GPAE 2025 Conference in The Hague, The Netherlands

** Register before 31^st March, to take advantage of the Early-Bird discount **

The GPAE Annual Conference will be held Wednesday 4th to Friday 6th June 2025 at The Hague Marriott Hotel, The Hague, The Netherlands.

One of the strengths of GPAE is the large number of people who have been active members of our organisation and the industry for many years – several of whom will be presenting.

Our conference kicks off on Wednesday 4th June with an afternoon Workshop with the theme of “Purification of Gas for Cryogenic Processes”. The Technical Conference starts on Thursday 5th June, including a Panel discussion on “Roadmap or Roadblock: CO2 and Hydrogen Pipelines" as well as Technical Papers on the following themes from Aramco & MTR, Saipem, Rely Solutions & Technip Energies, Bechtel, KBC, Aramco & Huntsman, Baker Hughes & BASF, TotalEnergies, Worley Comprimo, and SGS Sulphur Experts:

• CO2 Infrastructure
• Green Hydrogen / Green Ammonia
• CO2 Capture
• Traditional Gas Industry

We also have a free dedicated Training Day for our Young Professionals on Wednesday 4th June.

Clean Hydrogen Purification with Catalysts and Adsorbents

This paper was presented at the Presented at GPA Europe Annual Conference 2022, Paris by François-Xavier Chiron, Axens

Regardless of its color (green / blue / pink / white / …), hydrogen will certainly play a major role in the industry energy transition and the future of transportation. While a lot of efforts are naturally put to decrease the CAPEX of clean Hydrogen production, purification is often seen as a black box that still has to deliver up to 99.999 vol % H2. Hydrogen coming out of a manufacturing process (methane reforming / Electrolysis) or stored geologically come together with an array of impurities: oxygen, water, carbon oxides and sulfur to name the major components. Usages in mobility via a fuel cell or the use of hydrogen as a reactant in a catalytic conversion impose tight specification especially on oxygen and water.

This paper focuses on some key purification steps that use catalysts, adsorbents or scavengers to meet the required hydrogen purity.

The first application is the PDU (Purification & Drying Unit) located directly downstream an electrolyser. This purification package includes a deoxo catalyst (Axens commercial name is DO 125) and molecular sieve driers packed in a “zero-loss TSA system”. Depending on the electrolysis technology (AEL / PEM) hydrogen comes out with different levels of oxygen, but always water saturated. Oxygen is easily reacted with hydrogen over a precious metal catalyst: H2 + ½ O2 = H2O. Axens has developed in its historic facility at Salindres, France, a very active Pd based catalyst, supported on a specific alumina. Subsequently, the gas is cooled down and water is knocked out before entering the dehydration section. Based on years of experience in refining and Natural gas treatment, the drying section utilizes Axens MultiBed™ configuration so that water levels as low as 0.1 ppm mol can be guaranteed at the PDU section outlet.

Similarly, a PDU can be installed on blue hydrogen, just downstream the PSA. This unit is very similar to the PDU on electrolysers, with the difference that it is not O2 that has to be removed but traces of CO/CO2. Carbon oxides are well known poisons to fuel cells as well as for catalyst used in the hydrogenation of toluene for LOHC application for instance. Axens proposes MT 201 R, a pre-reduced methanation catalyst that effectively brings the CO/CO2 level to ultra-low concentration. Methanation is classically followed by a zero-loss TSA system, integrated on a skid.

Other purification with Axens adsorbents include the purification of white H2 (native H2) and hydrogen stored in salt caverns where hydrogen comes out enriched in sulfur. Sulfur scavengers produced in Axens factory in Saint-Louis are used to bring the hydrogen back to the highest standard.

Originating from years of experience in Adsorbents and Catalysts manufacturing, Axens proposes purification solution on all kind of hydrogen streams so that any specification can be met.
