High Sodium Sulfate Pilot Test with Various Materials
High Sodium Sulfate Pilot Test with Various Materials
(OP)
We are being asked to perform a 3 month pilot test to treat process water with 15% sodium sulfate, pH around 6, temperature around 95-110 deg F. The only equipment we have (to meet the deadline) has epoxy-coated, 1/4" plate, carbon-steel tanks, with 304L nozzles (flanged and threaded). There are several welded fittings and structural members in the tank that are coated with marine epoxy. I can change out the valves and piping to PVC. The epoxy coating has decent coverage, but I have seen rusting in normal marine environments after a year in service.
We expect the equipment to get ruined in the process, but will it last the 3 months? What kind of damage should I expect?

What about impurities? If the pH goes down and/or you get any chlorides in the system then making 3 months could be a stretch.
