A technology for chemical removal of deposits with a high content of copper (over 18 %) from heat exchange equipment has been developed and tested commercially. The technology proposes a two-stage chemical purification. At the first stage, copper is removed from deposits, and at the second stage the deposits are dissolved with conventional techniques.

APPLICATION
Heat-and-power engineering, chemical industry, non-ferrous metallurgy.

ADVANTAGES
• Corrosive wear of heat exchange equipment is reduced.
• The technology is simple in use and utilizes cheap and available reagents.
