Technology

Pyrolysis is a thermochemical decomposition or cracking of organic material at elevated temperatures inside a closed chamber where oxygen is removed and not allowed. Component of plastic is 60-80 % petroleum; thereby through pyrolysis technology, the petroleum component of the plastics could be recovered instead of burying in the landfills.

The waste plastic are shredded to smaller size at 1 to 3 inches cut and at the same time some of the impurities are loosened through the fast rotary impingement inside the machine and finally removed to discharge screening auxiliaries. Six (devil) to ten (10) tons of pre-treated plastic (depending on compactness of feeding) are placed inside to the rotary reactor and closed to prevent the influx of oxygen. This rotary reactor is heated up to 600ÂșC for efficient cracking of the petroleum component of the plastics and evaporates continuously while thermochemical cracking is taking effect to its original form as petroleum.

The evaporated gas is liquefied again into petroleum fuel (known as plastic oil) through condensation process of cooling water system. Some of the light petroleum formed into methane and became none condensable, thereby returned back to heating chamber of the reactor and used as heating fuel. Plastic oil is packed with 9,500KJ per kilogram energy and could be the cleanest fuel oil with only .005% sulphur content. It has more or less 8 % less energy than conventional automotive diesel fuel and bunker oil but far better than bunker oil in terms viscosity, ash content, and emission quality.
