Exhaust air purification by concentration in the fluidized bed adsorber

XPURIS FBP 
FLUIDIZED BED PURIFIER 
 

The FBP system cleans the exhaust air by a combination of adsorption on the fluidized bed of special activated carbon and catalytic oxidation.

HOW DOES THE FBP PROCESS WORK?

The FBP process is a well-established, highly efficient method for concentrating and cleaning large exhaust gas flows. It offers very high efficiency and therefore comparatively low energy consumption. The process is particularly suitable for applications with high volume flows and low VOC concentrations and consists of three main steps.

ADSORPTION

The contaminated air flows over a fluidized bed of special activated carbon, which absorbs the pollutants at relatively low temperatures. This purifies the main air flow directly.

DESORPTION

The activated carbon is cleaned in a separate station with hot fresh air, which absorbs the pollutants. This highly contaminated air then flows into the downstream ACP cleaning system.

OXIDATION

The concentrated exhaust gas is completely purified in the catalytic ACP oxidation process. The heat energy generated is recovered and the purified exhaust air is fed back into the clean main air flow.

TAILORED TO YOUR NEEDS 

Every xpuris FBP system is equipped with a high-quality, special activated carbon bed and catalytic converter adapted to individual customer demands. These ensure compliance with the necessary regulatory requirements.

EXHAUST AIR PURIFICATION 
BY CONCENTRATION IN THE FLUIDIZED BED ADSORBER

Das FBP-Verfahren ist eine effiziente Methode zur Aufkonzentration und anschließenden Reinigung von großen Abgasströmen. Das Verfahren besteht aus den drei wesentlichen Schritten
Adsorption, Desorption und Oxidation: 
1. Adsorption
- Contaminated process exhaust air is initially dedusted and dehumidified
- The exhaust air is then passed over the adsorber fluidized beds using the counterflow principle
- The pollutants are removed from the air and stored in the carbon bed
- The purified, clean air leaves the FBP through the chimney
2. Desorption
 - In the desorber, clean air is heated to the required desorption temperature of 200°
- This air adsorbs the pollutants from the special carbon and thus cleans it back to almost new condition
- To completely clean the activated carbon again, there is a special cycle at significantly higher temperatures
- Depending on the application, this should be repeated regularly on a weekly to monthly basis
- The small, highly contaminated secondary air flow transports the pollutants into the catalytic cleaning system ACP
3. Oxidation
- The hot, VOC-contaminated air enters the ACP oxidation process
- This is where the catalytic oxidation of the pollutants takes place
- In the heat exchanger a large part of the energy used is recovered
- The cooled and clean air flow exits the ACP and is fed back into the main air flow

Die Aktivkohle ist speziell dafür entwickelt, eine Vielzahl von Schadstoffen zu adsorbieren. Das Verfahren ist daher sehr effektiv bei der Reinigung von Abgasen. Da diese Aktivkohle innerhalb des Kreislauf behandelt wird, gibt es nahezu keinen Verbrauch, was sich positiv auf die Betriebskosten auswirkt.
