OIL AND GAS FIRED PROCESS HEATERS
Reduce Emissions
Increase Efficiency
Restore Capacity
Therma-Chem have been cleaning process
heaters online throughout the world for over 30 years. FS12, our unique alkali solution, is injected into the radiant section and disperses throughout the heater removing deposits from all heat transfer surfaces increasing efficiency, preventing corrosion and reducing emissions.
FS12 will reduce bridgewall temperatures, eliminate Vanadium Pentoxide corrosion and prevent dew-point corrosion in the air pre-heaters and economisers.

Therma-Chem’s FS12 is an mildly alkaline solution containing nitrates that is designed specifically to clean process heaters online. Using Therma-Chem’s proprietary injection system, the liquid is injected directly into the combustion chamber, vaporises and is carried by the flue gas through the unit, encountering all heat transfer surfaces including the radiant section, convection section, air pre-heater and waste heat boiler.
FS12 reacts with existing hard deposits and fouling on tubes by increasing their melting point and reduces them to soft powdery ash.
This allows units to maintain high thermal efficiencies or recover capacity (if this was limited by fouling). FS12 also neutralises sulphur deposits on the cold end of the flue gas path preventing cold end corrosion and eases man entry during a maintenance or inspection shutdown.
In addition, FS12 will reduce NOx, SOx and Carbon emissions by up to 20%.
Using FS12 ultimately results in improved heat transfer, prevention of both high temperature and low temperature corrosion, improved operating efficiency and reduced emissions.
