The Competitive Edge: Sweet Gazoil Inc.
by Jim Lane (Biofuels Digest) … Sweet Gazoil (SGO) was founded with the goal of protecting the environment by providing cost-effective technologies to treat mixed waste plastics, heavy and used/waste oils, and other waste hydrocarbons. SGO has developed and patented an anti-fouling ultrafast pyrolysis technology (Surface Flash Cracking (SFC)) which is 10 times more efficient than traditional pyrolysis. Heavy and used/waste oils can be profitably transformed into saleable oil products, while mixed waste plastics can be processed into high quality ultra-low sulfur diesel (ULSD) with 4 times less greenhouse gas (GHG) emissions than ULSD originating from crude.
SGO has built and helped operate a demonstration unit to treat used oils that no other process could treat and is licensing the technology for oils. The SFC technology is now being globally marketed for the treatment of mixed waste plastics within small-scale cost-effective units (micro-refineries) at a reasonable cost and with negative GHG emissions.

SGO’s engineers specialise in various aspects of plastic and oil pyrolysis systems, such as Surface Flash Cracking, cracked fuel stabilisation and the design and operation of small scale distillation columns.
SGO offers engineering consulting for the treatment of plastics and heavy and used/waste oils into high quality fuels and saleable oil products. Other services include feasibility studies and strategic reviews for the treatment of heavy and used/waste oil, as well as plastic pyrolysis operations.

The SFC process starts with shredding and removing contaminants from the plastics. Then, the plastics are liquified and fed into our patented anti-fouling SFC reactor which treats plastics by projecting small droplets onto very hot surfaces that are self-cleaning. They react almost instantly and produce vapors which are quickly swept out of the reactor. Each drop absorbs only the amount of energy needed to crack, preventing over-cracking and producing right-sized hydrocarbons. After entrained solids are eliminated with cyclones and/or refluxing condensers, the vapors are sorted in a distillation column into pure marketable fuels. READ MORE
