Fuel Management Technology

Spain`s Fuel Management Technology is one of the most reputable manufacturers of gasoline recycling machines, which is able to build modern gasoline recycling systems at fuel stations with international patents.

The company’s machines and equipment are capable of converting vapor of petrol and volatile organic matter into high-octane fuel. This cycle, due to avoiding waste of vapors, while taking advantage of environmental benefits, also results in a significant reduction in environmental pollutants.

It is worth noting that the Corrosion Science Technology, as the first executor of the project, honors the exclusive and exclusive representation of the Spanish FMT Company.


Oxidation of hydrogen sulfide and mercaptan on the THIONOL catalyst takes place in hydrocarbon media directly, and can be set in refinery product ion line, buffer tanks, settlers and storage tanks. Unlike many known processes THIONOL does not require water caustic which allows us to propose caustic free technology of hydrogen sulfide and mercaptan removal.

CST as an exclusive representative of NEFTESINTEZ Company is able to provide THIONOL catalysts with the highest quality for sweetening and desulfurization in gas and liquid phase.
