Removal of tag
77.167.0.34 keeps reverting my addition of the tag. The article reads like a promotion for the product. In light of WP:3RR, I should not add it again. Could some other editors review the article and tag it, only if appropriate? Thanks, — Josh3580 talk/hist 19:57, 22 December 2013 (UTC)

Introduction
Stamicarbon was established on May 6, 1947, by DSM (previously Dutch State Mines) to obtain and exploit coal-washing inventions, patents, and know-how. The company’s name reflects its origin: “Stami” (from “State Mines”) and “carbon” (coal). Throughout the years, Stamicarbon’s portfolio grew to include other technologies, including urea, melamine, caprolactam, polyethylene, phenol and EPDM rubber.

In October 2009, Stamicarbon was acquired by Maire Tecnimont Group, an international industrial leader in the transformation of natural resources (plant engineering in downstream oil & gas, with technological and execution expertise). Stamicarbon became the innovation and license company of the Group.

Early activities
Stamicarbon started its activities with innovations in coal washing technologies, which it licensed worldwide until 1989. The company licensed 185 float-and-sink washers, 685 cyclone washers and more than 5000 sieve bends for coal size classification. After the Second World War, fertilizers became important for food production. The produced coke oven gas (a by-product of pit coal) was used to form ammonia, a raw material for nitrogen-based fertilizers. From 1952, Stamicarbon licensed nitric acid and other fertilizer technologies, including urea and mixed fertilizers such as ammonium nitrate, calcium nitrate, ammonium phosphate, single and triple superphosphates, nitrogen phosphate and ammonium sulfate. In 1988, Stamicarbon sold its fertilizer business, excluding urea, to Deutsche Engineering in Germany.

The move to urea
Urea, or carbamide, is a chemical compound produced by reacting ammonia and carbon dioxide at elevated temperatures and pressure. Aside from its many industrial uses, more than 90% of urea produced is used in the fertilizer industry2.

Stamicarbon began researching urea technology in the 1950s. The development of the conventional urea process became possible in 1954 with the introduction of the oxygen patent to suppress corrosion in the urea process. Stamicarbon licensed the first conventional urea plant in 1957 to Société Carbochimique in Belgium, with a capacity of 70 mtpd.

In the 1960s, Stamicarbon invented its CO2 stripping process, a breakthrough technology that made it the world market leader in urea. The process decreased energy consumption by half and became the standard urea process for all Stamicarbon plants since then.

The company continued to innovate in urea, developing pool condenser and pool reactor technologies in the 1990s. Both are characterized by process improvements, smaller plant height and lower investment costs. Mega Design for large plant capacities and Compact Design with an even lower plant height of 22 m were developed in the 2000s.

Stamicarbon’s latest urea technology, Ultra-Low Energy Design, was developed to reduce energy (steam) consumption by using high-pressure steam supplied to the plant three times instead of two. The first plants based on this technology went into operation in China in 2021.

Material innovations
Corrosion in urea synthesis has always been a major problem and Stamicarbon was involved in developing better materials to resist corrosion from the early 1960s. This first led to the development of austenitic 316L urea grade steel and later the X2Cr.Ni.Mo.N 25.22.2 steel with a high chromium and nickel content. The breakthrough came in 1996 when Stamicarbon and steel manufacturer Sandvik developed Safurex® duplex (austenitic-ferritic) stainless steel for high-pressure equipment, valves and piping for urea synthesis. Safurex® became the standard construction material in new urea plants and is regularly used in replacing old high-pressure vessels.

Emission reduction
Stamicarbon and EnviroCare International co-developed a high-efficiency off-gas scrubbing technology and integrated it with Stamicarbon’s fluidized bed urea granulation technology. By quenching and accelerating the granulation off-gas through MicroMist™ Venturi (MMV) tubes, particulate emissions below 10 mg/Nm3 can be achieved.

Increasingly strict environmental regulations for prilling towers stimulated both companies to develop the Jet Venturi (JV) Scrubber to remove submicron urea dust particles from prilling at high efficiencies. The JV Scrubber is suitable for both natural and forced draft prilling towers and can be placed at ground level or on top of the prilling tower. Pilot prilling tower test results have reduced dust emissions to <15 mg/Nm3.

Future-oriented technologies
Specialty fertilizers Stamicarbon developed Controlled-Release Fertilizer Design in partnership with Pursell Agri-Tech. This smart fertilizer has a polymer coating that contains the nutrients inside the membrane and prevents valuable nutrients from leaching into the soil and volatilizing into the air, leading to effective nutrient uptake.

Green ammonia With the launch of the Stami Green Ammonia technology in 2021, Stamicarbon became an ammonia licensor for small-scale ammonia plants. This technology allows to produce ammonia from renewable energy sources, offering a solution for the sustainable production of nitrogen-based fertilizers3.

Digitalization Stamicarbon developed a new suite of digital services to help producers train employees, improve plant effectiveness and boost productivity. This suite includes Operator Training Simulator, Process Monitor, Plant Optimizer and other digital services.

Urea Symposium
Once every four years, Stamicarbon holds its Urea Symposium, at which new technological developments are introduced and social contacts are established or refreshed4. The first Symposium took place in 1966 and was attended by 31 participants representing 16 licensees from 11 countries. Since then, the audience was expanded to include contractors and equipment suppliers. Stamicarbon’s latest Symposium was held in 2022 in Utrecht, the Netherlands, bringing together more than 250 attendees from various parts of the world.
