Patent number: 8695813Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.Type: GrantFiled: December 8, 2007Date of Patent: April 15, 2014Assignee: Spectra Analysis Instruments, IncorporatedInventors: William W.

Publication number: 20140091049Abstract: Certain examples relate to a new feedwell design for use in a clarifier that may better dissipate the entrance energy of the slurry-liquid combination exiting the feedwell and entering the clarifier. Plates of various shapes may be provided proximate to the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials; while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. This may, in turn, permit solids to better “settle out” of the slurry-liquid combination, and thus improve the clarity of the removed liquid.Type: ApplicationFiled: September 13, 2013Publication date: April 3, 2014Applicant: Andritz Inc.Inventor: Lindsay BRANDINO

Publication number: 20140008278Abstract: The oil-water separator is installed in a substantially horizontal crude oil pipeline for separating water from the oil and water mix. The separator includes a vortex and settling chamber extending downward from the pipeline. The segment of the pipeline having the separator defines a generally T-shaped configuration. Oil and water phases flowing through the pipeline drop into the chamber as it flows through the pipeline and over the chamber. The denser water tends to settle into the bottom of the chamber, while the lighter oil is entrained back into the flow through the pipeline. A sensor detects water collected in the bottom of the chamber and provides a signal to open a drain valve when sufficient water has been collected. While only a single separator serves to collect a substantial fraction of water, a series of separators may be installed along the pipe to remove more water from the oil.Type: ApplicationFiled: July 9, 2012Publication date: January 9, 2014Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: HASSAN MOHAMED BADR, WAEL HASAN AHMED

Patent number: 8622225Abstract: An assembly for water purification comprising a series of vessels which allows fluid to communicate therebetween via fluid supply lines. The assembly is arranged so as to generate a plurality of co operating vortices generated by fluid impact on formations disposed on an inner surface of the vessels to cause an ascending fluid flow to be deflected back in the direction of fluid flow thereby creating local vortices. Water exiting said vessels has higher purity than water entering the vessel.Type: GrantFiled: May 2, 2007Date of Patent: January 7, 2014Inventor: Brien Edward Goninan

Publication number: 20140001117Abstract: A system includes a hydrocyclone liner. The hydrocyclone liner includes a head section having a fluid inlet and an overflow outlet. The hydrocyclone liner also includes a separation section having an underflow outlet and a first sidewall. A diameter of the separation section of an outer surface of the first sidewall is constant along a length of the outer surface of the first sidewall. The head section and the separation section are joined together via a bond at an interface between the head section and the separation section. The hydrocyclone liner includes a sleeve disposed about at least a portion of the head section, the separation section, and the interface. The sleeve is configured to hold the head section and the separation section together if the bond fails.Type: ApplicationFiled: June 28, 2012Publication date: January 2, 2014Applicant: CAMERON INTERNATIONAL CORPORATIONInventors: Nigel Hugh Abraham, Michael John Kingsley

Patent number: 8617405Abstract: A method of separating a multiphase fluid, the fluid including a relatively high density component and a relatively low density component, that includes introducing the fluid into a separation region; imparting a rotational movement into the multiphase fluid; forming an outer annular region of rotating fluid of predetermined thickness within the separation region; and forming and maintaining a core of fluid in an inner region. Fluid entering the separation vessel is directed into the outer annular region and the thickness of the outer annular region is such that the high density component is concentrated and substantially contained within this region, the low density component being concentrated in the rotating core. A separation system employing the method is also provided. The method and system are particularly suitable for the separation of solid debris from the fluids produced by a subterranean oil or gas well at wellhead flow pressure.Type: GrantFiled: June 15, 2007Date of Patent: December 31, 2013Assignee: Cameron International CorporationInventor: Hans Paul Hopper

Publication number: 20130327726Abstract: A method and apparatus are disclosed for separating a multiphase fluid stream that includes a heavier fluid component and a lighter fluid component. The fluid flows along a first helical flowpath with a first pitch. The first helical flowpath is sufficiently long to establish a stabilised rotating fluid flow pattern for the stream. The uniform rotating fluid also flows along a second helical flowpath, the second helical flowpath having a second pitch greater than the first pitch. The lighter fluid is removed from a radially inner region of the second helical flowpath. The method and apparatus are particularly suitable for the separation of oil droplets from water, especially from water for reinjection into a subterranean formation as part of an oil and gas production operation. The method and apparatus are conveniently applied on a modular basis.Type: ApplicationFiled: August 12, 2013Publication date: December 12, 2013Applicant: Cameron International CorporationInventor: Hans Paul Hopper

Publication number: 20130319952Abstract: A method of controlling a hydrocyclone system for separating a fluid mixture wherein the system includes a separator vessel for receiving the fluid mixture and performing a primary separation of the more dense and the less dense fluid phase thereby forming an interface within the separator, and a hydrocyclone apparatus having a first and second hydrocyclone compartments to separate the phases. The method includes alternating the flow rate through the hydrocyclone apparatus, alternating the interface or fluid mixture level in the separator vessel between a first level and a second level; and alternating the second hydrocyclone compartment between an open state in flow communication with the first hydrocyclone compartment and a closed state in isolation from the first compartment.Type: ApplicationFiled: June 1, 2012Publication date: December 5, 2013Applicant: NATIONAL OILWELL VARCO, L.P.Inventor: Mark E.
