Patent number: 11505514Abstract: The present disclosure provides natural gas and petrochemical processing systems, including oxidative coupling of methane reactor systems that may integrate process inputs and outputs to cooperatively utilize different inputs and outputs in the production of higher hydrocarbons from natural gas and other hydrocarbon feedstocks. The present disclosure also provides apparatuses and methods for heat exchange, such as an apparatus that can perform boiling and steam super-heating in separate chambers in order to reach a target outlet temperature that is relatively constant as the apparatus becomes fouled. A system of the present disclosure may include an oxidative coupling of methane (OCM) subsystem that generates a product stream comprising compounds with two or more carbon atoms, and a dual compartment heat exchanger downstream of, and fluidically coupled to, the OCM subsystem.Type: GrantFiled: November 18, 2020Date of Patent: November 22, 2022Assignee: Lummus Technology LLCInventors: Guido Radaelli, Suchia Duggal, Joel Cizeron, Wayne Schammel, Franciscus J.

Patent number: 11186529Abstract: The present disclosure provides a method for generating higher hydrocarbon(s) from a stream comprising compounds with two or more carbon atoms (C2+), comprising introducing methane and an oxidant (e.g., O2) into an oxidative coupling of methane (OCM) reactor that has been retrofitted into a system comprising an ethylene-to-liquids (ETL) reactor. The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C2+ compounds. The first product stream can then be directed to a pressure swing adsorption (PSA) unit that recovers at least a portion of the C2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C2+ compounds. The second product stream can then be directed to the ETL reactor. The higher hydrocarbon(s) can then be generated from the at least the portion of the C2+ compounds in the ETL reactor.Type: GrantFiled: June 19, 2019Date of Patent: November 30, 2021Assignee: LUMMUS TECHNOLOGY LLCInventors: Suchia Duggal, Guido Radaelli, Jarod McCormick, Andrew Aronson, Joel Cizeron

Patent number: 11008265Abstract: In an aspect, the present disclosure provides a method for the oxidative coupling of methane to generate hydrocarbon compounds containing at least two carbon atoms (C2+ compounds). The method can include mixing a first gas stream comprising methane with a second gas stream comprising oxygen to form a third gas stream comprising methane and oxygen and performing an oxidative coupling of methane (OCM) reaction using the third gas stream to produce a product stream comprising one or more C2+ compounds.Type: GrantFiled: August 12, 2019Date of Patent: May 18, 2021Assignee: Lummus Technology LLCInventors: Humera A. Rafique, Srinivas Vuddagiri, Guido Radaelli, Jarod McCormick, Suchia Duggal, Joel Cizeron

The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C2+ compounds. The first product stream can then be directed to a separations unit that recovers at least a portion of the C2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C2+ compounds.Type: GrantFiled: March 18, 2019Date of Patent: May 11, 2021Assignee: Lummus Technology LLCInventors: Suchia Duggal, Guido Radaelli, Jarod McCormick, Andrew Aronson, Joel Cizeron, Divya Jonnavittula
