De Fuel

De Fuel is an innovative method of plastic material transformation by way of a thermo-catalytic de-polymerisation process allowing to derive fuel oil at low costs. Using packaging, manufacturing waste and urban waste as raw material, the system extracts paraffin-based fuel oil with optimal yield, equal to one litre of fuel for every kilogram of plastic processed by the system.

The raw material feeding the De Fuel system consists of plastic material mostly derived from the following:

   Polyethylene (HDPE e LDPE)

   Polypropylene (PP)

   Polybutadiene (PBD)

   Polystyrene (PS)

The fuel obtained by a De Fuel system features a Lower Calorific Value (LCV) higher than 40,000 kJ/kg, it is sulphur-free and ready to produce electrical and/or thermal power.

De Fuel was designed by Demont between 2010 and 2013, entirely with company resources; it is the result of a long research, development and industrialisation process.

The De Fuel system is comprised of small modules, as big as standard 20″ containers, which may be handled by ordinary freight. The system as a whole is made up of three modules, two resting on the ground and one placed above them. The De Fuel installation process does not require any significant engineering operations and takes little space, usually available within existing plants. All this translates to extremely short installation time.

The macroeconomic indexes regarding De Fuel describe it as an extremely attractive investments, which stands out for a very short return time and a rate of return (IRR) that is absolutely remarkable.

SYSTEM PERFORMANCE

Following is a summary of the normalised overall yield on 100 kg of input polyolefins. Value variability on different batches of products results from the tests made at different feed and temperature conditions.

RAW MATERIAL FED INTO THE SYSTEM:

– Dry polyolefins = 100 kg

– Catalyst = 2-5 kg

PRODUCTS AND BY-PRODUCTS OUT OF THE SYSTEM:

– Fuel oil = 70-85 kg

– Non condensible gas = 10-20

– Solid residue = 5-10

Considering the different composition of the feed load, the measurement errors, the material lest into the system, the humidity of the input plastic and the inert catalyst component found in the solid by-product out from the evaporator, the following yields were calculated with a ±10% error:
