Features Of LAN-XESS Rhenogran Na2CO3-70/CO Desiccant

  1. Highly effective moisture scavenger specifically formulated for CO-rich process streams.

  2. Granular sodium carbonate-based desiccant with controlled particle size distribution for optimal bed stability and pressure drop performance.

  3. Chemically stable under typical syngas and carbon monoxide processing conditions.

  4. Low dust generation during handling and loading, supporting safer operation and reduced filter fouling.

  5. Consistent activity retention over extended service cycles in fixed-bed dehydration applications.

Typical Applications Of LAN-XESS Rhenogran Na2CO3-70/CO Desiccant

  1. Syngas drying prior to Fischer–Tropsch synthesis units.

  2. Moisture removal in carbon monoxide purification trains for chemical synthesis (e.g., acetic anhydride, phosgene).

  3. Pre-treatment of feed gas for low-temperature CO shift reactors.

  4. Dehydration of CO-containing purge streams in methanol and ammonia plants.

  5. Guard bed protection for sensitive catalysts in carbonylation processes.
