New Paths In Adsorption Technology

Regenerative thermal oxidation is still proving to be the most successful VOC abatement method thanks to its versatility and robustness but catalytic and adsorptive gas purification are both becoming increasingly important, especially for large air flows at low VOC concentrations. Innovative developments result in a significant improvement of the cleaning performance and in the reduction of the total cost of ownership using adsorption techniques.

Thimblefuls of nanowaste – Where Do You Deposit Your Nanorubbish?

Nowadays, nanotechnological materials are present in almost every product we use in our daily lives. The public, however, is barely aware of the potential dangers associated with these materials. Despite toxicological examinations of these products still being in their early stages, this article aims to point out the toxicity and impact of nanotechnological products by highlighting the most important questions for discussion in this context.

An RTO low in pressure fluctuation

Pressure fluctuations at the raw gas inlet of REGENERATIVE THERMAL OXIDATION systems are a well-known issue in VOC removal technology. They can best be described as a type of fingerprint of a regenerative gas cleaning system operating as a VOC oxidizer. The innovative low pressure fluctuation system, however, makes distinctive pressure peaks in RTO operations disappear.

Progress In Corona Discharge for ESPS

In the past, electrostatic precipitation (ESP) was a powerful tool in industrial dedusting. Improved fibre quality and cloth design has led to dry dedusting using ESP being replaced with baghouse filters in many industrial applications. The limited operational accuracy of ESP, ozone formation through corona discharge and stringent emission limits were the main reasons for ESP’s decreasing role. The redesign of discharge electrodes, causing an increased corona current, may contribute to re-establishing ESP in wet off-gas purification.
