    Abstract: A method and an equipment for improving global warming and air pollution are proposed, wherein hot exhaust gas generated by a thermal machine is injected into an exhaust boosting unit to be compressed and mixed with a liquid medium for atomization. Pollutants in the hot exhaust gas and heat generated due to combustion are adsorbed by the liquid medium. After the liquid medium passes a dust collecting unit, the pollutants adsorbed by the liquid medium will adhere to the dust collecting unit. Humid and hot clean air is extracted to the atmosphere, and rises to high altitudes and is cooled there. Water will drop to the ground in the form or rain or snow to cool the ground temperature and remove other pollutants in the air. Heat circulation and water circulation can be sped up to improve the situation of global warming and render more water resource to the Earth.

    Abstract: A gas liquid separator system for a hydrogen generating apparatus includes a collection area for collecting liquid from the generated gases. To empty the collection area occasionally so that liquid does not build up and become entrained again in the dried gas, a vent solenoid is provided in communication with the collection area and a pump is used to create a vacuum periodically on the electrolysis cells. Such arrangement is used to open the liquid gas filter and possibly just the sump to atmosphere occasionally and vacuum generated to draw the liquid from the sump back to the electrolysis cells.

  • Publication number: 20120079937
    Abstract: A device for capturing gas included within a produced-water stream is described. Gas and water pressure coordination is not required. Controls prevent liquid entry to the gas system and prevent gas entry into the water system. A gas/liquid separator receives an inner vessel lower end. A separator inlet receives a combined fluid stream. A liquid line passes into the inner vessel and down into the separator below the inlet so that liquid separated from the combined stream will flow up the liquid line. Motor valves are in the liquid line and in a gas line. The gas line extends from the inner vessel upper end. The gas line conveys gas from the inner vessel upper end to a gas collection system. A top float in the inner vessel activates the gas line motor valve. A bottom float in the inner vessel activates the liquid line motor valve.

  • Publication number: 20120073435
    Abstract: The invention relates to a gas scrubbing process, as well as a method for the operation thereof, in which during normal operation in an absorber column, gas components are separated from a gas mixture (feed gas) by scrubbing with a scrubbing liquid. The scrubbing liquid, loaded with separate gas components during the scrubbing process, is regenerated in a regeneration system that comprises at least one regeneration device equipped with a liquid level control. The regenerated scrubbing liquid is then recycled into the absorber column. When the feed gas is lost/reduced, the nominal value of the liquid level control is raised, and the resultant additional storage volume provided in the regeneration device is used for storing scrubbing liquid.

  • Publication number: 20120024151
    Abstract: The invention is a separator designed to separate an incoming stream of liquid, gas, and some particulate matter into a separate gas stream, and a separate liquid stream containing the particulate matter. This is achieved through cyclonic action and the use of a float to operate internal valves within the cyclone. The float is mounted on a shaft which is rotated by the motion of the incoming fluid stream and this motion is used to agitate the solids in the liquid so as to prevent the outlet port from becoming jammed. The outlet port also has an auger contained therein that removes particulate matter.

  • Patent number: 8080087
    Abstract: A method of drying liquid and gaseous hydrocarbons by contacting a feed stream of the hydrocarbon with an aqueous solution of a salt drying agent prior to passing the stream through a salt dryer to remove part of the water in the stream. The aqueous solution of the salt drying agent is generated in the salt dryer when the partly dried stream comes into contact with the drying salt and forms the solution. The solution is circulated in a loop from the salt dryer to the incoming feed and then through a liquid/liquid coalescer which removes a portion of the water together with dissolved salt from the mixture before the mixture is passed on to the salt dryer where further removal of water occurs. The salt dryer is off-loaded by a substantial factor by the initial partial dehydration and does not require to remove such a large amount of water; the salt consumption is therefore reduced in proportion to the amount of water removed in the treatment steps which precede the dryer.

  • Patent number: 8075668
    Abstract: A drainage system is for a compressor assembly that includes at least one separator with a chamber. The system includes a drain valve fluidly coupled with the separator chamber and adjustable between open and closed states. An actuator is operatively coupled with and adjusts the valve between the open and closed states or/and a sensor senses when the valve is open. A pressure sensor is configured to sense pressure within the chamber and a logic circuit is coupled with the pressure sensor and determines when the valve either has been or should have been adjusted to the open state. The logic circuit also generates an output signal or/and operates a device when the chamber pressure remains substantially constant or varies by less than a predetermined amount subsequent to the valve being opened and/or when the chamber pressure varies by at least the predetermined amount after the valve is opened.

  • Publication number: 20110290108
    Abstract: A system includes a controller and an apparatus that includes a housing having a volume and an inlet. The inlet can receive a fluid that includes a gas and a liquid. The apparatus also includes a baffle that partitions the volume into a first portion and a second portion. The baffle extends from a base of the housing. The first portion can receive the liquid and separate the liquid into a first part and a second part. The second portion can receive the second part of the liquid from the first portion. The controller regulates an amount of the second part of the liquid in the second portion such that a level of the second part of the liquid is higher than a height that the baffle extends from the base of the housing, thus enabling the use of the extra surge capacity in the vessel.

  • Publication number: 20110233144
    Abstract: The present invention is directed to a method and apparatus for improved separation or clarification of solids from a solids-laden liquid. Entrained gasses can also be removed. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid to be treated is directed through a conduit within the separator. Preferably the conduit within the separator is configured into a tortuous flow path to assist in the separation of solids from the liquid. Vibrational energy is applied to the flow path, preferably through the flow path conduit. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes and gas sparging can also be employed.
