SVP-HP® process

 

The newest patented SVP® process is based on use of hydrogen peroxide for reduction of chlorate to chlorine dioxide. The first SVP-HP® plants were started up in 1993. 

NaCIO₃ + ½H₂O₂ + ½H₂SO₄  ClO₂ + ½Na₂ SO₄ + ½O₂ + H₂O
The main advantages for the SVP-HP® process compared with methanol based processes are:

• 30% less salt cake.
• Neutral salt cake, no caustic required.
• No additional equipment required to produce neutral salt cake.
• 25% decrease in H₂SO₄ feed requirements.
• No organic by-products or reducing agents.
• By-product oxygen can be utilized in the bleach plant.

In addition to these new improvements, SVP-HP® chemistry maintains all the advantages of the SVP-LITE® process, including:

• No by-product chlorine.
• No downtime due to boil-outs.
• No "white-outs".
• High reaction efficiency and yield.
• Rapid start-up and shutdown.
