Removal of Polycyclic Aromatic Hydrocarbons (PAH) in Green Automotive Tires Production

Removal of polycyclic aromatic hydrocarbons in green automotive tires production

Extender oil is used in the production of green automotive tires, synthetic rubbers, and rubber products as such that improves mechanical properties.

Extender oils have high levels of polycyclic aromatic hydrocarbons (PAHs) which have a carcinogenic effect on human health. Therefore, green automotive tire production uses carcinogens treatment technology aimed at producing environmentally safer tires.

The feedstock containing residual aromatic extract (RAE) and distillate aromatic extract (DAE) is refined and potentially dangerous carcinogens are removed in an extraction column through selective solvent treatment with 
dimethylsulfoxide (DMSO). As a result, PAHs are separated from the oil and and discharged. 

Vaisala Polaris™ process refractometer provides real-time indication of the aromatic content of the oil stream, which strongly correlates with PAH concentration.
