Different materials need different types of heat exchanger. For the simplest fluids such as water and milk, plate heat exchangers are often sufficient, but as products become more challenging (for example more viscous, or containing particles), then different types of tubular and scraped surface heat exchangers are required. For those products with extremely high fouling…

At UK AD & World Biogas Expo 2018 stand D603, HRS Heat Exchangers will showcase its novel Digestate Concentration System (DCS), which increases the dry solid content of digestate three-or four-fold, typically to between 10-20 per cent. By reducing the liquid fraction and therefore the overall volume of digestate produced, the DCS minimizes the economic…
