Abstract: A hydrogen-rich hydrocarbon fuel gas can be separated into a methane fuel stream and a hydrogen product stream. The methane fuel stream can be fed to a methane fuel fired furnace, combustion of the methane fuel stream can produce a carbon-dioxide-rich flue gas, and a carbon capture process can be performed on the carbon-dioxide-rich flue gas. The hydrogen product stream can be fed to a hydrogen fired furnace or elsewhere. Combustion of the hydrogen product stream in a hydrogen fired furnace can generate a flue gas the is low in carbon dioxide. Electrolysis of water obtained from the hydrogen fired furnace flue gas can produce hydrogen for a desired use, such as fuel for the hydrogen fired furnace, and can produce oxygen for enriching the fuel gas fed to the methane fuel fired furnace.

Abstract: Systems and methods for improved mixing, including baffle systems, reactor systems, and methods of using the same are provided herein. These baffle systems include a ring having an exterior surface defining an outer diameter and an outer circumference, an interior surface defining an inner diameter and an inner circumference, a top surface, a bottom surface, and an axis; and one or more substantially vertical baffles extending from the interior surface of the ring toward the axis.

Abstract: Methods for operating a high pressure olefin polymerization reactor include the steps of introducing an initiator stream containing ethylene and an initiator compound through an initiator nozzle into the reactor, introducing an olefin stream containing ethylene and an optional comonomer through an olefin nozzle into the reactor, and polymerizing ethylene and optionally the comonomer in the presence of the initiator stream in the reactor under high pressure polymerization conditions to produce an ethylene polymer. The amount of ethylene in the initiator stream is from 0.01 to 2 wt. % of the amount of ethylene in the olefin stream. An injection nozzle that can be used in conjunction with the high pressure reactor also is described.

Abstract: Methods of reducing heat exchanger fouling rate or of producing polyolefins may include providing a first gas stream comprising a gas and entrained fine polyolefin particles to a gas outlet line; removing a portion of the entrained fine polyolefin particles from the gas outlet line to form a bypass stream; and providing the bypass stream to a bypass line comprising a bypass line inlet and a bypass line outlet. The bypass line inlet and outlet are located upstream and downstream of a first heat exchanger. The methods may further include providing at least a portion of the first gas stream to the first heat exchanger; and combining the bypass stream and a second gas stream at the bypass line outlet to form a combined gas stream comprising one or more olefins or paraffins. A temperature of the combined gas stream is below the dew point of the combined gas stream.

Abstract: A remotely controlled oil drain valve assembly is provided. The assembly comprises a valve body which is threadably connected to the crankcase of an internal combustion engine. A valve core is slideably mounted within the valve body. Ports in the valve body and valve core, when in alignment, permit the flow of oil from the crankcase through a passageway in the valve core. The ports are brought in alignment by means mounted in the valve body which receive an electric signal from a remote source to cause rotation of the valve core to the proper position.

Abstract: A remotely controlled oil drain valve device to be installed in the threaded drain plug opening of automotive crankcase permitting drainage of crankcase oil without removal of the crankcase plug. A cylindrical tapered valve core having cylindrical arms extending from end surfaces of said cylindrical tapered valve core and being seated in a cylindrical tapered valve seat opening of a cylindrical valve body having an affixed threaded tubular nipple extending radially from said cylindrical valve body, and a disk-shaped cable bracket yoke having an extended arm affixed selectively to said cylindrical valve body by means of threaded fasteners.
