  • Patent number: 11193483
    Abstract: A high pressure gas lift compressor system and method of using the system for supplying compressed gas to multiple wells are provided. The system includes a compressor having multiple compressor cylinders. Each cylinder has its own gas inlet line and dedicated gas outlet line that supplies compressed gas from that cylinder directly to a wellbore to provide artificial gas lift. Each cylinder also has its own control valve upstream of the cylinder to control the suction pressure to the cylinder. A desired gas flow rate to each well may be input, and the control valve is adjusted accordingly to achieve the flow rate. By inputting a flow rate for each separate cylinder, the flow rate to each well may be independently controlled.

    Abstract: An air compression apparatus includes an air tank, an air compressor, and a governor. The air compressor delivers compressed air to the air tank by using power of an engine at the time of load running and stops the delivery of the compressed air to the air tank at the time of no-load running. The governor switches between the load running and the no-load running of the air compressor. Furthermore, the governor changes, when an engine speed is equal to or more than a threshold value, switchover timing for switching the air compressor from the no-load running to the load running in comparison with a time when the engine speed is less than the threshold value.

  • Patent number: 8450701
    Abstract: A cold trap filter and method is provided for filtering chemical species from a vacuum system of an ion implantation system. A canister is in fluid communication with an exhaust of a high vacuum pump and an intake of a roughing pump used for evacuating an ion source chamber. One or more paddles are positioned within the canister, wherein each paddle has a cooling line in fluid communication with a coolant source. The coolant source passes a coolant through the cooling line, thus cooling the one or more paddles to a predetermined temperature associated with a condensation or deposition point of the chemical species, therein condensing or depositing the chemical species on the paddles while not interfering with a vacuum capacity of the high vacuum and roughing pumps. The paddles can also be electrically biased to electrostatically attract the chemical species to the paddles in one or more biasing steps.

  • Publication number: 20130129531
    Abstract: A multistage compressor installation in which compression stages utilizing centrifugal compressors are independently driven by drivers that can be electric motors configured to be controlled by a speed controller. Intercoolers are located between stages to remove the heat of compression and the stages are connected such that outlets are located opposite to inlets of the compressors and conduits connecting the intercoolers to the stages are in an in-line relationship to inhibit the formation of pressure drops between stages. The conduits connecting the stages incorporate tapered transition sections configured such that flow velocity gradually decreases towards the intercooler and gradually increases from the intercooler to the next succeeding compression stage to further inhibit pressure drops.

  • Publication number: 20120291434
    Abstract: Method for recovering energy when compressing a gas using a compressor system with two or more compression stages, with each stage having a compressor element. Downstream from at least two compressor elements there is a heat exchanger having a primary and a secondary part. The coolant is guided successively in series through the secondary part of at least two heat exchangers, and the guiding sequence is chosen such that the temperature at the inlet of the primary part of at least one subsequent heat exchanger is higher than or equal to the temperature at the inlet of the primary part of a preceding heat exchanger, relative to the direction of flow of the coolant. At least one heat exchanger is provided with a tertiary part for a coolant.

  • Patent number: 8308439
    Abstract: A method of operating a multistage gas compressor system including providing a plurality of compressor stages connected in series, receiving a gas flow having contaminants within a gas passage, and supplying solvent to the gas passage at or upstream of a compressor in a compressor stage of the plurality of compressor stages to entrap or dissolve the contaminants in the gas flow. The method includes resisting disabling fouling of the compressor in the compressor stage from any contaminants entrapped or dissolved in the solvent, for example, by controlling a discharge temperature of the compressor, and/or using a type of compressor that is not susceptible to being disabled by fouling in at least the first stage. The discharge temperature can be controlled by providing the compressor with a pressure ratio selected to provide a desired discharge temperature.

  • Patent number: 8221094
    Abstract: A screw compressor comprising: a low pressure stage compressor body; a high pressure stage compressor body that further compresses a compressed air compressed by the low pressure stage compressor body; pinion gears for example, respectively, provided on, for example, a male rotor of the low pressure stage compressor body and, for example, a male rotor of the high pressure stage compressor body; a motor; a bull gear for example, provided on a rotating shaft of the motor; and an intermediate shaft supported rotatably and provided with a pinion gear, which meshes with the bull gear, and a bull gear, which meshes with the pinion gears. Thereby, it is possible to make the motor relatively low in rotating speed while inhibiting the gears from being increased in diameter, thus enabling achieving reduction in cost.
