摘要： A planetary drive system that aligns four fluid ends for a pump or four compressor cylinders in the same plane, allowing for four fluid ends/compressor cylinders to be driven by one rotation of the pump's motor. Additionally, the planetary drive system is stackable to allow, for example eight, twelve, or other multiples of fluid ends or compressor cylinders to be driven while minimizing any reduction in output pressure. The chemical injection pump also includes threaded vents on the fluid ends to capture chemicals primed through the valves to avoid spillage and waste during the priming process. The air compressor cylinders also include pistons with enhanced vacuum actuation under a flexible inlet (e.g. flapper inlet).

摘要： A method of reducing drag in a conduit. The method includes producing ultra high molecular weight (UHMW) C4-C30 α-olefin drag reducing agent (DRA) and introducing the UHMW C4-C30 α-olefin polymer DRA into the conduit to reduce drag in the conduit. The catalyst consists essentially of at least one tertiary monophenyl amine selected from the group consisting of N,N-diethylaniline, N-ethyl-N-methylparatolylamine, N,N-dipropylaniline, N,N-diethylmesitylamine, and combinations thereof; at least one titanium halide having a formula TiXm, where m is from 2.5 to 4.0 and X is a halogen containing moiety; and at least one cocatalyst having a formula AlRnY3-n where R is a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-20. Further, the catalyst is absent of a carrier or support.

摘要： An apparatus and method for mixing a hydrogen sulfide scavenger with crude oil within a pipeline are disclosed. The hydrogen sulfide scavenger and the crude oil can be passed through a plurality of baffles disposed at spaced apart locations within the pipeline. The baffles can be used as an in-flow static mixer to produce increased circulation and flow speed which results in improved mixing of the hydrogen sulfide scavenger and crude oil.

摘要： A method of producing ultra high molecular weight (UHMW) C4-C30 α-olefin drag reducing agent (DRA). The method includes polymerizing in a reactor a first α-olefin monomer in the presence of catalyst and hydrocarbon solvent to produce the DRA. The catalyst consists essentially of at least one tertiary monophenyl amine having a formula R1R2N-aryl, where R1 and R2 are the same or different, and each is a hydrogen, an alkyl, or a cycloalkyl group, where at least one of R1 and R2 contain at least one carbon atom; at least one titanium halide having a formula TiXm, where m is from 2.5 to 4.0 and X is a halogen containing moiety; and at least one cocatalyst having a formula AlRnY3-n where R is a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-20. Further, the catalyst is absent of a carrier or support.

摘要： Embodiments of the invention provide a process in which a gas comprising biomethane having a heating value of less than about 925 BTU/cubic foot is introduced to a pipeline system that is connected to at least one source of natural gas having a heating value of at least about 950 BTU/cubic foot. The gas comprising biomethane combines with natural gas in the pipeline system to produce a mixed gas having a heating value below about 925 BTU/cubic foot. An amount of natural gas at least equal to the amount of gas comprising biomethane is withdrawn from the pipeline system for use as a transportation fuel, a fuel intermediate or as a feedstock for producing a fuel. The process can enable fuel credit generation and/or reductions in life cycle greenhouse gas emissions.

摘要： In various embodiments, an electronic flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. When the system is in a manual mode, backup manual flow selectors may be used to directly control the flow rate of a fluid. When the system is in a manual mode, the mechanical backup flow selectors may be in a deployed position. When the system is in an electronic mode, the mechanical backup flow selectors may be in a retracted position. Particular applications to gases and anesthesia delivery are disclosed herein.

摘要： The amount or extent of expositions as a result of hot smelt from a pulp mill recovery boiler impacting cool liquid in a dissolving tank is reduced more effectively by regulating the smelt flow via a restrictor assembly. The restrictor assembly may be positioned to permit the smelt to flow, unrestricted, from the recovery boiler to the dissolving tank, or the restrictor assembly may be positioned so as to fully or partially block the smelt flow from the boiler to the dissolving tank. In some embodiments, a source of cooling fluid may be coupled to the restrictor assembly so as to assist in cooling parts of the restrictor assembly when hot smelt is in contact with the assembly.

摘要： Methods of, and apparatus for, storing and transporting a hazardous fluid, such as a combustible fuel, include methods and means, respectively, for: (a) treating the fluid to reduce its hazardous condition; (b) storing and/or transporting the treated fluid in such a manner that the risk of its hazardous condition remains reduced; (c) thereafter retreating the fluid to restore it to its original hazardous condition so that the fluid may be used in its restored condition. The hazardous fluid may be treated by adding a substance to, or removing a substance from, the fluid, or by changing the state of the fluid. For example, if the fluid is a fuel, it may be treated by cooling it to near or below its freezing temperature to reduce its combustibility, volatility, explosivity and/or ease of ignition.

摘要： A timing apparatus is comprised of a magnet attached to the second hand of a clock and a reed switch. As the magnet passes by the reed switch, the reed switch closes and completes the circuit. The timing apparatus is used to control a pilotless ignition system that ignites waste gases in flare stacks from electrical discharges. The timing apparatus is also used to control a pipeline injection system.
