Acid Recovery

Naxidic Acid and Acid Recovery

Recovered Naxidic acid is more powerful and faster acting than a typical recovered acid.

Hydrochloric Systems

The virgin acid used in these systems is replaced with a hydrochloric based Naxidic Acid and introduced into the recovered acid stream. The same general results outlined for Naxidic Acid and hydrochloric acid pickling would be available. Continuous strip lines generally show considerable cost savings when tapping into the Naxidic Acid’s ability to pickle cooler. Slight reductions in temperatures of two to five degrees C (five to ten degrees F) can produce sizeable cash savings in energy costs.

Sulfuric Systems

Sulfuric acid recovery by cooling returns an acid containing enough iron which inhibits the pickling reaction. Including a sulfuric based Naxidic Acid as a part of your acid recovery process will off-set the inhibiting properties of the returning iron. Naxidic Acid releases all the latent energy in your pickle to remove scale quickly and efficiently. You can pickle colder, conserving energy in the pickle and the recovery unit because your 10% returning Naxidic acid acts as if it were a 12% acid.

Phoenix Systems Cold Process

Phoenix Systems Acid Recovery

Phoenix Systems Cold Process for sulfuric acid recovery and WIM Acid Additives are the perfect combination for today’s cost conscious high quality world of pickling steel.

Phoenix Systems Cold Process for sulfuric acid recovery and WIM Acid Additives are the perfect combination for today’s cost conscious high quality world of pickling steel. The Phoenix System Cold Process returns a recovered acid well below 2% In iron. This adds up to 3 days’ or more additional life before the next recovery. Adding a WIM Acid Additive to the pickle offsets the inhibiting properties of the iron in solution as it builds towards the next recovery cycle…The acid acts as if there were no iron in the bath…A cleaner scale free pickle…A better surface to form subsequent coatings for drawing / cold forming or hot dip galvanizing.
