  • Method for removing asphaltene deposits
    Patent number: 7754657
    Abstract: Compositions comprising at least one C4-C30 olefin or oxidation product thereof and kerosene or an aromatic solvent are particularly effective for use in removing asphaltene and asphaltene-containing organic deposits and in preventing or reducing the precipitation and deposition of asphaltenes from hydrocarbon fluids. When added to heavy oils comprising asphaltenes, alone or in combination with dispersants and further inhibitors, the invented compositions lower viscosity and pour point, and aid in preventing asphaltene precipitation during transport and in combustion.

  • REFRIGERATOR OR FREEZER WITH ENHANCED EFFICIENCY
    Publication number: 20100043463
    Abstract: A refrigerator or a freezer comprises a primary refrigeration system (11) which is augmented with a passive secondary refrigeration loop (15) having a condenser (30) in thermal contact with a primary fluid line (12) at the location between a primary compressor (16) and a primary condenser (18) and preferably placed outside a building so that the passive secondary refrigeration loop (15) provides cooling to the primary refrigeration system (11) when the outside temperature is sufficiently low The condenser (30) of the passive secondary refrigeration loop (15) is positioned above the points where the primary fluid line (12) connects with mlet (32) and outlet (34) lines of the secondary loop condenser (30)
