Colleagues at the Deggendorf site lead the world when it comes to building highly complex reactor systems.

Reactors for the chemical industry, for producing synthetic fuels and even for fusion energy – the specialists for these technologies, be it in development or production, can be found at the Deggendorf site. In summer 2023, colleagues at the site were able to celebrate a landmark when the 800th reactor left production and embarked on its journey to a chemical customer in the USA. In Mobile, Alabama, Evonik Industries is going to produce methyl mercaptan using technology from Deggendorf. This chemical is employed in the manufacture of, among other things, the amino acid L-methionine, a key component in animal feed production. Owing to the process gases used, the reactor had to be in a highly corrosion-proof and gastight design. The materials, not to mention operating temperatures of up to 400 °C, demand many years of experience in the requisite welding techniques. It is precisely in such extremely sophisticated welding work that MAN ES’s Deggendorf employees lead the world.

Methanol synthesis in Chile

But reactors built in Deggendorf are used in much more spectacular projects. Among other things, MAN Deggendorf supplied the methanol synthesis reactor for the ‘Haru Oni’ e-fuel demonstration plant near the city of Punta Arenas in Southern Chile, which produces climate-neutral e-gasoline on behalf of Porsche AG. As a first step, the plant is employing wind power to make hydrogen, which is turned into methanol and finally e-gasoline.

Fusion energy in France

Specialists from Deggendorf are also involved in ITER, one of the most complex science and technology projects of all time. In Cadarache in the South of France, future energy generation will one day be revolutionized by means of a fusion reactor. MAN Deggendorf is involved in building the facility’s centerpiece, the cryostat. The scale is vast: when fully assembled, the cryostat will be 30 meters high, weigh 3,850 metric tons and have a volume of 16,000 square meters. It is made up of 54 individual elements, which are being assembled and welded by 40 MAN experts – a process that will take 10 years in total. The work being done by the MAN specialists demands unparalleled accuracy: “We are working with the precision of a clockmaker on components weighing thousands of metric tons,” says MAN Project Manager Andreas Binni. Which is why his people are constantly refining their assembly strategy and welding techniques as time goes by.

Head of Site Norbert Anger is rightly proud of his workforce: “Our employees possess valuable and unique expertise in the process engineering and assembly of highly complex reactor systems. Our customers, who come from a wide variety of industries, have been relying on our outstanding skills for decades.”

The e-fuels revolution at the “End of the World”

Commissioned in December 2022 in the Southern tip of Chile, the Haru Oni demonstration plant could pave the way for a viable alternative to fossil fuels: It produces synthetic e-fuels from hydrogen that can help the fight against climate change. MAN Energy Solutions provided the e-methanol reactor to the plant.

Tomorrow's energy revolution

Thirty five nations; more than one million components assembled in factories around the world; over 20€ billion of investment; one of the most complex scientific and engineering projects ever seen: ITER (‘the way’ in Latin) is a project of superlatives. In southern France, a multinational cast of thousands is building the world’s largest tokamak, a magnetic fusion device that could change the future of sustainable energy production. And MAN is playing a major role.
