Contrive Datum Insights has published "Refining Additive Market Size, Share & Industry Analysis, By Type (Corrosion Inhibitor, Stabilizers, Hydrogen Sulfide Scavenger, Antioxidants, Antifoulants, Defoamers, Catalyst Regenerators, Biocides, Amine Solutions, Cetane number improver), Application (Crude Oil Processing, Fluid Catalytic Cracking, Hydroprocessing), Form (Liquid, Solid/Powder, Gel/Paste), End user (Petroleum Refineries, Petrochemical Plants, Gas Processing Plants), Distribution channel (Direct Sales, Distributors), and Regional Forecast, 2026-2034". The study sizes the global refining additive market at USD 8.6 billion in 2025 and projects growth from USD 9.15 billion in 2026 to USD 14.27 billion by 2034, a compound annual growth rate of 5.71% across the forecast period.
Refining additives are specialty chemical formulations added at precise dosing points across a petroleum refinery to protect equipment, stabilize intermediate and finished streams, and help catalytic units run within their intended operating range. They take the form of liquid concentrates, solid or powder blends and, less commonly, gels or pastes, and are typically injected continuously rather than applied as a one-time treatment. Buyers are refinery process and reliability engineering teams, procurement departments at integrated oil companies and independent refiners, and, to a smaller extent, petrochemical and gas processing operators running comparable units.
Rising processing of sour and heavy crude grades
Rising processing of sour and heavy crude grades is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 5.71% a year, the type lines exposed to it move fastest: Hydrogen Sulfide Scavenger compounds at 8.31%, taking its share of revenue from 11.98% to 15% and its value from USD 1.03 billion to USD 2.14 billion.
The study also runs a bull case: sour and heavy crude processing expands faster than the base case assumes, and announced Asia Pacific and Middle East refinery capacity additions proceed on or ahead of schedule. That path ends 2034 at USD 15.7 billion, above the USD 14.27 billion base case.
Against that, refinery closures and rationalization in mature markets proceed faster than announced, and new capacity additions in Asia Pacific and the Middle East slip behind their public schedules. On that reading 2034 revenue stops at USD 12.84 billion. The weight of the problem sits in Corrosion Inhibitor: 18.95% of 2025 revenue growing at 5.07%, well under the market's 5.71%.
The Competitive Split Runs by Type
Competition in the global refining additive market runs along the type axis, not the regional one. Corrosion Inhibitor holds 18.95% of 2025 revenue at USD 1.63 billion and remains the largest line through 2034 at 18.01%, making it the position hardest for a challenger to take. Hydrogen Sulfide Scavenger, growing at 8.31%, is where share actually changes hands. A supplier established in one is not thereby established in the other, so a field of this size persists in a market of USD 8.6 billion.
