The device operates on the principle that entering vapor and liquid are contacted such that all of the liquid is entrained upward with the vapor. The dispersion process takes place in the contacting stage, and integral with this stage is a vapor-liquid separator. Collected liquid is returned to the tray below via an alternating side downcomer.
The net result of this configuration is that vapor flows from bottom to top, as in a traditional countercurrent contacting device, but the liquid travels down in loops, being entrained up one tray and then falling to the tray below in the downcomer. The CoFlo Tray has been tested at the Separations Research Program (SRP), at the University of Texas, which indicates that the CoFlo Tray provides up to a 100% capacity increase over sieve trays without sacrificing efficiency.
