Nowadays refineries, gas processing plants and refineries converted for bio fuel facilities for producing (petro)-chemical products out of fossil or bio fuels, need advanced technologies to stay ahead of the more and more stringent regulations. Their license to operate becomes more important these days, not only to cope with stringent emissions requirements but also to account for their impact on local environment and residents. The sulfur solutions that Duiker Clean Technologies can provide, offer proven and reliable solutions for refinery operators to limit their SO2 emissions that causes acid rain with disastrous impact on the environment. The Luynet Multiple Vortices LMV burner principle, applied since 1961 in SRU’s has shown its unparalleled features as the “high intensity burner” and its extremely strong mixing characteristics.
The SRU process, or more specific, the modified Claus process needs, the so called, thermal stage to kick-start the conversion process. The thermal stage comprises of the Main burner, The Main Reaction Furnace and the Waste Heat Boiler. After this thermal stage about 70% of the H2S has been converted into sulfur. So it is pivotal the chemical conversion process in this stage of the process must be flawless and of excellent performance to get the most out of this conversion process. Needless to mention that the average composition of the acid gas stream feeding the main burner does not contain only H2S but often also H2O, CO2, hydro carbons, NH3 , RSH (mercaptans) and sometimes BTEX (aromatics, ethylene) . The combustion process must therefore not only partially oxidize the H2S but also completely oxidizes (destruct) the contaminants in the feed. Not complying to the latter may not only lead to soot, which becomes clearly visible as a gray veil on the fluorescent yellow sulfur, which lead to a less valuable sulfur product, it may also lead to severe corrosion and irreversible plugging and fouling of downstream equipment in case of not properly combusted NH3, causing considerable downtime of your SRU!
With over 60 years of expertise in H2S combustion and decades of industrial process knowledge, Duiker has developed the best performing & scalable combustion technology available in the market.
The Duiker process combustion system is based on three key “T”’s :
Temperature, Time and Turbulence.
Designing a Thermal Stage based upon a optimum of these Three T’s will lead to the lowest TCO. Hence a choice for a Duiker Thermal Stage leads to the highest impact on people and the Planet at the lowest costs.
The thermal stage of the SRU is often called the Heart of the SRU because 70% of the conversion from H2S to Sulfur will be achieved in this section.
The innovative mindset of Duiker has it made possible to invent trustworthy rules for scalability and flexible configurations for the principle of the LMV burner technology.
The LMV burner technology, embedded in a modern SRU, enables refinery operators to lower their SO2 emissions above 99% and thus highly contributes to the environment.
The optimized choices for the famous 3 T’s for combustion, Temperature, Time and Turbulence greatly benefits to the excellent performance of the high intensity combustion process, enabling maximum conversion from H2S into Sulfur.
Simplify your supply chain: Duiker offers the Main Burner, Main Reaction Chamber, and Waste Heat Boiler as a fully integrated package, reducing complexity and interfaces.
