Design And Fabrication Of Pyrolysis Unit For Generation Of Fuel From Plastic Waste

Abstract

Liquid fuel i.e. hydrocarbon fuel is obtained from four different types of waste plastics, those are low density polyethylene and high density polyethylene (LDPE and HDPE), polypropylene (PP) and polystyrene (PS) were carried out in a reactor stainless steel system. Each of the plastics has different chemical and physical properties so the experiments were carried out individually for each of them.

LDPE is used for manufacturing of Containers, Dispensing bottles, etc. HDPE used for production of plastic bottles, Corrosion resistant pipes, etc. PP is used for Packaging in Consumer products, etc. PS is used for producing Disposable plastic cutlery and dinnerware, etc.

Simple thermal degradation was used to melt the plastics at temperature ranging from 120 to 400°C. Vapour condensation from the melted plastics produced the liquid hydrocarbon product. Similar standards were followed for each of the plastics during the production process. The effect of reaction on quality and yield of the product were investigated.

The chemical properties of the liquid product had varied from each plastic. Each of the liquid products contained low sulphur but each of them varied from each other. The waste plastics can also be randomly mixed with each other prior to the liquid production process. The results of mixed plastics production process indicates higher yield percentage than when they are done separately
