Catalytic Emission Control for Phthalic Anhydride (PA) Plants

An important contribution to protecting the environment – catalytic off gas treatment for Phthalic Anhydride production.

As the base component for production of dyes, insecticides, plasticizer and pharmaceuticals phthalic anhydrate (PA) is increasingly used as intermediate in the chemical industry.

The process of manufactoring PA involves the highly exothermic selective oxidation of O-Xylene in tubular reactors utilizing Süd-Chemie's high performance catalysts PhthalIMAX®.

Specifically for large scale production plants today catalytic incineration is widely used to treat volatile organic compounds (VOC) in the process off-gas to address environmental legislation imposed on PA producers.

Tailor made catalytic solutions out of the EnviCat® VOC catalyst portfolio ensure total oxidation of volatile organic compounds (VOC). EnviCat® VOC catalysts are individually designed utilizing spherical shapes, ceramic or stainless steel honeycombs to achieving optimum performance for each PA plant.

Süd-Chemie's EnviCat® VOC catalyst portfolio offers significant opportunity for PA producers to dramatically reduce VOC emissions by

Superior mechanical properties

Low oxidation temperature (< 250° C)

Wide range of operating temperatures

Low operational pressure drop

High thermal durability

Low catalyst volumes required

Long operational lifetime (> 5 years)

PA off-gas oxidation catalysts are individually designed for optimum operational performance and suitable for new plant designs and unit revamps.

State of the art research and development at Süd-Chemie's technology centers ensures timely evolution of today's catalyst portfolio.

Product Range:

EnviCat® VOC: Platinum/palladium on

metal or cordierite honeycombs

alumina spheres

Service:

Süd-Chemie's service ranges from design or optimization of EnviCat® VOC catalytic converters to catalyst replacement or regeneration already installed off-gas treatment catalyst in close co-operation with PA producers and engineering companies.
