Project Description

Sulfur recovery catalyst is applied to the Sulfur Recovery Units, also known as Claus Units, use sour gas or acid gases as feed from sweetening units and sour-water strippers. The feedstock is sent into a proprietary burner system and the mixture of hydrogen sulfide and sulfur dioxide reacts to form elemental sulfur which we call it Claus reaction.There are many sulfur recovery technologies available for different applications, however the most common conversion method used is the Claus process. Approximately 90 percent of the sulfur from the processing natural gas and refining high sulfur crude oils is recovered by the Claus process.

The reaction consists in two steps:

2 H2S +3 O2 → 2 SO2 + 2 H2O
2 H2S +SO2 → 3/2 S2 + 2 H2O

However, the Claus process typically recovers maximum 98 percent of the hydrogen sulfide feedstream. If necessary, a Tail Gas Treatment Unit (TGTU) is required to recover the remaining sulfur components, the customers can choose tail gas treatment options to further increase sulfur recovery. After tail gas treatment by CoMo catalyst,the Claus tail gas is catalytically purified, resulting in an overall sulfur recovery rate of up to 99.5% or higher.
