Abstract: A method and system for capturing hydrogen gas in a refinery is disclosed. The system comprises a first membrane and pre-reformer. The membrane is suitable for separating a refinery fuel gas feed, which includes hydrogen gas and hydrocarbon gases, into a hydrogen gas depleted retentate stream and a hydrogen gas enriched permeate stream. The pre-reformer receives the retentate stream from the first membrane and catalytically converts the retentate stream into an outlet stream of hydrogen and methane gases. The system may further include a reformer which receives at least a portion of the outlet stream and catalytically converts the methane gas into hydrogen and carbon oxides. A second membrane may be used for separating the outlet stream into a second hydrogen depleted retentate stream and second hydrogen enriched permeate stream. The reformer, in this case, receives the second hydrogen depleted retentate stream to provide methane for steam reforming.

Abstract: An H-28 machine has a plurality of identical sections each processing a gob of molten glass into a parison and then into a piece of ware each complete revolution of the section. Each section includes a blank mold displaceable between a parison forming position and a retracted position by blank mold down air.Each section also includes a plunger which is displaceable from an elevated position down to the parison forming position and a neck ring assembly which includes an air motor. Finally the section also includes a blow mold displaceable from a remote position to a closed position. The air motor is operated from the time that the blank mold begins its displacement from the parison forming position to the retracted position by a valve which connects blank mold down air to the air motor.

Abstract: An H-28 machine for forming glass containers comprising a cylindrical timing drum having inner and outer surfaces and a timing cam having a circumferentially extending inner surface for matingly engaging the outer drum surface. A pair of elongated circumferentially extending slots are cut in the timing drum. A slider matingly engages the inner surface of the drum and is held against the outer surface of the timing drum by first and second spring biased studs supported by the slider. A motor driven horizontally extending linear actuator which extends between the timing drum and the slider horizontally displaces the slider to horizontally circumferentially displace the timing cam.

Abstract: Controlling gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest.
