Plastic Pyrolysis Plant Project Report

3D Waste Plastic Pyrolysis Plant

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, waste plastic pyrolysis plant project report  is closely watched by different countries in the world.

plastic waste recycling

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 the domestic pyrolysis technology,we improve the oil yield and quality.

Because the plastic is made of different raw material, the 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.

Pyrolysis Process Of Waste Plastics 

Flowing Chart Of Plastic Pyrolysis Plant

The molecules of different plastic is very different,so the final product and oil yield is different.Generally,there are four kinds of final pyrolysis products: hydrocarbon gas (C1-C5), oil (gasoline is C5-C11,diesel oil is C12-C20,the heavy oil is C20), paraffin and coke.

Features of Beston Plastic Pyrolysis Machine

(1)High quality: all of our plants have passed CE, ISO, SGS certification.

(2)High oil output: unique catalyzer and condenser which can increase oil yield by another 5% and improve oil quality.

(3)High efficiency: the reactor of the plant is 360-degree rotating and its rotate speed can reach 0.4-0.8 turn/minute. This special design makes the bottom of reactor get heated evenly, which can improve the pyrolysis efficiency.

(4)Safe: our plants are equipped with mature safety devices, such as alarm for over temperature and pressure, auto pressure releasing system, extra gas recycling system and fire fighting device, which will guarantee safety in production.

(5)Energy saving: by the extra gas recycling system, the gas generated in the pyrolysis process can be reused, which will save energy.

(6)Environment friendly: in the dedusting system, three steps are used to dedust the extra gas. More than 95% of the dust would be removed. The released gas is pollution-free and can be discharged into the air directly.

(7)Longer service life: the technology of avoiding the reactor of being burnt through by reforming the furnace, which will lengthen the life span of the main reactor for 2 to 3 years. The service life of our plant can reach 5-8 years.
