Empowering green ammonia
and energy solutions

Ammonia production

Proton Ventures performed a Front-End Engineering & Design (FEED) study for a renewable ammonia plant in close collaboration with Casale S.A. from Switzerland. This is the smallest ammonia module (NFuel System) in Proton Ventures’ product portfolio.

Proton Ventures developed a conceptual design for a new 300 MTD modular ammonia plant including a class 3 AACE engineering cost estimate. The Ammonia Plant offers maximum flexibility, allowing for future implementation of electrolysers in order to produce green ammonia.


Proton ventures developed a brownfield Basic Engineering (BEP+) design for an ammonia production facility producing 48 MTD of ammonia per year. Hydrogen obtained through a chloro alkaline process, nitrogen and utility streams would be provided by the client (a utility provider) for the production of ammonia.

Liquefied storage & handling

Proton Ventures handled the basic engineering (process, mechanical, electrical, instrumentation & control, piping) for the largest ammonia storage and handling facility in Europe, comprising two refrigerated ammonia tanks (30,000 metric ton capacity, Europe’s largest storage tanks), four UAN tanks (20,000 metric ton capacity), marine loading arm facility, main & holding compressor skid, railroad freight car loading facility & utilities.

In 2013, Proton Ventures performed the basic and detailed engineering (process, mechanical, electrical, instrumentation & control, piping) for the ammonia terminal comprising a 10,000 metric ton storage tank, marine loading arm facility, holding compressor skid, railroad freight car loading facility, scrubber system & utilities

Thanks to this successful collaboration, Proton Ventures was awarded a new project in 2019 to realise a second tank (12,500 ton tank) with associated peripherals. The second tank is already built and the project will be completed before the end of 2022.

DENOX and N2O removal Kavala

In collaboration with Haldor Topsoe, Proton Ventures realised the successful startup of the first TertiNOx™ catalyst reference at Kavala Fertilizers, one of the largest nitric acid producers in Greece. The plant has already exceeded its design conversion with N₂O emissions below 10 ppm and low ammonia slip, and has practically eliminated NOx emissions.

At the current performance level, Kavala Fertilizers’ nitric acid unit in Greece will reduce its greenhouse gas emission by more than 30,000 tonnes of CO2 equivalents per year. This leads not only to more sustainable operation of the plant but also to significant cost savings as a consequence of lower impeded carbon taxes.

Environmental impact study

Ammonia safety study

An important part of the environmental impact studies is the QRA (Quantitative Risk Analysis) which provides among others contour diagrams as shown in the figure. Proton Ventures executed and delivered said studies and cooperates where needed with its partners for this type of work.

Together with its partners, Proton Ventures performed a comparative lifecycle assessment of anhydrous ammonia fertiliser produced from distributed landfill gas. This involved a comparative life cycle assessment (LCA) of small-scale anhydrous ammonia fertiliser produced from distributed landfill gas versus conventional world-scale ammonia production.
