Comparison of Different ClO₂Processes from a Technical and Economical Point of View

Abstract

Three different ClO₂ processes are compared basicaliy including following parameters:
1. Consumption of raw materials and utilities
2. Production of by-products
3. Product quality
4. Operational characteristics
5. Process features
6. Costs of operation and investment
The selected processes are:
1. SVP-LITE^®/R 8, methanol based process, world-wide the most common process used today.
2. HP-A^TMprocess, peroxide based process, of special interest in Japan because of easy conversion and capacity expansion from existing R 2/Mathieson plants
3. Integrated process, where ClO₂generation is integrated with chlorate electrolysis an hydrochloric acid production
