  • Publication number: 20150111799
    Abstract: The present invention relates to the use of a chemical composition to modify the physical properties (viscosity and interfacial tension) of heavy and extra-heavy crude oils, to increase their mobility. The chemical composition comprises or consists of a combination of systems based on ionic and non-ionic liquids, which may be pure or modified, mixed in an aqueous or organic medium as a dispersing agent, depending on the nature of the crude to be treated, together with a surfactant. The composition is mixed with the crude oil at a temperature between 5 and 100° C., at pressures from 1 atm (14.7 psi) up to about 680.2 atm (10,000 psi). The composition can be mixed with heavy crude oils, at the point of extraction from the well in the field, during the transport of crude oil in pipelines, or in the well discharge pipelines.

  • Publication number: 20110306429
    Abstract: The present invention provides a grease composition or a lubricating oil composition which is capable of effectively preventing hydrogen brittleness-caused peeling from occurring on a rolling surface of a rolling bearing, is excellent in durability in a high temperature and speed operation, and can be used for a long time. A grease-packed bearing (1) has an inner ring (2), an outer ring (3), and a plurality of rolling elements (4). A sealing member (6) for sealing a grease composition (7) is provided at openings (8a) and (8b) disposed at both axial ends of the inner ring (2) and the outer ring (3). The grease composition (7) includes a base grease composed of a base oil and a thickener and an additive added to the base grease. The additive contains at least one compound selected from among plant-derived polyphenolic compounds and compounds formed by decomposition thereof.

  • Publication number: 20110098203
    Abstract: A lubricant composition for a resin conveyor, comprising specific (A) a nonionic surfactant and (B) water and, if necessary, (C) (a) a cationic surfactant and/or (b) an amphoteric surfactant, and a method for using same. Using a specific nonionic surfactant as the main component provides excellent washing ability, lubricating ability, and stability in storage. In particular, because excellent ability to prevent stress cracking is attained, the lubricant composition for a resin conveyor can be advantageously employed for transporting PET containers. Furthermore, adding a specific cationic surfactant makes it possible to obtain a lubricant composition for a resin conveyor also demonstrating an effect of inhibiting microorganism (fungi) generation, without degrading the various original performances (effects). Furthermore, a preferred method for using those lubricant compositions for resin conveyors is also provided.
