Publication number: 20230121512Abstract: A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.Type: ApplicationFiled: December 15, 2022Publication date: April 20, 2023Applicant: KELLOGG BROWN & ROOT LLCInventors: Cassandra Schoessow, Douglas Piotter, Anand Subramanian

Patent number: 11530172Abstract: Methods and systems for steam cracking a mixed butane containing feed stream are disclosed. The feed stream includes n-butane and isobutane. The disclosed methods and systems entail splitting the feed into an enriched n-butane fraction and an enriched isobutane fraction. The enriched n-butane fraction is provided to the cracking furnaces, which yield the olefin products and also yield C4 species. The C4 species are partially hydrogenated and provided as a reactant feed to an alkylation reaction. The enriched isobutane fraction is also provided to the alkylation reaction, whereby high value alkylate product is produced. The disclosed methods and systems have increase olefins (especially ethylene) yield because the feed to the cracking process is enriched in n-butane. The economics are also improved because high value alkylate product is produced from a portion of the isobutane.Type: GrantFiled: November 18, 2020Date of Patent: December 20, 2022Assignee: KELLOGG BROWN & ROOT LLCInventors: Rian Reyneke, Hendrik Wolterus Klavers

Patent number: 11529585Abstract: Methods and systems for treating volatile organic compounds (VOCs) generated in a hydrocarbon treating process are disclosed. An effluent stream containing the VOCs, as well as carbon dioxide (CO2) is combined with hot exhaust gas from a turbine and provided to a waste heat recovery unit (WHRU). The WHRU is adapted to contain a catalyst bed containing oxidation catalyst capable of effecting the oxidation of the VOCs. The temperature of the catalyzing reaction can be tailored based on the position of the catalyst bed within the temperature gradient of the WHRU. The methods and systems described herein solve the problem of effecting the removal of VOCs from the effluent. Heating the CO2-containing effluent in the WHRU also lend buoyancy to the effluent, thereby facilitating its dispersal upon release.Type: GrantFiled: April 26, 2021Date of Patent: December 20, 2022Assignee: KELLOGG BROWN & ROOT LLCInventors: Paul William Kingston, Olatunde Yusuf

Patent number: 11505752Abstract: An advanced regulatory controller for a converter of a catalytic olefins unit is disclosed. A Fluid Catalytic Cracking (FCC) type converter (i.e., reactor-regenerator) is combined with an ethylene style cold-end for product recovery. The regulatory controller operates using an Advanced Regulatory Control (ARC) application using variables, such as a controlled variable, four disturbance variables, associated variable, and a manipulated variable. The ARC application manipulates fuel oil or tail gas flow to a regenerator in response to an expected future steady state value of a regenerator bed temperature resulting from changes in the values of a selected set of the variables.Type: GrantFiled: August 12, 2021Date of Patent: November 22, 2022Assignee: KELLOGG BROWN & ROOT LLCInventors: Jorge Javier Vazquez, Surajit Dasgupta, Michael Tallman, Priyesh Harilal Thakker
