Green Fuels has 17 years’ experience in developing the leading technology for biodiesel production. Through our own R&D and through listening to customers, we have developed systems that can convert a wide spectrum of feedstocks into the highest quality fuel exceeding international standards (ASTM6751 and EN14214). Our GFM operating system provides an easy to use interface with remote access to monitor operations, while sensors and field devices ensure the highest levels of efficiency within minimal operator input.

GSX Technology

Core to our system is our patented GSX separation technology.  This uses a simple, but unique, separation process with no moving parts, enabling safer and more reliable glycerol separation than traditional centrifuge-based systems.  This technology allows us to minimise the footprint of the equipment, providing systems that are truly mobile and modular. 

Safer recycling

As a standardised product the FuelMatic is CE/ATEX approvedsafety and compliance are built in.

  • Automated feedback loops ensure that if a component fails, the unit will shut down safely
  • Methanol is vacuum recovered and reused, minimising emissions and operating costs
  • Field devices are isolated, eliminating short circuiting on both ends of the system
  • Equipment is manufactured to enable easy manual inspection
  • Remote access allows quick and easy diagnostics and repair 

Easy to install and use

  • As a container frame or skid-mounted unit, the FuelMatic is transportable across the world using traditional shipping and re-commissioned on-site 
  • The only required utility is electricity; no water or steam is needed. The unit can be up and running extremely quickly 
  • The process is fully automated, with intelligent GFM software operated onsite via touch screen controls or via remote access 

How the FuelMatic works?

The feedstock is automatically fed into a pre-heat vessel where it is heated to the optimum reaction temperature.  The oil is then measured into the reaction vessels where methanol and methylate are accurately injected into the flow to ensure a quick and complete reaction. 

Once the reaction is complete the mixture of crude biodiesel and crude glycerine is channelled through to the GSX separation unit where the two products are cleanly separated, and the glycerine is then automatically discharged to storage. 

The crude biodiesel then passes through our purification process where any impurities are removed through a dry ion exchange process. 

Finally, the residual methanol is flashed and recovered though vacuum distillation for reuse in the subsequent cycle.  The resulting biodiesel is automatically discharged to site storage for use.
