Publication number: 20150101406Abstract: In various aspects, methods and systems are provided for monitoring catalyst bed levels using multiple sensors that are temporarily installed in a reactor during catalyst loading. The multiple sensors are able to take distance measurements at substantially the same time and at predetermined time intervals so as to provide a catalyst time profile. The catalyst time profile allows an operator monitor catalyst levels during and after catalyst loading. Once catalyst loading is completed, the multiple sensors are removed from the reactor.Type: ApplicationFiled: September 15, 2014Publication date: April 16, 2015Applicant: ExxonMobil Research and Engineering CompanyInventors: YI EN HUANG, David C.

Patent number: 6102843Abstract: A one-pass centrifuge separator for mixtures of two liquids which may also contain gas. The centrifuge uses separation zones on a rotor's inner wall to improve separation efficiency and minimize turbulent mixing. The zones consist of surface and interface vanes, and baffle plates to control flow at the fluid interface. The zones also retain an open concept to facilitate washing by cleaning fluids which are provided by nozzles installed on a stationary feedpipe mounted along the rotational axis of the centrifuge. A fluid accelerator gradually accelerates the fluid from the feedpipe to the inner wall of the rotor.Type: GrantFiled: March 19, 1996Date of Patent: August 15, 2000Assignee: ExxonMobil Upstream Research CompanyInventors: Lonny R.
