-pressure low-temperature liquid pump, horizontal type, single (double, triple) row configuration, with electromagnetic/variable-frequency speed control, and long cycle time ； Maximum operating pressure: 5.5 MPa ； 3. Flow rate: 1.8–60 M3/h ； Centrifugal cryogenic liquid pumps can be used ； Head: 50-75M 4. High flow rate: o Centrifugal pumps can be used, 20-500M3/h ； Head: 55-140M. The figures above are just suggestions; the actual value should be determined based on your process parameters, the current location, and your company’s maintenance capabilities
Low-temperature brine is generally an ethanol glycol + deionized water solution; the lower the temperature of the brine, the higher the concentration of ethanol glycol, which is used primarily to lower the freezing point and prevent the deionized water from freezing:lol
