Definitions

  • the present invention relates generally to flare tips employed in the petrochemical industry for burning off-gases associated with the production and/or refining of petroleum-based products.
  • the present invention relates to flare tips coated with a low emissivity (low-E) material so as to improve the longevity and performance thereof.
  • low-E low emissivity
  • Flare tips are notoriously well known in the petroleum industry and are used typically to burn off-gases associated with petroleum production and/or refining. US 7 247 016 describes such a flare tip. Flare tips are therefore exposed to direct flame during their service life which can of course be quite damaging. As a result, flare tips need to periodically be taken out of service and refurbished which adds to production costs.
  • EP 0,139,353 (A1 ) describes an improved burner which is suitable for use in a ground flare.
  • the present invention is directed to applying a low emissivity (low-E) coating onto flare tips to achieve longer flare tip service life, improved flare tip structural integrity and/or a more stable flame pattern under a wide range of operating conditions.
  • low-E coatings may be applied to the flare tip burner as well as associated internal and/or external component surfaces to reduce direct flame radiation and also conductive heat transfer.
  • the low-E coating material has an emissivity of less than about 0.80, preferably between about 0.20 to about 0.78.
  • the coating thickness of the low-E material is preferably between about 0.0254 mm (1 mil) to about 0.635 mm (25 mils), and more preferably between about 0.0508 mm (2 mils) to about 0.2032 mm (8 mils).
  • Coating densities of the low-E material in the coating will preferably be at least about 65%, more preferably between about 80% to about 100%.
  • the improved flare tips in accordance with the present invention therefore result in significantly less deformation and distortion of the flare tip burner as well as its associated internal and/or external components thereby prolonging its useful service life.
  • the low-E ceramic coatings of the present invention will also provide enhanced corrosion and oxidation resistance and further improve the longevity of the flare tip burner as well as its associated internal and/or external components.
  • FIGURE 1 is a perspective view of an exemplary flare tip in accordance with the present invention.
  • a low emissivity (low-E) coating material is applied to the flare tip burner as well as associated internal and/or external component surfaces to reduce direct flame radiation and also conductive heat transfer.
  • An exemplary flare tip 10 is depicted in accompanying FIGURE 1 as having a flare barrel 12 which terminates in a baffled burner element 14.
  • Flame stabilization tabs 16 are provided at circumferentially spaced-apart locations about the burner element 14 so as to ensure stable and high efficiency flaring through a range of gas flows.
  • all exterior and interior surfaces of the flare tip 10 which may have exposure to the flame and its attendant radiation are coated with a low-E ceramic material. Coated structures therefore include, for example, at least an upper portion of the flare barrel 12, the burner element 14, and/or the stabilization tabs 16.
  • the emissivity (E) of a material is meant to refer to a unitless number measured on a scale between zero (total energy reflection) and 1.0 (a perfect “black body” capable of total energy absorption and re-radiation).
  • a relatively low emissivity (low-E) is meant to refer to coating materials having an emissivity of less than about 0.80, and especially materials having an emissivity of between about 0.20 to about 0.78.
  • one presently preferred low-E ceramic coating includes CERAK M700 ceramic coating commercially available form Cetek, Ltd..of Berea, Ohio, having an emissivity of about 0.75.
  • Coating thicknesses of the low-E ceramic coating material are not critical but will vary in dependence upon the desired resulting thermal flux and/or the particular material forming the coating. Thus, coating thicknesses of from about 0.0254 mm (1 mil) to about 0.635 mm (25 mils), usually about 0.0508 mm (2 mils) to about 0.2032 mm (8 mils) may be appropriate. Coating densities will typically be greater than about 65%, more specifically 80% or greater. Coating densities will typically be greater than about 65%, more specifically 80% or greater, including up to 100%. By “coating density” is meant the amount (wt.%) of the low-E ceramic coating material that is present in the coating.
  • the low-E coating material may be applied to flare tip components in any conventional manner.
  • the low-E coating material may thus be applied to the flare tip components via any pressurized spray system while the flare tip is being manufactured or while off-line (i.e., is not at its operational temperatures) during refurbishment.
  • a high temprerature low-emissivity coating (CETEK M720 high-temperature ceramic coating having an emissivity value of about 0.75) was applied to a flare tip manufactured by Callidus Technologies LLC.
  • the low-E coating utilized a non-toxic, non-flammable carrier, with a high temperature ceramic binder and was sprayed onto the flare tip structures to be exposed to direct flame during operation by conventional spray equipment.
  • the sprayed coating was thereafter allowed to dry in air for 4 hours and cured at 815 °C (1500°F). After curing, the coating on the flare tip surfaces exhibited a thickness of about 3 mils at a coating density of the low-E material of about 100%.
  • the coating was intended to provide excellent thermal barrier protection, oxidation and corrosion resistance to metallic substrates at elevated temperatures up to 1315 °C (2400°F), as well as a reduction in warpage, stress corrosion cracking, and alloy leaching.
  • the coating also was intended to provide uniform heat distribution for enclosed flare systems.
  • the flare tip with the low-E coating material applied thereto was placed into service to burn off-gases. After approximately six months of continuous operation, the condition of the coated flare tip surfaces was visually inspected and determined to be satisfactory indicating that the coating material provided protection against the direct flame during flare tip operation.
