RETRAYING AND REVAMP DOUBLE BIG LPG FRACTIONATOR'S CAPACITY

Richard Sasson Independent Engineering Consultant Friendswood, Tex. Robin Pate Enterprise Products Co. Houston Retraying existing columns and making other process improvements allowed Enterprise Products Co., Houston, to raise capacity on its "West Texas" fractionator at Mont Belvieu from 35,000 b/d to 60,000 b/d for a lower cost than a new 25,000 b/d parallel train. The expanded distillation unit uses no more fuel to distill 60,000 b/d than the old unit did to distill 35,000 b/d.
