The feed water for the company’s acidic water stripping unit includes acidic water from hydrocracking, acidic water from hydroreformation, water from atmospheric and vacuum distillation, and water from vacuum distillation. May I ask if the saline wastewater from atmospheric and vacuum electrical desalination can be fed into acidic water stripping? What will be the outcome if I go in?
The waste brine from electrodialysis cannot be discharged into acidic water, as this wastewater consists mainly of non-volatile electrolyte salts such as chlorides, sodium salts, and calcium salts, which can cause corrosion, scaling, and blockages. Introducing this water into the stripped acidic water is pure recklessness.
The salt-containing wastewater from electrodialysis is sent directly to the wastewater treatment plant
The company’s management plans to use steam stripping to remove sulfur from the desalination wastewater, on the grounds that its sulfur content is too high; personally, I think this approach won’t work.
Yes, because the purified water is meant to be reused in the upstream devices, enabling recycling
There is no hydrogen sulfide in there; what’s the point of introducing acidic water? It also wastes stripping steam.
Electrodialysis is a method for desalination – how can there be sulfur?
The deionized water produced by electrodialysis cannot be introduced into acidic water, as the wastewater from electrodialysis consists mainly of non-volatile electrolyte salts such as chlorides, sodium salts, and calcium salts, which can cause corrosion, scaling, and blockages. If an ammonia extraction device is used along the pipeline, it will block the lines; it’s best not to try it as the costs outweigh the benefits. Generally, this water should be sent directly to the sewage treatment plant
