Heating of a copper-rich mineral by-product by means of using shell and tube heat exchangers
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.
Heat exchangers technical documentation
The importance of rheology in the design of any processing plant is crucial since the sizing of many of the elements composing it is very dependent on this “resistance”, also taking special relevance with food products: heat exchangers, pipes, valves, pumps, mixers, etc.
To design a heat exchanger it is necessary to have certain data, such as the process flow rate, the temperature and the physical properties of products.
Hairpin heat exchangers have a more efficient and economical design compared to a multiple pass heat exchanger when the process requires a temperature crossing between the cold and hot fluid.
