Definitions

  • TITLE Gas Compressor with Drier and Radio Emission Controls
  • This invention relates to the compression of gases. More particularly, it relates to the compression of natural gas and/or hydrogen for use in vehicles propelled by such gases. Specifically, it relates to an apparatus and methods for removing moisture vapor as part of the compression procedure and separating removed moisture from contaminants therein. It also relates to minimizing the release of electromagnetic radiation.
  • de-watering processes generate extracted water that may contain traces of contaminants originating from the principal stream.
  • these contaminants include hydrogen sulphide, sulphur dioxide and mercaptans .
  • Disposal of water containing contaminants of this type can be subject to environmental restraints.
  • a compressor for a gas which normally operates on a gas compression ' cycle is provided with a gas drier stage comprising a single desiccant bed located in-line with the flow of gas passing through the compressor during the gas compression cycle. Also located in-line with such gas flow is a condenser which, during the compression cycle, is inactive.
  • the temperatures of the desiccant bed and condenser are both controllable, preferably by electrical means. During the compression cycle, such temperature controls are preferably inactive. However, upon entering into a regeneration cycle, the gas bed is heated and the condenser is cooled.
  • gas trapped within the compressor, desiccant bed and condenser is redirected from the outlet of the compressor for circulation in a closed loop as a recirculating gas flow through the compressor, with at least a portion of such recirculating gas passing through the dessicant bed and condenser.
  • the outlet from the compressor is connected through an electronically controlled valve to the delivery line which carries compressed gas off to a storage reservoir during the compression cycle.
  • the electronically controlled delivery valve switches the flow of gas .from the delivery line into the interior • volume of a casing cavity for the compressor. The compressor draws its input from the casing cavity.
  • the resulting drop of pressure in the delivery line causes a check valve at the external reservoir, which contains high pressure gas, to close.
  • the compressed gas trapped in the delivery line then "blows down" into the interior volume of the casing, producing a pressure condition that is moderately elevated above that of the supply line pressure eg 30-60 psi.
  • the check valve at the supply line inlet to the interior volume then closes as the source gas pressure is only of the order of 0.2 to 0.5 psi.
  • Circulation of the gas within this closed loop is effected at a low gas flow rate so that the circulating gas passing through the condenser is substantially, preferably fully, chilled when it exits the condenser. This maximizes the efficiency of transferring moisture from the desiccant bed to the condenser as a preferred mode of operation. Circulation may be effected at a low flow rate by reducing the speed of the compressor motor. Alternately, one or more valve-controlled bypass lines may divert a portion of the circulating gas around the dessicant bed, and/or the condenser, allowing only a limited amount of gas flow through these components.
  • the permitted flow rate over the bed is set so as to be commensurate with the condensation of vapor from such gas.
  • This arrangement allows the system to operate with a fixed speed motor.
  • water evolves from the desiccant bed, raising the moisture content of the circulating gas.
  • the desiccant bed is heated at . this stage to enhance its release of moisture.
  • the released water, in vapor form is then carried by the gas flow to the condenser where it condenses due to the low temperature condition maintained within the condenser. Circulating gas exiting the condenser leaves the condenser in a cooled, vapor saturated, condition.
  • the circulating gas By the time the circulating gas reaches the heated desiccant bed, its temperature has been raised and the gas is no longer vapor saturated.
  • the heated circulating gas is therefore able to absorb further moisture from the desiccant bed as it passes over such bed.
  • water may simply be collected.
  • the condensed water is directed, preferably flowing under gravity, into contact with a semi-permeable membrane which allows the water to evaporate.
  • aromatic compounds present within the condensate are retained by the membrane within the condenser.
  • an external fan and optional heater element may be preferably positioned to circulate warm air past the membrane surface.
  • the condenser is located in-line with the gas flow during the compression cycle. This exposes the condenser and semipermeable membrane to an elevated pressure condition.
  • the compressor is a multi-stage compressor and the desiccant bed and condenser are positioned in-line between consecutive stages, preferably between the first and second stages of the compressor.
  • condensed water accumulating in the condenser is directly, or eventually, disposed of by release into the environment, preferably through the semi-permeable membrane.
  • Use of such a membrane ensures separation and retention of complex
  • the compressor is contained within a sealed metal casing.
  • Supply gas enters the interior volume of this casing through a check valve and is drawn into the compressor from the crank-portion of this interior volume.
  • the motor preferably a variable speed motor, and preferably control circuitry for delivering current to the motor.
  • the motor is an alternating current induction motor, and in the variable speed situation the control circuitry produces an alternating current signal of varying frequency, whereby the speed of the motor is varied in accordance with system requirements .
  • the control circuitry may deliver current at 360 volts DC provided through a sealed penetration of the casing wall.
  • the motor control circuitry operates to create alternating current having a frequency of on the order 60 Hz but with multiple harmonics.
  • the electrical power delivered to the motor provides current, at a typical maximum level, of on the order of 8 to 10 amps.
  • the electromagnetic radiation from the wiring extending between the control circuitry of the motor carrying a such current at such frequencies is a source of electromagnetic radiation. By confining this wiring to within the metallic casing, electromagnetic radiation from this source is shielded from entering into the environment.
  • low motor speeds are preferably adopted to reduce otherwise high start-up current drains on the electrical supply system.
  • This enables the unit to operate off of a standard household voltage, e.g. 110-120 volt, moderately fused electrical supply system.
  • initial compression can be effected with a high motor speed.
  • the motor speed is reduced in order to moderate ring wear and limit power consumption.
  • This procedure is especially suited to oil-less compressors as the wear rate of the sealing rings within the compressor cylinders of such units increases when the compressor system is operated at high speed against a high-back pressure.
  • the speed of the electric motor may also be controlled to avoid natural resonant frequencies arising from its mechanical components that would otherwise increase the noise and vibration generated by the unit.

Abstract

Cette invention concerne une unité compresseur de gaz comprenant un seul lit de dessiccation du gaz et un condenseur (qui est inactif pendant la phase de compression) introduit dans le circuit d'écoulement du gaz du cycle de compression. Dans le cas d'un compresseur à plusieurs étages, le lit de dessiccation du gaz unique est placé de préférence entre le premier et le deuxième étage. L'humidité absorbée par le lit est périodiquement évacuée au moyen d'un procédé consistant à exposer le lit à un cycle de régénération. Le cycle de régénération utilisé repose sur la recirculation fermée du gaz présent dans le compresseur et le lit de dessiccation lui-même, ainsi que d'un autre gaz présent dans la boucle de recirculation lorsque le compresseur interrompt la distribution de gaz comprimé. L'humidité évacuée du lit de dessiccation est condensée et de préférence s'évapore dans le milieu ambiant par une membrane semi-perméable. Le moteur et l'unité de commande du moteur sont placés avec le compresseur dans un logement commun afin que les émissions électromagnétiques soient réduites au minimum.
