Applications
Select an application to see how OxiTherm thermal oxidisers address your specific petrochemical emission control needs.
Petroleum refining generates complex off-gas streams from catalytic crackers, cokers, hydrotreaters, and reformers — containing C1–C6 hydrocarbons, H₂S, mercaptans, and BTEX compounds. These emissions are subject to IED BAT-AEL, EPA MACT, and NSPS Subpart Ja limits. Our OxiTherm regenerative thermal oxidisers destroy 99%+ of refinery VOCs at 850–1,100°C with 2.0-second residence time, handling variable composition and flow from multiple process vents simultaneously — providing a reliable, permitted alternative to elevated flares.

Operations
Key advantages of OxiTherm regenerative thermal oxidisers for petrochemical VOC and off-gas emission control.
99%+ VOC Destruction
Regenerative thermal oxidation at 850–1,100°C destroys BTEX, alkanes, H₂S, and mercaptans — meeting IED BAT-AEL, EPA MACT, and NSPS emission limits.
98% Energy Recovery
Ceramic heat exchange media captures and returns 98% of combustion energy — enabling near-autothermal operation on hydrocarbon-rich refinery off-gas streams.
ATEX Zone 1/2 Rated
Full ATEX/IECEx certification for installation in hazardous areas — explosion-proof instrumentation, flame arrestors, and LEL monitoring as standard.
Flare Replacement
Enclosed ground-level combustion eliminates visible flame, smoke, noise, and light pollution — satisfying community concerns and tightening permit conditions.
Multi-Stream Capable
Single system handles combined off-gas from process vents, tank farms, loading racks, and wastewater treatment — reducing capital cost versus separate abatement.
Continuous Monitoring
Integrated CEMS with real-time VOC, CO, O₂, and H₂S monitoring — providing audit-ready compliance records for IED Article 68 and EPA reporting.
Turn Waste Gas
Into Energy
Refineries and petrochemical plants consume massive amounts of steam and process heat. Our oxidisers recover energy from waste gas destruction — offsetting utility costs.
Recovered Energy Offsets
Your Utility Costs.
Petrochemical sites run massive steam networks, fired heaters, and heat transfer systems. The OxiTherm doesn't just destroy your waste gas — it captures 98% of that combustion energy and routes it into your existing utility infrastructure. The result: your emission control system generates a return instead of just being a compliance cost.
A waste-heat boiler generates 4–10 bar(g) steam from oxidiser exhaust — supplementing your existing boiler plant and reducing fired boiler fuel consumption by 10–25%.
Recovered heat pre-heats process feed streams, reboiler circuits, and column bottoms — displacing fired heater duty and reducing the thermal load on your furnace fleet.
A secondary heat exchanger raises thermal oil return temperature — reducing the firing rate on dedicated hot oil heaters serving reactors, distillation, and storage tank heating.
Recovered energy pre-heats combustion air for adjacent process furnaces and boilers — improving their thermal efficiency by 3–8% and reducing stack losses.
