    Abstract: A heat transfer component that is resistant to corrosion and fouling is disclosed. The heat transfer component includes a heat exchange surface formed from a chromium-enriched oxide containing material formed from the composition δ, ε, and ζ, wherein ζ is a steel containing at least about 5 to about 40 wt. % chromium, ε is a chromium enriched oxide (M3O4 or M2O3 or mixtures thereof) formed on the surface of the steel ζ, wherein M is a metal containing at least 5 wt. % Cr based on the total weight of the metal M, and δ is a top layer formed on the surface of the chromium-enriched oxide ε, comprising sulfide, oxide, oxysulfide, and mixtures thereof. The top layer δ comprises iron sulfide (Fe1-xS), iron oxide (Fe3O4), iron oxysulfide, iron-chromium sulfide, iron-chromium oxide, iron-chromium oxysulfide, and mixtures thereof. The metal M of the chromium enriched oxide (M3O4 or M2O3 or mixtures thereof) may comprise Fe, Cr, and constituting elements of the steel ζ. The steel ζ may be selected from low chromium steels, ferritic stainless steels, martensitic stainless steels, austenitic stainless steels, duplex stainless steels and precipitation-hardenable alloys.

    Abstract: The present invention provides for a method of decreasing the metals content of metal containing petroleum streams by forming a mixture of the petroleum fraction containing those metals and an essentially aqueous electrolysis medium, and passing an electric current through the mixture at a voltage, pH and time sufficient to remove the metals such as Ni, V and Fe from the stream (i.e. to produce a petroleum fraction having decreased content of the metals). The cathodic voltage is from 0 V to -3.0 V vs. SCE at a pH of from 6 to 14, preferably 7 to 14, most preferably above 7 to 14.The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their Ni and V content.

    Abstract: This invention provides a process for separating solute material from an algal cell feed stream. The algal cell feed stream, which contains the solute material, can be introduced into on portion of a mixer-settler vessel, and a solvent feed stream can be introduced into another portion of the vessel to mix with the algal cell feed stream, with a goal of separating at least a portion of the solute material from the algal feed stream.

    Abstract: Targeted application of anti-fouling mechanisms in a heat exchange system produces higher rates of energy recovery. The anti-fouling mechanisms with high mitigation rates can be deployed at only the hottest portions of a pre-heat train that experience the highest rates of fouling and heat loss. In application, bundles of corrosion resistant smoothed tubes are deployed in the late pre-heat train to significantly reduce the formation of harder deposits. Vibration can be used as an adjunct approach in conjunction with the corrosion resistant, smooth tubes, or deployed alone on existing bundles. The use of high performing, more durable exchangers in select locations justifies the increased cost of these components.
