INTRODUCTION
PLASTICS
Integral part of our lives
Easily available
Worldwide production 100 million tones / year
Use & throw culture
Universal problem is
waste plastics
PLASTICS
Plastics - important than conventional materials
Properties
Light weight
Durability
Energy efficiency
Faster production rate
Design flexibility
World wide problem – plastic waste management
Landfills – approaching full capacity
Process
Time consuming
Energy consuming
Following two operations are performed in conversion to fuels
They are
DEPOLYMERISATION
FRACTIONAL DISTILLATION
CONVERSION TO FUELS
DEPOLYMERISATION
1. Loading of waste into the reactors
2. Depolymerisation of the waste plastics
3. Collecting the liquid distillate
4. Collecting the combustible gases
QUALITY OF FUELS
The fuels obtained from the process conversion is free from lead sulphur and nitrogen
The fuels prove themselves not only in their regular tests like specific gravity tests but also in the tests like flash point and fire point.
Calorific value also excels
