PLUS Technology for SUPERFRAC® Tray

The patented PLUS technology acts as a deentrainment device and can decrease the efficiency loss that often occurs in low-liquid and high-vapor-rate applications. In these types of conditions, it is common for high vapor rates to blow the liquid off the trays. While the PLUS technology will not prevent a tray from blowing dry, it does help offset the efficiency losses that occur because of high entrainment in low-liquid-rate services. Gains of 5% in usable (efficient) capacity are typical.   

PLUS technology is installed below each tray and helps reduce the entrainment of liquid droplets from one tray to the next. The deentrainment device is a customized design that typically uses a specifically designed FLEXIPAC® structured packing. Because structured packing is used, this technology typically is not applied in fouling services. ​
