Enhancing effectiveness of fertilizers while keeping energy consumption and emissions 

The world population – and the share of people living in urban environments – is growing fast. The fertilizer industry plays a pivotal role in ensuring that the world's food production keeps pace with population growth.

Ever more challenging requirements on the effectiveness of fertilizers

The growing global demand for food puts enormous pressure on agricultural productivity. There are only two ways to increase yields: Farmers can either use more land for crops or intensify their farming on existing acreage. But land for agricultural use is a limited resource. With existing acreages more heavily farmed, nutrients essential to crop growth are drawn from the soil in ever shorter cycles. Farmers rely on fertilizers to keep the soil healthy. Fertilizers have become the answer to how farmers can utilize their lands more efficiently and more sustainably than ever before.

Fertilizers are the key to enhancing and maintaining long-term productivity on existing agricultural land. But with the pressure to boost yields rising, the market calls for more effective sustainable fertilizers. Industrially produced fertilizers are already playing an important role in the market – and their share is set to grow.

Companies in the fertilizer industry not only have to develop more and more effective fertilizers – they also have to optimize the efficiency of their processes. Fertilizer production is one of the most energy-intensive processes anywhere, and many fertilizer plants have been running for decades. Upgrading legacy machinery is a vital part of the industry’s efforts to combat rising energy costs, reach maximum energy efficiency and meet decarbonization targets. To achieve this – and stay competitive in the fertilizer market – companies rely on powerful and highly-efficient technology.

MAN technology is a leap forward in production efficiency

MAN compressors and steam turbines are used in fertilizer plants around the world to generate ammonia, urea or nitric acid – basic chemicals used in the manufacture of fertilizers.


We provide our customers in the fertilizer industry with full-train solutions, compressors and steam turbines designed to meet the unique compression needs of fertilizer plants. The components of our MAN full-train solutions match perfectly. Built to the same exacting standards, they guarantee efficient and reliable operation with maximum uptime.

NAMAX train for nitric acid processes

The new NAMAX train concept for nitric acid production by MAN Energy Solutions boosts the efficiency potential in nitric acid processes. It brings more power density and a higher rotational speed to the dual-pressure process needed to produce nitric acid. We achieve this by making the AR-MAX1 air compressor and its proven blading technology part of our train concept. The benefit of this breakthrough: Train components can now run at identical speeds – making the intermediate gearbox a thing of the past.

In addition to the AR-MAX1 air compressor, the well-referenced MAN components in the NAMAX machinery train consist of a centrifugal compressor for NOx compression, an MAN steam turbine as well as an MAN axial expander for drive power. All four machines are designed and manufactured to the exacting standards of MAN, ensuring the machinery train can be trimmed for maximum efficiency.

Compared to conventional train solutions, the NAMAX train boosts the efficiency of nitric acid production while cutting both energy consumption and operating costs.

How you benefit:

  • Reduced energy footprint
  • Highest mechanical robustness, increased availability
  • Compact modular train with lower weight
  • Simpler logistics, installation, and commissioning
  • More flexibility in train arrangement
  • No gearbox-related frictional losses and maintenance cost

MAN train solutions for ammonia and urea processes

We offer the full spectrum of turbomachinery trains for ammonia and urea plants from a single source. In ammonia and urea production processes, compressors generate the pressures of the various gaseous media required. In many cases, these compressors are driven by steam turbines. MAN Energy Solutions supplies both individual components and full-train solutions that meet the specific compression needs of ammonia and urea plants.

MAN compressor trains for ammonia and urea processes usually comprise:

  • Natural gas compressor
  • Syngas compressor
  • Air compressor
  • Ammonia compressor
  • Steam turbine drive
  • Carbon dioxide compressor (integrally geared type) for urea production

    How you benefit:

  • Highly cost-efficient
  • Perfectly matched components
  • Reliable operation with maximum uptime
