Successful start-up of TertiNOx system at site in Greece

Successful start-up of TertiNOx system at site in Greece

Schiedam, The Netherlands / Kongens Lyngby, Denmark 14 January 2021End October 2020 Proton Ventures BV, an engineering company in the Netherlands specialised in ammonia technology, and Haldor Topsoe, global leader in catalysis, technology, and services for the chemical and refining industries, successfully started-up the first TertiNOx system at one of the biggest nitric acid producers in Southern Europe, Kavala Fertilisers LTD, Greece.

Nitric Acid plants are now globally striving to reduce both NOx (acid rain precursor) and N2O (298x CO2 equivalents) emissions.

Proton Ventures as the main engineering contractor, conducted the Basic (along with Haldor Topsoe) and Detailed Engineering Project for the deNOx and N2O reduction emissions in the major Nitric Acid production plant in Greece. Proton Ventures is procuring this combined NOx & N2O tertiary Topsoe catalyst (TertiNOx™) which is highly active for NOx removal and will ensure compliance with any NOx regulations while eliminating also N2O. The unique cooperation between Haldor Topsoe and Proton Ventures places the client as best in class concerning environmental emission from the nitric acid plant.

Apart from the environmental benefits, reducing N2O emissions from nitric acid units is a cost-effective way to reduce greenhouse gas (GHG) emissions and therefore save on CO2 tax credits. The new Selective Catalytic Reduction (SCR) system managed to reach 99% conversion for both NOx and N2O while ensuring safe operations of the plant with a low slip of ammonia (<5ppm).

‘With the new deNOx&N2O removal system, we are very proud to be able to outperform the current Best Available Technologies achieving extremely low emission levels‘, states Dr. Theodora Kouloura, Chief Operations Officer at Kavala Fertilisers LTD.

“The specific project has been of major importance for the plant and local community as it eliminated toxic emissions (NOx) present as a yellow plume for more than three decades. Additionally one N2O molecule counts for 300 CO2 molecules as a greenhouse gas equivalent. Therefor the environmental footprint of the unit has been dramatically reduced by 36.000 tonne CO2 equivalents. Seeing the people in the control room clapping has been a thrilling moment that justified all our efforts to retrofit this catalytic reactor,” according to George Dodoros, SCR Product Manager at Proton Ventures.

“We are thrilled to see the excellent performance and positive climate effect of Topsoe’s TertiNOx™ technology in its first application world-wide. Globally, it is very important to reduce emissions of the extremely potent greenhouse gas N2O as well as NOx, and this project has shown that TertiNOx™ does that in a very cost-effective and efficient way. We are extremely proud to fight climate change together with Proton Ventures and the customer,” says Janus Münster-Swendsen, Business Development Manager at Haldor Topsoe.

Proton Ventures wins SABIC Challenge and investigates the possibility of a green ammonia production plant

Schiedam November 17, 2020 – On October 2, Proton Ventures received an innovation contract from BioVoice Innovation & Business Booster for the SABIC Hydrogen Challenge. This innovation contract with a pilot assignment gives Proton the opportunity to conduct a feasibility study. It is being investigated whether it is technically and economically feasible to build a green ammonia plant with the aim of locally producing 8,500 tons of green ammonia per year at SABIC’s production location, Bergen op Zoom.

SABIC Bergen op Zoom produces hydrogen as a by-product of chlorine production without releasing CO2. This hydrogen is formed from water by electrolysis and can therefore be considered green. Currently, the hydrogen produced is incinerated, after which the heat is (largely) reused in processes. SABIC is looking for a more sustainable solution for the use of hydrogen and has issued a challenge for this. Hydrogen is an important raw material for ammonia (NH3). In addition to a fertilizer, ammonia is also an energy carrier, NFuel.

“Ammonia is not only a fertilizer raw material, but also a good energy carrier. After years of discussion about the use of ammonia as an energy carrier, there is an increasing tendency to use ammonia in various fuel applications, such as marine fuel and fuel for the automotive industry. The technology of Proton is seen by SABIC as a possible solution to their energy challenge, where we expect this technology to be able to use their surplus hydrogen at an attractive market value and at the lowest cost. Proton wants to realize an 8,500 tonne NFuel plant on site of SABIC, where the sale of ammonia can ultimately be sold to the fertilizer and/or energy sector”, says Hans Vrijenhoef, CEO Proton Ventures BV.

Vrijenhoef indicates that the energy content of 8,500 tons of NFuel corresponds to 80 GWh of energy content of which approximately 30% could ultimately satisfy the power usage of approximately 7,500 households.

During construction and commissioning of the NFuel plant, part of it is also returned as green ammonia to an existing fertilizer producer in the initial phase. This ammonia is produced without the CO2-emitting steam methane reforming (SMR) technology that is responsible for many CO2 emissions worldwide. Therefore, no natural gas is used in this process.

Proton leads in new ISO LNG railcar standard

Schiedam, the Netherlands, 13 October 2020 – Proton Ventures is leading the working group for a new ISO LNG railcar applications standard to fill the gap in best design and safety related practices for existing and new LNG terminals. 13 committee members from different countries including Australia, Japan, China, France, Germany, Poland, the Netherlands and Spain work together in standardizing latest developments and best design choices drawing from experience on their terminals or design projects. Participating companies include ENGIE, JAPEX, Shell, Gate Terminal, Polskie LNG, CNOOC China and Enagas Spain.

Proton Ventures plays an important role in setting the standard as the convener of the working group chaired by George Dodoros, Project Manager in previous railcar LNG projects. ‘It is exciting that all participating companies agreed that this is the right time to make a new LNG railcar application standard laying the ground for the future designer or plant manager. The LNG market is expanding rapidly, market volatility independence and strategic reserves are growingly more important, therefor LNG railcar transportation momentum is arriving,’ according to Dodoros.

Proton Ventures is keen on undertaking more LNG related challenges and committed to stay on the edge of technology when it comes to state of the art designs with maximum safety and operability.
