CPVC producer Lubrizol
Corrosive exhaust air is cooled below the water dew point resulting in a reduction of the energy consumption of the dryer of 8%.
8% energy savings
170 kW heat recovered
Payback time 2 years for equipment
Ambition to reduce energy
Lubrizol is committed to environmentally responsible and sustainable solutions. To reduce their energy consumption on the drying process of CPVC, they wanted to recover heat from the exhaust air of their dryer.
HeatMatrix polymer APH
Previously no heat was recovered from the exhaust air of the dryer, because of the high hydrochloric acid content in it. When cooled down, through the water and acid dew point, hydrochloric acid is formed and corrosion occurs. A HeatMatrix polymer APH was selected, because of its ability to handle corrosive exhaust air.
Energy savings of 170kW
Incoming cold air is heated from 10 to 56 °C, resulting in an energy saving of 170 kW. Corrosion free heat recovery is achieved.
