摘要

Low PAH pitch binder implementation in Alcan's H.S. Soderberg plants marks an important step in the Company's continuing efforts to reduce the Polycyclic Aromatic Hydrocarbons (PAH's) emission of the Soderberg technology. Improvements to H.S. Soderberg anode formulation and implementation of the low PAH pitch binder has provided a significant reduction in PAH's emission in Alcan's H.S. plants over the last twenty years. A demonstration test was carried out with a low PAH pitch in the Soderberg plant before Alcan's H.S. plants conversion to this new generation of pitch. The impact of this new generation of pitch on the paste plant operation, anode performance and PAH's emission during cell operation was evaluated. The plant performance of the low PAH pitch in terms of emission was compared with the laboratory characterization of the pitch.
