The main reaction furnace is where the thermal stage of the modified Claus process takes place. In this thermal stage the majority of the sulphur recovered in the sulphur recovery unit is formed. Also impurities such as ammonia and aromatic hydrocarbons are destroyed here. The burner, naturally plays a crucial role in this through the degree of mixing achieved in the furnace as well as the temperature homogeneity that is reached. Furthermore, the flame stability generated by the burner plays a key role in the turndown that can reliably be met and the ability of the sulphur recovery unit to deal with upset conditions upstream.

A History of Innovation

Stricter emission regulations and increasingly sour crudes mean that our industry must constantly innovate. One example of this is oxygen enrichment, spearheaded by Duiker in the world’s first commercially operated oxygen enriched burners, which are still operating widely today. Continuous design improvements have pushed burner efficiency even further. Lean or rich feeds, impurities, two or two and a half thousand tonnes a day, our main burners will provide optimal results.

The Bottom Line

The results on the bottom line are clear too: better destruction of impurities, a higher sulphur yield in the thermal stage, a shift from CS2 formation to COS and the best performance in turn down conditions. This translates in: lower operational expenditures, longer runs of the catalyst beds and a drastic decline in unscheduled maintenance time.
