The typical mass balance output from one ton of mixed polyolefin plastic entering the process is approximately 82% hydrocarbon distillate, 4% char, 4% losses in the desulphurization process, 4% losses of non-condensable gases and 6% which is captured and displays similar properties to commonly available .white spirit. or degreaser. The non-condensable gases from the Thermo Fuel plant are passed through a water scrubber and then fed back into the natural gas flow to the thermal oxidiser, which heats the unit, meaning there are minimal net hydrocarbon emissions.
The hydrocarbon fraction in turn comprises approximately 75% distillate cut and 25% paraffin material. The paraffin fraction is continuously cracked after the first condenser until it reaches the desired chain-length range and then added to the primary fuel stream. A comparison of the distillate produced from a commingled plastic mix compared with regular diesel has been conducted by gas chromatography, and shows excellent similarity between Thermo Fuel and refinery produced diesels.
