Description:

P2 Application:

1

Environmental Benefits:

The project is one of several which allowed the plant to discontinue the use of earthen settling basins to remove vanadium and other constituents from process wastewater before discharge through the Plant's permitted outfall. This project lowered the quantity of vanadium discharged to the Neches River by approximately 50% (based on only one year's operating data and not considering the quantity of product made in the first full year versus the base year). Filter cake produced in the recovery facilities is recycled to our catalyst vendor rather than disposing of it by landfilling. They recover vanadium from this filter cake and it is reused to manufacture steel.
The initial twelve months of operation recovered and recycled 3,600,000 pounds of filter cake from which 162,000 pounds of vanadium was recovered.
