For new NGL Fractionators such as deethanizers, depropanizer, debutanizers and deisobutanizers, trays are most commonly used, such as MINIVALVE® trays or FLEXITRAY® valve trays. High-capacity trays, such as SUPERFRAC® trays, can be used to reduce the column diameter and height to reduce capital cost.
For revamps of NGL fractionators, the existing trays can be replaced with SUPERFRAC® trays to increase the capacity and efficiency of the column. ULTRA-FRAC® trays can be used to increase the capacity of the column even further to maximize the product output using the existing column shell.
