This summer, Beta built and installed the largest system in North America. The system is essentially two systems with a common walkway. The processing capacity is 32,000 gallons/day of spent acid.
For this installation, operating temperatures will range between 40°F and 50°F, resulting in a residual iron concentration between 2.5% and 3.8% in the returning recovered sulfuric acid. The iron concentration in the recovered acid will remain in this range, irrespective of the iron input to the system. These results assume an incoming sulfuric acid concentration of at least 12% wt.
The pre-filter is the first stage of the process. Inexpensive spiral wound cartridges filter large particulate from the incoming spent acid.
Next, the spent acid enters the Reactor Tanks where it is agitated and chilled. The mixers increase the effectiveness of the immersion heat exchangers and create a crystal/acid slurry.

The Crystal Settler Tank is a conical fiberglass tank where the ferrous sulfate heptahydrate crystals in the slurry begin to settle at the bottom. The crystal-free recovered acid at the top of the tank overflows to a small Pump Back tank which returns the acid to the pickle line.
Finally, the settled crystals are spun dry by the Centrifuge and are transferred to one-ton super sacks. A specially made chute channels the crystals into the opening of the sack. We work with the space available inside the plant to determine the most efficient method of changing super sacks.
These functions are all controlled by Beta's software program. Customers may choose between a PanelView display mounted on the electrical panel, as shown on the left, and/or a computer near the system or in an office.
New Feature: Remote monitoring and troubleshooting by a Beta technician via wifi or cellular connection. Encrypted and secure.
