Oxidative pyrolysis of examination rubber gloves in the integral pyrolysis test plant

Abstract

In order to visualize the practical application of pyrolyzing examination rubber gloves, a new test plant is designed and constructed. This 2 kg/hr test plant incorporates innovative features to ensure sufficient heat transfer to pyrolyze un-shredded gloves. This paper addresses the performance of the plant inclusive of time temperature profile, gas evolution profile and product yield. The performance of this plant is compared against the ideal zero-oxygen pyrolysis rig that was used to pyrolyze 10 grams of cut-up gloves in the bench scale study. It is found that the presence of the oxygen in the plant is inevitable due to imperfect sealing resulting in significant water formation and altering the tail gas and chemical composition of the oil. The main compositions of the oil were found to be esters and phtalic acid.
