With January 1st, 2020 marine ships are subject to stricter sulfur dioxide emission legislation. To reach the emission reduction goals, packed absorption columns are frequently employed for flue-gas treatment on board the ship. However, currently available column packings do not properly match the key demands for this application. The HiPaSEED project aims to provide a new packing specifically tailored towards flue-gas desulfurization on marine ships.
In the wake of preliminary studies, an existing pilot plant for the characterization of column packing hydraulics was made fit for mass-transfer measurements. Hydraulic characterization of the column packing Raschig RSP 250Y was performed and results are in good agreement with literature data. Furthermore, first mass transfer measurements using a CO2-NaOH test system were performed. It is indicated that the number of transfer units decreases with increasing gas load. In the future, these findings will be used to derive a new geometric structure for a high-performance packing for an application in flue-gas desulfurization on marine ships.
