Publication number: 20190284482Abstract: Processes and systems for in situ heating of a heavy pitch within a coking drum are disclosed. The in situ heating may provide for processing of neat pitch, improving coking operations and increasing liquid yield.Type: ApplicationFiled: March 13, 2019Publication date: September 19, 2019Applicant: LUMMUS TECHNOLOGY LLCInventors: Ahmad A. Faegh, Daniel Bruce Gillis

Patent number: 10000705Abstract: A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.Type: GrantFiled: June 19, 2015Date of Patent: June 19, 2018Assignee: Catalytic Distillation TechnologiesInventors: Ahmad Faegh, John E. Collins, Virendra Manral, Gary Reisen

Patent number: 9452955Abstract: A process for upgrading residuum hydrocarbon feedstocks that may include: contacting a residuum hydrocarbon and hydrogen with a hydroconversion catalyst in a residuum hydroconversion reactor system; recovering an effluent from the residuum hydroconversion reactor system; separating the effluent to recover two or more hydrocarbon fractions including at least a vacuum residuum fraction and a heavy vacuum gas oil fraction; combining at least a portion of the heavy vacuum gas oil fraction and at least a portion of the vacuum residuum fraction to form a mixed heavy hydrocarbon fraction; feeding at least a portion of the mixed heavy hydrocarbon fraction to a coker; operating the coker at conditions to produce anode grade green coke and distillate hydrocarbons; recovering the distillate hydrocarbons from the coker; fractionating the distillate hydrocarbons to recover hydrocarbon fractions including a light distillates fraction, a heavy coker gas oil fraction, and a coker recycle fraction.Type: GrantFiled: February 19, 2014Date of Patent: September 27, 2016Assignee: Lummus Technology Inc.Inventors: Gary Sieli, Ahmad Faegh, Ujjal K. Mukherjee, Mario C. Baldassari, Marvin I. Greene
