Publication number: 20240108846Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.Type: ApplicationFiled: December 5, 2023Publication date: April 4, 2024Inventors: Jason Allan Klenner, Andrew Paul Maxwell Salmon, Mark Samuel Hamilton, James William Stanton, Michael John Andresen, Jonathan Andrew George Lambert

Patent number: 11873263Abstract: The present invention concerns a process for oligomerizing an olefin feedstock to form an oligomerization product, and a method of controlling such an oligomerization process. The process comprises oligomerizing propylene to form a Cn olefin, including contacting a feed stream comprising propylene and a recycle fraction with a solid phosphoric acid oligomerization catalyst under effective oligomerization conditions in an oligomerization reactor to produce an oligomerization effluent; and fractionating the oligomerization effluent to obtain a product fraction and the recycle fraction, the product fraction comprising the Cn olefin and the recycle fraction comprising a Cn-3 olefin; wherein the recycle fraction comprises at least 80 wt % of the Cn-3 olefin, based on the weight of the recycle fraction; and wherein n is 9, or 12.Type: GrantFiled: March 10, 2020Date of Patent: January 16, 2024Assignee: ExxonMobil Chemical Patents Inc.Inventors: Andrew Wiersum, Paul Hamilton, Luc Martens, Sara Garcia Frutos, Marcel Janssen

Patent number: 11572325Abstract: Many linear alpha olefin (LAO) syntheses form a range of LAO products when oligomerizing ethylene in the presence of a Ziegler-type catalyst. The range of products typically requires a plurality of distillation columns to separate the LAO products up to a desired carbon count, but such approaches may be energy- and capital-intensive. LAO product separation using at least one dividing wall column may lessen these burdens. Methods for separating LAOs may comprise: providing a pre-processed product stream comprising Cg+ linear alpha olefins (LAOs) to a first of a series of distillation columns, at least one member of the series of distillation columns comprising a dividing wall column; and separating an overhead stream comprising a first LAO from the dividing wall column and one or more side streams from the dividing wall column, each side stream comprising a different LAO that also differs from the first LAO.Type: GrantFiled: November 14, 2019Date of Patent: February 7, 2023Assignee: ExxonMobil Chemical Patents Inc.Inventors: Robert Piszczek, Brian W. Heins, Paul Hamilton, Terrance C. Osby, Dion Zhang, Zhongcheng Wang, Michael L. Hergenrother, Jason A. Nichols

Patent number: 11512031Abstract: Linear alpha olefins (LAOS) may be formed by oligomerization of ethylene in the presence of a Ziegler-type catalyst. The presence of trace water during oligomerization can result in unwanted formation of insoluble higher oligomers or polymer. Methods for limiting the presence of water during ethylene oligomerization reactions may include separating residual ethylene and 1-butene from an LAO product stream to form a higher LAO-enriched stream comprising C6+ LAOs, separating 1-hexene as an overhead stream from the higher-LAO enriched stream using a first distillation column, obtaining separated solvent as a side stream from the first distillation column or as a side stream from a first of one or more downstream distillation columns, and returning the separated solvent to a reactor in a recycled solvent stream. The recycled solvent stream passes through one or more driers before returning to the reactor.Type: GrantFiled: November 14, 2019Date of Patent: November 29, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: Paul Hamilton, Terrance C.
