Sulphur Recovery Equipment
With refineries facing larger demand on their Sulphur Recovery Capacity and problems with sour water, Duiker introduced their novel SCO-concept
In the late 1950’s the Duiker en Co’s Fabriek van Apparaten en Werktuigen was contracted to build the first Lyunet Multiple Vortex burner. Uniquely this burner was designed specifically for use in a Sulphur Recovery Unit (SRU). This new unit had, after the improving of the Claus process by I.G. Farbenindustrie in 1938, become the predominant method to process the sulphur contained in oil and gas. Looking back we can confidently acknowledge that both the burner technology as well as the modified Claus process have since revolutionized the industry. Proudly we still consider Duiker Combustion Engineers one of the front runners in this industry today.Back to overview

Sulphur Recovery Equipment
consist of

Acid gas fired combustion equipment
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.

Fuel gas fired combustion equipment
When we consider fuel gas fired combustion equipment in the sulphur recovery unit, we can distinguish between the substoichiometric in-line re-heaters and reducing gas generators and the superstoichiometric incinerator.

Stoichiometry-Controlled Oxidation
With refineries facing not only larger demand on their sulphur recovery capacity, but more and more, face capacity problems due to the quantity of sour water they generate, Duiker introduced a novel concept.

Thermal Oxidation Systems
Thermal oxidizers or incinerators are quite unique in the sulphur recovery unit since they are the only piece of combustion equipment that operates with excess air.
