The product is mainly used in the fine desulfurization of natural gas, oil field associated gas, liquefied gas, refinery gas, coke oven gas , water gas, semi-water gas, shift gas and all kinds of waste gas. It has the following features:

1、  High reaction activation: the main composition of PDS₆ is not only sulfonated cobalt phthalocyanine, but catalyst and accelerant. So its desulfurization activation is much 2 times higher than ordinary desulfurizer. Moreover, it has a high reaction speed and less using quantity, which is just the half of PDS.

2、  High desulfurization precision: the industrial experiment shows that after desulfurization, the H₂S content of oil field gas with 3000ppmis decreasing to below 0.1ppm.

3、  Little side reaction: the industrial experiment shows that after desulfurizing by PDS₆, Na₂S₂O₃ content is able to largely decreased, just 10～30mg/L.

4、  Good for sulfur recovery: the industrial experiment shows that, after using PDS₆, the sulfur foam is better, the sulfur crystal size is larger, and the suspended sulfur is less than before. Thus, the desulfurizer viscosity is lower, the solution is clear and the desulfurization efficiency is better.

5、  After using this product, the using quantity of pure alkali is become less than before, and the labor strength lighter.
