Hydrochloric and Mixed Acid Recovery

You are here

Both our Hydrochloric and Mixed Acid Recovery Systems use vacuum evaporation to remove iron from the inactive, spent acid. Vacuum evaporation has proven more efficient than atmospheric evaporation because its lower operating temperature (80 dC vs 120dC) extends the life of the components and uses less natural gas. The capital cost is lower as well because the heat exchangers can be smaller and the smaller tanks/vessels can be made inhouse at Beta rather than from a third-party tank manufacturer.

 

Hydrochloric Acid Recovery

Typically, our customers have spent acid that isn't "dead" entering the HCl Recovery System:  6% HCl, 8% Fe, and 0 - 2% Zn. Our systems separate the HCl and water vapor from the metals to yield a return acid stream of approximately 16 - 18% HCl.

Mixed Acid Recovery

FINALLY, a solution to the mixed acid recovery problem! Based on our HCl Recovery System's design, with just a few changes in materials and components, these systems can recover dangerous streams of HF/HCl and HF/HNO3 safely and efficiently.  Plus, often the metal contamination, such as titanium, in these mixed acids is quite valuable, so their recovery results in a high dollar savings.
