Direct Contact Process Dryer Heat Recovery
Based on energy investigations involving process dryers at manufacturing, oilseed crushing and oil extraction facilities over the past four years, Kinergetics has designed systems to recover heat from the dusty exhaust that often results during normal drying process operations. The Kinergetics design incorporates an “open column” direct contact design that will not plug or foul as contact columns with mass transfer packing often do. The contact column was designed specifically for more challenging process heat transfer applications and is called the ExTactor™, for Exhaust conTactor. Aside from more reliable long term operation, the ExTactor also has a lower pressure drop for increased energy efficiency, which also lessens concerns about loss of drying capacity due to increased system back-pressure.
