Copper producer Rio Tinto replaces hot gas exchanger

Prominent copper producer Rio Tinto Kennecott (RTK) recently replaced its sulfuric acid plant’s hot gas exchanger for a new design capable of withstanding the very high gas temperatures from the company’s smelter in Magna, UT. Variable gas strength originating from the smelter had been exposing the company’s old exchanger to gas temperatures above its design threshold causing tube failures.
