· Polystyrene (PS) Production and Manufacturing Process. Polystyrene was first produced commercially in the 1930s and the ready availability of styrene feedstock has helped it to grow. Styrene will polymerise spontaneously on heating in an oxygen-free atmosphere but catalysts are added to ensure complete polymerisation at lower temperatures.
· A pilot plant has been operating since 2002 and commercialisation could be possible by the end of the decade. Exelus, the Livingston, New Jersey, research organisation, has tested in the laboratory a styrene process based on the alkylation of toluene with methanol.

Styrene, also known as phenylethylene, vinylbenzene, styrol, or cinnamene, C6H5–CH=CH2, is an impor-tant industrial unsaturated aromatic monomer. It occurs naturally in small quantities in some plants and foods. In the nineteenth century, styrene was
PLANT DESIGN FOR PRODUCTION OF STYRENE 2016 EXECUTIVE SUMMARY Styrene who is also known as ethylbenzene,vinybenzene and phenylethene is an organic compound with the chemical formula C6H5CH=CH2. Although styrene was discovered way back in 1839, its commercial production and applications were developed in the 1930s.
