Patent number: 6783685Abstract: The invention is directed to an oil treatment apparatus and method for treatment of oil which transports oil to be treated from a source through a first conduit to a treatment station. The treatment station includes a filter system capable of extracting particulate material from the oil and removing the particulate material from the filter system as it is removed from the oil. The treated oil may then be transported for reuse, preferably in a continuous cycle with the source of the oil. A prefiltering system may be used to further enhance maintaining the quality of the oil and/or in efficiently treating the oil while accommodating throughput requirements. The prefiltering system may include a comminuter to reduce the size of larger particles in the oil, a coarse filtering system to remove larger particle, a system to introduce a treatment material to the oil or other systems to facilitate processing.Type: GrantFiled: April 24, 2001Date of Patent: August 31, 2004Assignee: FMC Technologies, Inc.Inventor: Yong Y.

Patent number: 6749655Abstract: A two-stage filtration system is coupled with an oven, such as a solder reflow oven, to remove a vapor stream from the oven and to remove organic compounds that have volatilized from a solder flux and other contaminants from the vapor stream. The filtration system includes a first stage for trapping larger particles and a second stage including a packed bed of wettable media, such as steel balls, for trapping smaller particles and serving as a nucleation site for condensed organic compounds. The first stage can be a centrifugal self-cleaning element in the form of a mesh strainer coupled with a rotary motor for spinning the mesh strainer.Type: GrantFiled: April 17, 2002Date of Patent: June 15, 2004Assignee: Speedline Technologies, Inc.Inventor: Jon M. Dautenhahn

Publication number: 20040069713Abstract: A process for treating a composition comprising one or more undesired compounds and one or more desired compounds so as to reduce the concentration of the one or more undesired compounds is described. The process comprises the steps of (1) contacting the composition with a solid adsorbent, (2) eluting the solid adsorbent on which the composition is retained with an extraction solvent comprising a (hydro)fluorocarbon, and (3) collecting a solvent eluate containing a composition having a reduced concentration of the undesired compounds from the solid adsorbent. The process is particularly suited to reducing the terpene content of an essential oil.Type: ApplicationFiled: October 24, 2003Publication date: April 15, 2004Inventors: Paul Alan Dowdle, Stuart Corr
