1. A hydrocarbon fluid comprising an organometallic chemistry-based compound for preventing coke formation in a hydrocarbon fluid system, the organometallic chemistry-based compound being present in the hydrocarbon fluid and including:
a coordination complex of at least one of M(N-butylsalicylaldimino)n, M(N-phenylsalicylaldimino)n, M(3,5-diisopropylsalicylato)n, [(N-butylphosphonium)mM(dimethylglyoxime)]n+, or M(bis-dithione)n, wherein the organometallic chemistry-based compound interrupts an autoxidative pathway of the coke formation under a temperature ranging between two hundred thirty to four hundred thirty deg. C.,
wherein M comprises at least one of Ni, Co, Fe, Cu, Zn, V, Re, Pt, Pd, Os, Ru, Cr, Mo, or W,
wherein n is 2 or 3, and
wherein the organometallic chemistry-based compound is released into the hydrocarbon fluid by a controlled release assembly.
