FRI’s parallel projects
Considering that Fractionation Research, Inc. (FRI) has been performing distillation research since 1954, don’t we have all the answers yet? Not according to the membership. The vendors of trays and packings have had very aggressive R&D programs. New and interesting products have appeared annually. In addition to the testing of such products in hydrocarbon service and at commercial diameters, the...

Crow’s nest
The fact that I was 150 ft up, on the outside of an extraction column, in January, in Canada, in a 20-mph wind, was not the worst part of the experience. The worst part was that the column was not working properly, and I had helped to design it. Like most industrial columns, this one had vertical ladders on its side. Each ladder led to a landing, or so-called deck. Each ladder was surrounded by a cage. The...

Earthquake fractionation
Some columns sway with the wind; some columns sway with the waves. In fact, hundreds of columns now reside offshore, on platforms and on barges. Most dry and sweeten gases. Some distill. The trays and packing distributors of such columns are regularly, appreciably out of level. Sloshing occurs. The packings are regularly, appreciably off vertical. Some of what we know about the design of such columns...

Reboiler Circuits For Trayed Columns
The reboiler generally supplies most of the energy required to effect component separation. If too much heat is supplied, the tower may flood; conversely, if too little heat is available, separation performance may decrease via poor reflux ratio (pinching), excessive weeping or poor tray action. Proper design of reboiling systems involves coordinating aspects both outside and inside the tower. This article...
