Cleaning Anhydrous HF line for Decommissioning

Q. We currently have a anhydrous HF line we will be decommissioning. We will use a lot of filtered river water to thoroughly flush Monel line. When we are finished, I would like to use the Alconox product to use as a final cleaner and neutralizing agent in the pipe before it is dismantled. I would like instructions on how much Alconox to use to perform the operation.

A. Fill the line with 1% Alconox. Flush the line with a minimum of three line volumes of water. Sample the final rinse to ensure that no persistent detergent foam is observed when the sample is agitated. If any characteristic detergent foam is observed, do an additional rinse.
