Fast Track Reformer Retrofit

............................................................................
............................................................................

Ed Samuels will provide a 5 minute opening introductory statement covering the overall scope of Cominco's turnaround done in 1989. He will indicate the overall budget of the project and that the Kellogg reformer portion of the revamp was the heart of the project. Cominco's motivation in such a major

0 overhaul of the reformer was because of it,laging condition, t o get an updated design with improved energy efficiency, and a reduction of effluents with the addition of a saturator convection coil design. He will introduce me as one of the Kellogg representatives who worked closely with Cominco throughout the course of the project from conception t o its completion i n the field.

Cominco Fertilizers Amonia/Urea f a c i l i t y located in Borger, Texas just north o f Amarillo, has a Kellogg reformer designed and constructed in the early 1960's. The reformer radiant section has had one catalyst tube changeout since the original installation, and the convection superheat coil was changed

0 It was Cominco's requirement that all of the reformer and associated plant modifications be implemented during October 198% and be completed within 29 days from plant shutdown to plant start-up. In order to accomplish this feat in what turned out to be an extremely tight materials market, non-traditional approaches were utilized for both engineering and construction. In this paper, the means used for successful project completion are discussed.

convection and radiant section of the furnace. All catalyst tubes were changed out in the radiant section, a new effluent chamber installed, complete new insulation in the radiant firebox, all new catalyst tube and effluent chamber springs installed, new crossover piping and crossover support system, and new design inlet manifolds with new pigtails installed. The existing convection section was completely demolished and replaced with a new and significantly larger convection section which was completely shop fabricated and shipped to the jobsite in modular form to save construction erection costs. The new convection design incorporated a steam saturator coil ded.gi+ and convection section superheat burners. In support of the new convection design, improvements were made in the desulfurization system, along with all...
