Ozone Compression in Paper Pulp Bleaching

The process of using ozone as an oxidizing agent to bleach pulp has been developed as an environmentally friendly alternative to the traditional method of using Chlorine. Ozone is desirable for this process because it is an unstable gas that quickly deteriorates into oxygen after the bleaching process, leaving clean pulp that is free of unwanted chemicals. It also reduces pollution to both the air and water supplies.

In this application, our liquid ring compressors are used to compress ozone gas in order to mix it with the pulp. Liquid ring compressors offer isothermal compression characteristics that will not cause thermal degradation of the temperature-sensitive ozone gas.
