    摘要: The present invention is directed to a method for protecting metal surfaces in oil & gas exploration and production, refinery and petrochemical process applications subject to solid particulate erosion at temperatures of up to 1000° C. The method includes the step of providing the metal surfaces in such applications with a hot erosion resistant cermet lining or insert, wherein the cermet lining or insert includes a) about 30 to about 95 vol % of a ceramic phase, and b) a metal binder phase, wherein the cermet lining or insert has a HEAT erosion resistance index of at least 5.0 and a K1C fracture toughness of at least 7.0 MPa-m1/2. The metal surfaces may also be provided with a hot erosion resistant cermet coating having a HEAT erosion resistance index of at least 5.0. Advantages provided by the method include, inter alia, outstanding high temperature erosion and corrosion resistance in combination with outstanding fracture toughness, as well as outstanding thermal expansion compatibility to the base metal of process units. The method finds particular application for protecting process vessels, transfer lines and process piping, heat exchangers, cyclones, slide valve gates and guides, feed nozzles, aeration nozzles, thermo wells, valve bodies, internal risers, deflection shields, sand screen, and oil sand mining equipment.

    摘要: A tile for lining an internal surface in a heavy wear area. The tile includes at least one locating rod embedded within said tile and an internal mechanism for laterally extending said at least one locating rod out of said tile and into a gap in an adjoining structure which may be another tile. The tiles forming the lining surface are securely held in place as a result of the selective deployment of the locating rods into a gap in the adjoining structure.

    摘要: A process for separating a feed mixture of zirconium and petroleum coke containing traces amount of radioative materials by flotation process utilizing a plurality of flotation cells. The process comprises grinding the feed mixture, slurrying the ground feed mixture with water, treating the slurry with a flotation agent and a collector for the coke and subjecting the treated slurry to air sparging and agitation to create an overflow and an underflow. The overflow is then filtered to collect substantially zircon-free coke for further processing.
