The Clean Energy Process
The key concepts behind a BNL Clean Energy plant are patented. Having said that, our thermo-chemical process takes its starting point in three already established technologies: pyrolysis, gasification and catalytic reaction (Fischer-Tropsch process). When we combine these actions in a closed loop under high pressure (20 bar,)we achieve the smaller scale and the Zero Emission process which make our company unique.
Feedstock arriving at our plants tends to be voluminous and humid. For this reason, it is dried and compressed before the so called pyrolysis begins. Here the input is exposed to heat up to the point where only two things remain, gases and coke, i.e. pure carbon. In the following stage, this coke is gasified with pure oxygen. This takes place at temperatures far above 700°C. As a result we avoid the creation of CO2, a greenhouse gas which causes global warming if it is released into the atmosphere.
The gas created through pyrolysis and gasification is called syngas and obviously very hot. With this heat we can run a turbine, in order to generate electricity. While we are cooling it down, we lead the syngas through heat exchangers whereby we achieve for example central heating.
The final step of a BNL Clean Energy plant is a so called Fischer-Tropsch reaction. Here the syngas enters into a catalyst where it is transformed into synthetic hydrocarbons. This last stage is absolutely essential for our Zero Emission Zero Residue Clean Energy technology. Interestingly, it gives you sellable commodities, like for example synthetic diesel or wax.
As you see, we recuperate and recycle. With BNL Clean Energy plants, a sustainable society becomes viable.
