Disposal of rocket fuel and land mines in Ukraine
German environmental technology ensures safe disposal of rocket fuel and decommissioned mines in Ukraine.
The Ukraine disposed of its decommissioned intercontinental ballistic missiles of the type SS-24 environmentally friendly. One challenge is the fuel: the multistage missile is driven by a solid substance mixture, which is composed mainly of aluminum (Al), and ammonium perchlorate (NH4ClO4). The disposal of the reactive mixture requires a complicated technique: Improper treatment carries the risk of a deflagration, an uncontrolled combustion with concomitant explosion.
Even if the combustion process is carried out in a controlled, this toxic fumes created with ingredients such as hydrogen chloride (HCl) and nitrogen oxides (NOx), which must be deposited to protect the environment in a flue gas cleaning system reliably.
Combustion at 1 200 degrees Celsius
For the professional, safe and environmentally sound treatment of rocket propellant charges of the Ukraine builds a large disposal complex near the city of Pavlograd. As an internationally recognized environmental technology specialist delivered the Boeblingen plant engineers Eisnemann a six-meter long rotary kiln, which is lined on the inside. This lining ensures lasting and safe operation of the plant at a temperature of 1200 degrees Celsius. In addition to the fuel itself must also glass fiber reinforced epoxy resin sleeves with the SS-24 contain tDisposal of rocket fuelhe solid rocket fuel, to be disposed of in a rotary kiln. The throughput capacity of the furnace of solid rocket fuel is about 850 kilograms per hour.
Multistage flue gas cleaning
That are produced during combustion of the fuel fumes are combusted in a combustion chamber at 1 100 degrees Celsius. This is followed by a nitric oxide-selective non-catalytic reduction process by deposition, called SNCR on. Further stages of the purification process is a quench to the sudden cooling of the flue gases as well as a highly efficient scrubber system including waste water treatment. The tailor-made flue gas purification plant treats up to 3,300 standard cubic meters of flue gas per hour. The resulting clean gas holds both the European limits and the demands of the Ukrainian authorities in safely. The solutions found by Eisenmann designers specifications, there were no model, the plant is the first for this specific use case.
Blast furnace for landmines
The scope of supply for special disposal complex in Pavlograd belonged to Iron Man remains a blast furnace for anti-personnel mines. In it up to 400 pieces per hour, the palm-sized explosive devices are controlled by heat brought to explosion. The construction of the furnace makes it possible to compensate for the resulting pressure wave, and to prevent the uncontrolled splinter flight. The thus generated flue gases are fed to the flue gas cleaning plant of the rocket fuel line. Construction of the two plants was in February 2012, the commissioning began in January 2013.
Iron Man is one of the leading international suppliers of equipment and services in the areas of surface and coating technology, material flow automation, thermal processing and environmental technology. The South German family is represented in Europe, America and the BRIC countries, with 3700 employees and an annual turnover of around 600 million euros (2011).
