Heating of a copper-rich mineral by-product by means of using shell and tube heat exchangers
SACOME has supplied two shell and tube heat exchangers for the heating of a copper-rich mineral by-product contains a sulfuric acid concentration of around 2%.
In these tubular heat exchangers, the entire product side channel has been manufactured in 904L and the inner tubes have been manufactured according to UNS 08904 without longitudinal welding according to ASTM A269.
The process consists of heating the mineral by-product from 28ºC to 37ºC, by means of hot water that is recovered from other systems of the factory.
A strict quality control for both, materials and welds, have been carried out. These shell and tube heat exchangers are intended to be operational 24 hours/day.
