Abstract:
Waste plastic is a problem that bluster the environment so it has to be solved. Science introduces rotary kiln reactor technology to process waste plastics using gasification process to produce valuable industry synthesis gases mainly carbon monoxide and hydrogen. In this study concentration was made on avoiding red hot spots RHS that occur in rotary kiln reactor RKR during decomposition of plastic at high temperature to produce synthesis gases (CO, H۲). Focus is made on impact of sensitivity analysis variables on process thermodynamics and gas products amount. On other hand PVC affection on gasification is studied. Different feed stocks are used in this study including PVC, Polyethylene, Polypropylene, Polystyrene and Acrylic. The effect of many parameters is tested including feed moisture, flame temperature, insulation thickness and the speed of rotation of RKR. More pvc in the feed leads to less synthesis gases conversion in the products as of that more heat is needed so red hot spots will occurred and more poisons chlorine gas emission that must be processed. Flame temperature must be balanced to give the best conversion and doesn't cause red hot spots as known increasing the flame temperature leads to more waste plastic conversion to synthesis gases on the other hand cause RKR outer surface temperature increasing also radiant heat transfer coefficient increasing that leads to heat loss increasing.
