    摘要: A method for inhibiting corrosion under insulation (CUI) on the exterior of a structure, e.g., pipelines, piping, vessels and tanks, is provided. The method involves providing a structure that is at least partially formed from a corrosion resistant carbon steel (CRCS) composition. The CRCS composition includes corrosion resistance alloying additions in the amount of 0.1 weight percent to 9 weight percent. At least one alloying addition has a low free energy of formation for its oxide and/or hydroxide, e.g., vanadium and/or titanium. A corrosion inhibited structure that includes a structure at least partially formed from a corrosion resistant carbon steel (CRCS) composition, and insulation positioned around at least a portion of the structure.

    摘要: In one aspect, the invention includes a reactor apparatus for pyrolyzing a hydrocarbon feedstock, said apparatus including: a reactor component comprising a refractory material in oxide form, the refractory material having a melting point of no less than 2060° C. and which remains in oxide form when exposed to a gas having carbon partial pressure of 10−22 bar and oxygen partial pressure of 10−10 bar, at a temperature of 1200° C.; wherein said refractory material has no less than 4 vol % formed porosity, measured at 20° C., based upon the bulk volume of said refractory material. In another embodiment, the refractory material has total porosity in the range of from 4 to 60 vol %.
