Steam Cracker Furnace Decoking: Market Size & Forecast 2026

The global steam cracker furnace decoking market sits at approximately USD 450 million in 2025 (base year), anchored to over 3,000 active steam cracking furnaces worldwide that require decoking cycles every 20 to 60 days to maintain thermal and hydraulic efficiency. The market operates as a mature, operationally critical MRO service bucket where ethylene plant operators treat decoking as a non-discretionary maintenance line item, driving a supplier-favoring buyer power score of -2.0 on the -5.0 to +5.0 scale. Growth through 2032 is pegged to a 3.5 percent CAGR, modest by category standards because the installed furnace base is stable and cycle-frequency optimization efforts are beginning to extend run lengths, partially offsetting the unit-count growth from new cracker builds, particularly in the Middle East and Asia-Pacific. > Synthesized from secondary and publicly verifiable sources v
