ISPT Eurydice project almost completed

In the coming months the ISPT Eurydice project will be completed and reported on. The project is a collaboration between AkzoNobel, DOW Benelux, Corbion, Hexion, VITO, ECN (part of TNO) and KWR, under the banner of the Institute for Sustainable Process Technology (ISPT). This means that three years of research is drawing to an end. The research focused firstly on the technical possibilities for the selective recovery of organic components from saline process-water streams; and secondly, on making saline water streams suitable for salt reuse – for chlorine production for instance.

Conceptual design and economic analysis

In the Eurydice project ten case studies from the participating companies were closely examined. Different technologies were selected for the case studies on the basis of economic potential and expert knowledge. KWR concentrated on a wash process, AOP (Advanced Oxidation Processes) and EFC (Eutectic Freeze Crystallisation). PDEng students from TU Delft then created conceptual designs, which provided the basis for an economic analysis. Lastly, KWR carried out an LCA (Life Cycle Analysis) on the three most promising case studies.

Bigger Botlek Brine Recycle

One of the project’s possible spin-offs is the Bigger Botlek Brine Recycle (BBBR). The BBBR concept is based on a centralised treatment of saline wastewater streams (brine) originating from a number of different companies. The brine streams are made suitable for processing in a chlorine-alkali plant. This could lead to the closing of the local chloride/chlorine loop.
