  • Publication number: 20120302478
    Abstract: This invention provides a method for producing a lubricant composition that is comprised of a continuous phase and a discontinuous phase. The method involves mixing together high viscosity ester, ether or combination thereof, and polar diluent or solvent, to produce a solution. The solution is then added to a low viscosity Group IV base oil to produce a discontinuous phase dispersed throughout a continuous phase.

  • Publication number: 20110031103
    Abstract: The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

  • Publication number: 20080242564
    Abstract: A method is disclosed for improving the cooling of equipment lubricated by functional fluids, such as power train fluids, by lubricating the equipment with a functional fluid comprising a wax isomerate or hydrodewaxate base stock and at least one performance additive thus permitting a reduction in the volume of lubricant used and a concomitant reduction in the size of the lubricant reservoir and related equipment.

  • Publication number: 20080176775
    Abstract: Methods for achieving favorable efficiency properties are disclosed including methods for blending a lubricant composition and lubricant compositions. In one embodiment, the method comprises the steps of obtaining at least one base stock and at obtaining at least one base stock chosen to have a favorable air release properties, obtaining at least one additive, blending at least one base stock and at least one additive to achieve a favorable effective bulk modulus through air release property, bulk modulus, and using a relationship between density and bulk modulus.

  • Patent number: 5372033
    Abstract: A method and apparatus for measuring thickness and traction properties of elastohydrodynamic lubricant (EHL) films is described. The apparatus utilizes at least one ball or roller loaded against the internal diameter of a transparent ring having a larger radius than said ball or roller. A lubricant is placed between the rotating roller and ring thereby forming an EHL film where the ball and ring contact. Roller and ring rotating speeds are controlled to obtain different amounts of relative sliding motion between their surfaces. Contact between the surfaces and the resultant film are observed via the transparent ring which allows optical measurements of lubricating film thickness. Traction forces generated during contact are measured by any suitable force measuring device.
