Chlorine dioxide production process of Cellchem

Cellchem is the contracting and engineering division of Eka Chemicals, the largest producer of sodium chlorate in the world. Cellchem has actively been developing and promoting technology within the chlorine dioxide field for many years. Basically all processes of commercial use in the world today are on our product program. In this paper we will focus the attention on the most interesting processes considering the needs of the pulp mills in Japan. The selected processes to be highlighted are SVP-LITE and HP-ATM. SVP-LITE process is very reliable and safe to operate and is the most economic and popular process today. HP-ATM process is especially attractive when converting older atmospheric system to newer technology. Capacity expansions of 1.5-2 times can be achieved utilizing existing reactor systems. We will also briefly present a new developed add-on process to SVP-LITE or SVP-HP. It is called Generator Liquor Split process, SVP-GLS. It basically converts the saltcake by-product into acid and caustic soda.
