Publication number: 20200140766Abstract: Systems and methods are provided for detecting abnormal temperature conditions within a fixed bed reactor. In a fixed bed reactor, a hydrocarbon (or hydrocarbon-like) feedstock can be exposed to one or more types of catalyst particles at elevated temperatures and/or pressures. In addition to the one or more types of catalyst particles, a plurality of temperature-sensor structures can be included in a catalyst bed and/or a coating including one or more temperature-sensor structures can be provided on an interior wall or other interior surface in the reactor. The temperature-sensor structures can have a threshold temperature at which the temperature-sensor structure changes to allow introduction and/or release of a detectable substance.Type: ApplicationFiled: January 7, 2020Publication date: May 7, 2020Inventors: Dana W. Nouri, Hans G. Korsten, Benjamin S. Umansky

Patent number: 9416324Abstract: A gas-liquid catalyzed reaction is performed by introducing at least a portion of the reactive gas into the catalyst as a cross-flow or radial-flow stream. Introducing at least a portion of the reactive gas as a radial flow stream allows the reactive gas to travel through the catalyst bed along a shorter path length. This reduces the pressure drop for the radial flow portion of the gas. The reactive gas can be introduced into the catalyst bed at various heights relative to the height of the catalyst bed.Type: GrantFiled: June 25, 2013Date of Patent: August 16, 2016Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventor: Hans G. Korsten

Patent number: 9126168Abstract: A structure and method are provided for adding a catalyst bed platform to an existing reactor without welding to the structural portion of the reactor walls. The structure is constructed from components that can be passed through an existing opening in a reactor. The structure allows a catalyst bed in an existing reactor to be divided into catalyst beds with a reduced length to diameter ratio.Type: GrantFiled: December 14, 2011Date of Patent: September 8, 2015Assignee: ExxonMobil Research and Engineering CompanyInventors: Antonio O. Ramos, Benjamin S. Umansky, William J. Tracy, III, Ramesh X. Gandhi, Hans G. Korsten, Enrique Feliz

Patent number: 8691159Abstract: A modular catalyst bed support can be used to increase the number of catalyst beds available in a reactor. The modular catalyst bed support can include a lattice with a plurality of lattice openings and modules inserted into the lattice openings. The modular catalyst bed support can rest on top of an underlying catalyst bed, which can reduce or eliminate the need for attachment of the modular catalyst bed support to the walls of the reactor.Type: GrantFiled: March 15, 2012Date of Patent: April 8, 2014Assignee: Exxonmobil Research and Engineering CompanyInventors: Antonio O. Ramos, Benjamin S. Umansky, William J. Tracy, III, Ramesh X. Gandhi, Hans G. Korsten, John T. Wyatt, Jr., William J. Novak

Publication number: 20140037419Abstract: Methods, devices and processes for effectively loading catalysts into reactor vessels. In particular methods, devices and processes for effectively loading catalysts into fixed bed reactors utilizing inducted vibrational energy to improve catalyst loading performance, thereby resulting in improved flow distribution through the catalyst beds at designed operating conditions. The methods herein are particularly effectively for improving the performance of new or existing catalyst bed configurations of vertically-oriented two-phase hydroprocessing fixed bed reactors.Type: ApplicationFiled: August 2, 2013Publication date: February 6, 2014Applicant: ExxonMobil Research and Engineering CompanyInventors: Antonio O. Ramos, Chithranjan Nadarajah, Hans G. Korsten, Benjamin S. Umansky, Yi En Huang
