Waste Hydrochloric Acid


2002

Hi,

I am working in fastener manufacturing company in Dubai. In phosphate coating process we use hydrochloric acid (31%) for pickling. When the strength of this acid goes low, its pickling becomes insufficient & we have to throw this acid (assay about 12%). For this acid again we need Effluent costs to neutralize etc. Could anybody tell me the recycling process for this to recover acid or any companies who can buy this acid from us.

Regards,

There are acid additives that can extend the life of the acid. There are also acid recovery systems, but they are usually more suited to steel mill size pickling operations rather than phosphatizing shops. As for selling the acid, I would be amazed if a buyer could be found.
