Alfa Laval reports on a case study of a sulphuric acid plant in Northwest China that is looking to capture its low-grade heat for re-use and to significantly reduce the amount of fossil fuels used in production.
The recovery of waste heat from Aurubis’ copper smelting operation in Hamburg is already helping to reduce global carbon emissions and has the potential to provide heat for up to 20,000 homes through the district heating network in Hamburg’s HafenCity. The energy for the network comes from waste heat that Aurubis recovers from their sulphuric acid plant, using unique Alfa Laval plate heat exchanger technology.
