DOING plastic pyrolysis plant project report

With the rapid development of the world plastic industry, more and more plastic materials are used widely than before. As the increasing quantity application of plastic, it brings people convenience as well as serious pollution problems. At present, the waste plastics mainly are solved by landfill, burning and recycling. However, both of landfill and burning cause the secondary pollution, and the scope plastic recycling is very limited. For example, the waste plastics produced by household garbage and paper-making factory, which can not be recycled. With the increasing price of International crude oil, plastic pyrolysis plant project report is closely watched by different countries in the world.

Waste plastic usually takes the pyrolysis technology to do recycling usage. Pyrolysis technology is the industrial process of breaking down large molecules of plastic/tires into smaller molecules of oil,gas and carbon black.The pyrolysis technology of waste plastic not only no pollution to the environment but also recycle the energy effectively.That is to say, plastic pyrolysis technology is the inverse process of manufacturing plastic products by crude oil materials.Our DOING company add different catalyst to the different plastic materials for pyrolysis. Compared with  other plastic pyrolysis plant design,we improve the oil yield and quality.

Because the plastic is made of different raw material, the plastic pyrolysis process is also a little different. PE,PP and PS are decomposed at 300-400 centigrade degrees. But the PVC is decomposed at two stages which are 200-300 and 300-400 centigrade degrees. The PVC may release HCL and hydrocarbon,and then break down step by step. Due to the corrosivity of HCL,and it will effect the pyrolysis catalyst, life span and the oil quality.Then the pyrolysis technology requests that the PVC should be less than 30% of the waste plastic.
