Description
- 1 LONGEVITY AND PERFORMANCE IMPROVEMENTS TO FLARE TIPS FIELD OF THE INVENTION 5 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. In especially preferred forms, the present invention relates to flare tips coated with a low emissivity (low-E) material so as to improve the longevity and performance thereof. 10 BACKGROUND 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. 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 i5 periodically be taken out of service and refurbished which adds to production costs. It would therefore be highly desirable if the service life of flare tips could be extended. It would also be especially desirable if the performance characteristics of flare tips could be enhanced. 20 SUMMARY OF THE INVENTION Broadly, 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. In accordance with some embodiments of the 25 present invention, low-E coatings may be 2707363v1GHMatters - P78501.AU 17/06/11 2707383_1 (G~mMIerS) P78501 AU WO 2007/085793 PCT/GB2007/000068 -2 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. In accordance with some embodiments of the invention, the low-E 5 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 1 mil to about 25 mils, and more preferably between about 2 mils to about 8 mils. Coating densities of the low-E material in the coating will preferably be at least about 65%, more 10 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 15 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. These and other aspects and advantages will become more apparent after careful consideration is given to the following detailed 20 description of the preferred exemplary embodiments thereof. BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS Reference will hereinafter be made to the accompanying drawings, wherein like reference numerals throughout the various FIGURES denote like structural elements, and wherein; WO 2007/085793 PCT/GB2007/000068 -3 FIGURE 1 is a perspective view of an exemplary flare tip in accordance with the present invention. DETAILED DESCRIPTION OF PREFERRRED EMBODIMENTS According to a presently preferred embodiment of the present 5 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 10 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. According to especially preferred embodiments of the present invention, all exterior and interior surfaces of the flare tip 10 which may have exposure to the flame 15 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. As used herein, the emissivity (E) of a material is meant to refer to 20 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). According to the present invention, 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 25 having an emissivity of between about 0.20 to about 0.78.
WO 2007/085793 PCT/GB2007/000068 -4 Virtually any commercially available low-E coating material may be employed satisfactorily in the practice of the present invention. For example, one presently preferred low-E ceramic coating includes CERAK M700 ceramic coating commercially available form Cetek, Ltd. of Berea, 5 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 1 mil to about 25 mils, usually about 2 mils to 10 about 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 15 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 20 operational temperatures) during refurbishment. The present invention will be further understood from the following non-limiting Example. EXAMPLE A high temprerature low-emissivity coating (CETEK M720 high 25 temperature ceramic coating having an emissivity value of about 0.75) was applied to a flare tip manufactured by Callidus Technologies LLC.
- 5 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 5 1500 0 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 2400 0 F, as well as a reduction in warpage, stress corrosion cracking, and alloy io 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 is and determined to be satisfactory indicating that the coating material provided protection against the direct flame during flare tip operation. While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, 20 but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country. 25 In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features 30 in various embodiments of the invention. 2707363v1 GHMatters - P78501.AU 17/06/11 2707363_1 (GHMatterS) P78501 AU
