Project Details


The Zero H2S - DEMO project deals with the H2S scavenging process carried out in offshore oil and gas. The project aims at reducing the environmental impact factor of this process, by reducing the amount of organic chemicals (spent and unspent H2S scavengers) discharged into the sea.
The project aims at demonstrating the feasibility of a membrane-based process for recovering the unspent H2S scavenger (MEA-triazine) and of a hydrothermal oxidation process for cleaning the spent scavenger wastewater.
This demonstration project, funded by the Danish Offshore Technology Centre (DOTC), builds upon the Research Project "Zero Discharge of H2S Scavenging Chemicals", where the innovative technology was proved at laboratory scale, and aims at demonstrating the technology at pilot scale in relevant environment (TRL-6).
