General
Duiker Clean Technologies develops, designs, delivers and services advanced combustion and process solutions focused on sulfur recovery, ammonia-to-hydrogen and ammonia-to-heat conversion, and emission reduction.
Duiker’s main office is located in Wateringen, The Netherlands, with a branch in Beijing, Peoples Republic China.
Duiker Clean Technologies serves clients in the refining, (petro)chemical, energy, and process industries.
This history of Duiker goes back to 1919 and Duiker Clean Technologies has more than 50 years of experience developing, supplying and servicing industrial (process)combustion and process technologies.
Solutions & Technology
It is a high heat-efficiency process that converts ammonia (NH₃) back into clean hydrogen (H₂), enabling a scalable and affordable hydrogen economy with minimal emissions.
Affordable sustainable energy can only be produced at locations with a huge sun, wind, hydro or geothermal sources. At those locations often the energy consumers are not present. So there is a need for storing & transporting energy. The generated energy will be transformed into green Ammonia because Ammonia is an economic logical choice to store and transport energy. In order to release the hydrogen again, you need ammonia cracking

Ammonia to hydrogen focuses on conversion for hydrogen supply, while ammonia to heat uses ammonia directly as a clean combustion fuel (zero CO2) to generate energy.
Duiker Clean Technologies provides, consulting services and key equipment for Sulfur Recovery Units (SRUs) including high intensity LMV process burners, Main Reaction Furnaces, Mixing chambers, Waste heat Boilers, Stoichiometry-Controlled Oxidation (SCO) systems, and Thermal Oxidizers to ensure emission compliance and high-quality sulfur output.
Firstly Sulfur Solutions are helping our customers to reduce their sulfur emissions to the environment, whilst they produce fuels. Secondly Sulfur Solutions are converting a waste product into a valuable feedstock for fertilers (increased food production.
SCO, or Stoichiometry-Controlled Oxidation, is Duiker’s patented Low NOx ammonia combustion process that fully destruct ammonia waste streams whilst maintaining very low NOx emissions, resulting in less consumption of other fuels and less risks for plugged equipment in SRU’s due to poorly combusted ammonia.
By offering tailor-made technological solutions such as flue gas measurement services, emission monitoring and analysis, and process optimization consulting.
Duiker Clean Technologies systems operate with zero CO₂ emissions in ammonia processes, ultra-low NOx levels, and no wastewater streams—supporting a circular and cleaner economy.
Duiker focusses during their development process on creating the most beneficial solution for its customers, which generate also a meaningful impact on both people and planet. The sulfur and clean energy solutions are great examples of how this spirit of innovation may lead to.
