Publication number: 20190112537Abstract: A Flexicoking™ unit which retains the capability of converting heavy oil feeds to lower boiling liquid hydrocarbon products while making a fuel gas from rejected coke to provide only a minimal coke yield. The heater section of the conventional three section unit (reactor, heater, gasifier) is eliminated and all or a portion of the cold coke from the reactor is passed directly to the gasifier which is modified by the installation of separators to remove coke particles from the product gas which is taken out of the gasifier for ultization. In one embodiment, a portion of cold coke is transferred directly from the reactor to the gasifier, and another portion of cold coke is combined with hot, partly gasified coke particles transferred directly from the gasifier to the reactor. The hot coke from the gasifier is passed directly to the coking zone of the reactor to supply heat to support the endothermic cracking reactions and supply seed nuclei for the formation of coke in the reactor.Type: ApplicationFiled: December 21, 2018Publication date: April 18, 2019Inventors: Suriyanarayanan Rajagopalan, Glen E. Phillips, Mohsen N. Harandi

Publication number: 20170233667Abstract: A method for utilizing the heating value of clarified shiny oil (CSO) by in which clarified slurry oil from the settler of a fluid catalytic cracking unit is introduced as feed to the gasifier of a Flexicoking unit where it is reacted at high temperature with the air and steam to produce additional heat. In this way, the heating value of the CSO is better utilized as refinery fuel gas and plant economics are enhanced.Type: ApplicationFiled: February 17, 2016Publication date: August 17, 2017Inventors: Mohsen N.

Patent number: 8658025Abstract: Biomass is used as a co-feed for a heavy petroleum oil coking process to improve the operation of the coking process and to utilize biomaterial for the production of transportation fuels. The coking process may be a delayed coking process or a fluidized bed coking process and in each case, the presence of the biomass will decrease the coke drying time so reducing coke handling problems in the unit besides forming a superior coke product. In the case of a fluidized bed coking process using a gasifier for the coke, the addition of an alkali metal salt improves the operation of the gasifier.Type: GrantFiled: March 1, 2011Date of Patent: February 25, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Michael Siskin, Glen E. Phillips, Simon R. Kelemen, Walter Weissman
