The main engine of oil chemistry equipment with plastic wastes deployed in Chinese mainland, mainly uses vertical fixed processor with processes below: first, the plastic wastes are put via the cracking processor top by the operator; second, seal the feed inlet and the processor bottom will slowly heat the wastes with coal or firewood left as the fuel. Generally, the cracking processor has a volume with 5 stere and one-ton feed. Thus, it usually takes 12 hours to refine once. After the process is completed, it is required to cease for another 12 hours. Then the taphole at the bottom of the processor will be opened for dumping the dreg after the processor cools down; the material will be fed from the processor inlet and then enters to next circulation.    

The vertical oil-refining processor in China cannot meet environmental protection requirements on its disposal of three wastes during manufacturing; besides, it doesnt have capability to produce continuously. Thus, to fulfill the economic benefits will require more oil-refining processors to work together.
