SDT-DS102 Series oilfield associated gas desulfurizer at room temperature
1. Uses and characteristics
SDT-DS102 high-efficiency desulfurizer for oilfield gas at room temperature is a strip desulfurizer developed with iron salt as the basic raw material, converted into special activated iron oxide by chemical synthesis, and processed by adding composite additives and binders in the process of crude oil exploitation. The product has the characteristics of high active substance content, large sulfur capacity, low use resistance, high hydrogen sulfide purification, good oil resistance, and adaptation to high carbon dioxide, and is used for the removal of hydrogen sulfide and small molecule mercaptan in the associated gas in the oil exploitation 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.
