The fluidized bed granulator is
the centerpiece of the production
plant. It is where the liquid
ammonium sulfate is turned into
a solid product.

Know-how
that breeds success
thyssenkrupp Industrial Solutions has
decades of experience in supplying
single-source, turnkey solutions to the
fertilizer industry.
There are a number of challenges facing fertilizer producers in
today's world: Stringent environmental regulations are as much
a priority as the demand for increased capacities. Very often
it is aging plants that need to be modernized or even completely
replaced. Many companies also decide to build new multi-complex plants in which different fertilizer products can be produced.
thyssenkrupp Industrial Solutions is a competent partner in
accomplishing all these tasks, supporting customers throughout
the world with comprehensive concepts, ground-breaking engineering and reliable services. Moreover, we implement solutions
in cooperation with equally experienced and competent partners.
This means that our customers benefit from tailored project management with a central contact point.
For existing plants, we offer extensive services to cover the entire
life cycle of the plant. Therefore, plants are always optimally
serviced and maintained so as to ensure optimum productivity at
all times.

From an industrial
by-product to a
high-quality fertilizer
Plant growth depends on the nutrient content of the soil. A balanced distribution of primary and secondary nutrients as well as microorganisms ensures an optimum crop yield.
Nitrogen is an essential nutrient, and so is sulfur.

In today’s world a cleaner environment, tail gas desulfurization
and less acid rain now mean that especially soils that are neutral
or alkaline require the controlled addition of a fertilizer additive
which contains sulfur: ammonium sulfate.

Ammonium sulfate feeds sulfur and nitrogen to the soil. With its
colloidal components, the fertilizer binds to clay particles in the
soil, ensuring a long-term supply of nutrients. Ammonium sulfate
is thus perfect for plants with a long growth period and in areas
with high rainfall. In addition to acting as a long-term plant nutrient, the sulfur also promotes the transfer of micronutrients, such
as manganese, iron and boron, from the soil to the plants.
Input
high-quality
Ammonium sulfate solutions are a pertinent industrial by-product. In addition to sulfate, nitrogen and sulfur are key components of this fertilizer, which is mostly marketed in the form of
crystals. In its state-of-the-art plants, thyssenkrupp has developed a process to convert ammonium sulfate solution to granules. The key advantages compared with liquid and crystalline
solutions: improved storage as well as spreading and mixing
properties.
Alternative granulating plants are not able to process ammonium
sulfate solutions. These plants require expensive ammonia and
sulfuric acid to achieve higher-priced premium product characteristics.

Premium fertilizer for
optimum plant growth
Granulated ammonium sulfate is a high-quality fertilizer which, compared with
standard products, is traded in crystalline form at premium prices. Why choose the
thyssenkrupp Uhde® ammonium sulfate process? The granular form as a unique
selling point and the high profit margin are two very good reasons.
Another advantage: Due to the large quantities produced, crystalline ammonium sulfate is a mass-market product while
granulated ammonium sulfate is produced by only a few suppliers in relatively small quantities. Demand is accordingly high –
and there are sales opportunities in niche markets, too.
