Therefore the need for hydrogen is experiencing a very rapid growth. At the same time, the traditional hydrogen production methods (e.g., steam methane reforming, water electrolysis) are energy and resources intensive. Thus, research focus is on sustainable technologies that can produce hydrogen in an economic and environmental friendly way. Hydrogen production via a solar driven hybrid sulfur-ammonia water splitting cycle (HySA) developed at Florida Solar Energy Center is such a promising technology. -

Membrane Separation of Ammonium Bisulfate from Ammonium Sulfate in Aqueous Solutions for CO2 Mineralisation
Article Membrane Separation of Ammonium Bisulfate from Ammonium Sulfate in Aqueous Solutions for CO2 Mineralisation Evelina Koivisto and Ron Zevenhoven * Thermal and Flow Engineering Laboratory, Åbo Akademi University, Piispankatu 8, 20500 Turku, Finland; [email protected] * Correspondence: [email protected]; Tel.: +358-2-215-3223 Received: 24 February 2018; Accepted: 2 April 2018; Published: 4 April 2018 Abstract: The separation of ammonium bisulfate (ABS) from ammonium sulfate (AS) in aqueous solutions by monovalent ion selective membranes was studied. Optimised usage of these chemicals is both an important and challenging step towards a more efficient CO2 mineralisation process route developed at Åbo Akademi University (ÅA). The membranes were placed in a three or five- compartment electrodialysis stack. Silver, stainless steel and platinum electrodes were tested, of which a combination of Pt (anode) and stainless steel (cathode) electrodes were found to be most suitable. Separation efficiencies close to 100% were reached based on ABS concentrations in the feed solution. The tests were performed with an initial voltage of either 10 V–20 V, but limitations in the electrical power supply equipment eventually resulted in a voltage drop as separation proceeded. Exergy calculations for energy efficiency assessment show that the input exergy (electrical power) is many times higher than the reversible mixing exergy, which indicates that design modifications must be made. Further work will focus on the possibilities to make the separation even more efficient and to develop the analysis methods, besides the use of another anode material. Keywords: ammonium (bi)sulfate; CCS; CO2 mineralisation; electrodialysis; ion selective membranes 1. Introduction CO2 mineralisation is one method to sequester CO2, especially at locations where underground storage is impossible or where the market potential of the solid products is recognised. -
