  • Patent number: 11957608
    Abstract: Aneurysms are treated by filling at least one double-walled filling structure with a curable medium within the aneurysm. The filling structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Scaffolds are placed into the tubular lumens in order to help maintain the shape, anchor the filling structures in place, and provide improved blood flow transition into and out of the tubular lumens.

  • Patent number: 10384198
    Abstract: A process for injecting an immiscible liquid stream comprising a co-catalyst for a hydrocarbon conversion into a larger liquid stream that is an ionic liquid catalyst for the hydrocarbon conversion, comprising: a. feeding the immiscible liquid stream towards one or more injection quills in an additive delivery system comprising a transfer drum; b. transferring the immiscible liquid stream from the additive delivery system to the one or more injection quills in a solvent flushing system, fluidly connected downstream from the additive delivery system, wherein the solvent flushing system injects a solvent into one or more additive addition lines in the solvent flushing system; and c. continuously injecting the immiscible liquid stream into the larger liquid stream in an additive injection and mixing system comprising the one or more injection quills.

  • Patent number: 10279339
    Abstract: An integrated system comprising: a. an additive delivery system comprising a transfer drum that feeds an immiscible liquid stream towards one or more injection quills; b. a solvent flushing system, comprising one or more additive addition lines that transfer the immiscible liquid stream from the additive delivery system; and c. an additive injection and mixing system comprising the one or more injection quills, wherein the immiscible liquid stream is injected into a larger liquid stream. Also, a process comprising: a. feeding the immiscible liquid stream to a transfer drum; b. transferring the immiscible liquid stream from the transfer drum to injection quills in a solvent flushing system, wherein the solvent flushing system injects a solvent into one or more additive addition lines in the solvent flushing system; and c. injecting the immiscible liquid stream into the larger liquid stream in an additive injection and mixing system comprising injection quills.

  • Publication number: 20140142204
    Abstract: A process and system are described for producing a synthetic crude oil by contacting a synthesis gas with a combination of a synthesis gas conversion catalyst and a hydroconversion catalyst in a synthesis gas reactor. The synthesis gas can be obtained from gas associated with crude oil production, i.e., associated gas, in a synthesis gas generator. The synthetic crude oil can be blended with a natural crude oil to produce a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil. The resulting blended stabilized crude oil has improved flow characteristics including a pour point of 30° C. or less.
