N2  - Resumen del autor, extraído del trabajo. The Eluxyl™ paraxylene separation process, using simulated countercurrent adsorption, has been co-developed by IFP and Chevron. Following the successful operation of the Chevron Pascagoula Demo Plant, several large or very large capacity Eluxyl units have been awarded. These awards are based on the ability of this innovative, leading-edge technology to offer customers lower capital investment and operating costs and to enable the purification of world scale paraxylene throughputs in a single separation train. This article discusses the process features of the Eluxyl Hybrid and the opportunities for retrofitting crystallization units by integrating this modern technology. A special focus on the Chevron’s Pascagoula refinery experience, from the demonstration plant which has proved out the Eluxyl technology to the succesful revamp of the initial two-stage crystallizer into an Eluxyl Hybrid unit, will be given. This unit has started-up in 1998 and is the first example of the cost-effective combination of IFP’s versatile, innovative adsorption section and Chevron’s modern, high-temperature crystallization process. The Eluxyl Hybrid Technology solution affords a paraxylene purity of 99.8 % for conventional users and up to 99.9 % for the most demanding users
