Environmental Benefits:

This recycle eliminates deep well disposal of the stream. Since installation of the project, the HCN concentration has not reached the 5% limit. It appears the HCN is flashing into the vapor space of the tank and being vented to the flare where it is burned. The pickling solution has only been sent back to the HCN refining train when the acid concentration of the solution dropped below the desired concentration.
