FCC METHOD FOR PRODUCING AN ANTI-EROSION COATING ON AN INNER WALL OF A CHAMBER OF AN FCC UNIT AND ANCHORING STRUCTURE FOR PRODUCING SAID COATING

摘要

The present invention relates to a method of producing a corrosion resistant coating on an inner or outer metal wall (20) of a fluid catalytic cracking unit chamber. (i) forming a honeycomb metal anchoring structure 10 from a plurality of strips 12 connected in pairs to form a plurality of compartments 14 between two adjacent strips; (Ii) the anchoring structure is welded such that each compartment 14 of the anchoring structure 10 is welded to the wall 20 of the chamber at the point of intersection between adjacent assembly portions 121, 122 of two adjacent strips 12. Securing to the metal wall (20); And (Iii) injecting the composite material 22 into the compartment 14 of the anchoring structure 10 from the metal wall 20 to at least the upper longitudinal edge 12b of each strip. .
