SDT-DS101 Series room temperature desulfurizer for natural gas
1. Uses and characteristics
SDT-DS101 series of high-efficiency desulfurizers for natural gas at room temperature are developed for natural gas storage, transfer stations and single wells, which have the characteristics of large gas volume, high hydrogen sulfide content, high system pressure and unstable gas flow. It is a strip desulfurizer with iron salt as the basic raw material, which is converted into special activated iron oxide through chemical synthesis, and processed by adding composite additives and binders. The product has high active substance content, high sulfur capacity, well-developed pores, and makes With the characteristics of low resistance, high purification degree of hydrogen sulfide, good impact resistance and water resistance, it is used for the removal of hydrogen sulfide and small molecule mercaptan in natural gas with high hydrogen sulfide content and dry desulfurization process.
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.
