Global isobutane (i-C₄H₁₀) production in 2025 is estimated at 60 to 100 million tonnes, reflecting its role as a widely used light hydrocarbon integrated into refinery operations, natural gas liquids (NGL) processing and petrochemical value chains. Supply growth is driven by rising LPG consumption, refinery alkylation demand, refrigerant substitution trends and petrochemical feedstock requirements.
Market conditions balance steady base demand with regional volatility linked to crude oil prices, natural gas production levels and refinery operating rates. The global picture shows stable capacity growth aligned with NGL expansion in shale-rich regions and incremental refinery upgrades rather than greenfield standalone projects.
Production leadership remains concentrated in North America, Middle East, Russia, China and Europe, where large-scale refining and gas processing infrastructure supports consistent output. Many import-dependent regions rely on LPG trade flows to meet domestic demand.
Buyers value supply reliability, purity specifications and contract-linked pricing visibility.
Refrigerant and petrochemical grades dominate value growth, while fuel blending accounts for the largest volumes globally.
Isomerisation capacity is critical for meeting refinery alkylation demand, while NGL recovery defines supply elasticity in gas-producing regions.
Fuel and refining uses dominate volume, while refrigeration drives regulatory-led growth due to low global warming potential (GWP).
Strong growth supported by shale gas production, extensive NGL infrastructure and refinery alkylation capacity.
Stable supply linked to integrated refining and gas processing complexes with export-oriented LPG trade.
Rising demand from refrigeration manufacturing, petrochemicals and LPG consumption.
Moderate growth driven by refrigerant transition policies and refinery optimisation.
Growing LPG demand but limited local upgrading capacity, increasing import reliance.
The isobutane supply chain begins with gas processing or refinery isomerisation, followed by fractionation, storage and distribution via pipelines, pressurised vessels and marine transport. Downstream buyers include refiners, refrigerant manufacturers, aerosol producers and fuel distributors.
Crude oil and natural gas prices, refinery utilisation rates and logistics costs dominate pricing. International trade is significant, with LPG carriers enabling interregional balancing.
The isobutane ecosystem includes gas producers, refiners, petrochemical companies, refrigerant manufacturers, LPG traders and regulators. Strategic themes centre on feedstock optimisation, regulatory compliance for refrigerants and infrastructure resilience.
