Publication number: 20120073435Abstract: 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.Type: ApplicationFiled: September 23, 2011Publication date: March 29, 2012Applicant: LINDE AKTIENGESELLSCHAFTInventor: Andreas SELIGER

Publication number: 20120024151Abstract: 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.Type: ApplicationFiled: April 6, 2010Publication date: February 2, 2012Inventor: Ian Gray

Patent number: 8080087Abstract: 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.Type: GrantFiled: October 24, 2008Date of Patent: December 20, 2011Assignee: ExxonMobil Research & Engineering CompanyInventors: Robert J. Falkiner, Bal K. Kaul

Patent number: 8075668Abstract: 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.Type: GrantFiled: March 29, 2006Date of Patent: December 13, 2011Assignee: Dresser-Rand CompanyInventors: Scott J. Delmotte, Jon T. Vine, Thomas D. O'Leary

Publication number: 20110290108Abstract: 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.Type: ApplicationFiled: May 25, 2010Publication date: December 1, 2011Applicant: Honeywell International Inc.Inventors: Sanjay Kumar Sharma, Ravi Nath

Publication number: 20110233144Abstract: 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.Type: ApplicationFiled: September 22, 2010Publication date: September 29, 2011Inventor: Derald L. McCabe

Publication number: 20110168017Abstract: Method and device for degassing a liquid of a substantially closed liquid circulation system at a working pressure. The method comprises passing at least a partial flow of the liquid through a restriction into a chamber in which a degassing pressure is maintained, the degassing pressure being higher than atmospheric pressure and lower than the working pressure, separating gas withdrawn from the partial flow of liquid from the partial flow, removing the gas from the chamber, and pumping the degassed partial flow of the liquid back into the substantially closed circulation system. The restriction comprises a nozzle, and the step of passing at least the partial flow of the liquid through the restriction into the chamber comprises spraying at least the partial flow of the liquid through the nozzle into the chamber for obtaining a jet and/or mist of the liquid in the chamber.Type: ApplicationFiled: July 24, 2008Publication date: July 14, 2011Applicant: SPIRO ENTERPRISES B.V.Inventor: A.
