SDT-DS109 Special Room temperature desulfurizer for carbon dioxide
1. Uses and characteristics
SDT-DS109 Carbon dioxide-specific ambient temperature desulfurizer is a strip-shaped desulfurizer developed based on the characteristics of carbon dioxide-containing gases and the presence of a large amount of water vapor. It is made from iron salts as the basic raw material, chemically synthesized into special active iron oxide, and processed into shape with the addition of composite additives and binders. This product features high content of active substances, good selectivity, high desulfurization accuracy, well-developed pores, low usage resistance and is not prone to caking. It is used for the removal of hydrogen sulfide, carbonyl sulfide and small molecule mercaptans in carbon dioxide gas.
Principle of desulfurization:
FeO(OH)＋2H2S 
FeSSH +2H2O

3.Packaging, storage and transportation
1. The desulfurizer is packed in tons of bags or woven bags, lined with plastic bags.
2. Rolling, collision and violent , vibration should be avoided during transportation to avoid crushing.
3. Under the condition of not damaging the packaging, it can be used normally after 1~2 years of storage.
