The oxidative degradation of amines can be connected to the presence and concentration of NO2 in the flue gas, as it results in reactive species. A strategy for NO2 removal based on thiosulfate dosing in the aqueous NaOH solution used in a standard SO2 pre-scrubber has been developed by The University of Texas at Austin up to pilot scale (TRL5) at National Carbon Capture Center (NCCC). In LAUNCH, a number of degradation control technologies will be demonstrated at pilot scale at RWE (WP5), including thiosulfate dosing. For that, the design of the thiosulphate dosing system for the RWE pilot must be established. This design is discussed in the present document.
WP2 - Controlling Degradation
The main objective of WP2 is to develop strategies to control solvent degradation. A number of degradation countermeasures will be designed and tested at the LAUNCH rigs. These will involve modifying the design and operation of capture plants, as well as strategies for removing the components that lead to (or accelerate) degradation. The removal of degradation products themselves, to avoid accumulation, will be included in the degradation control strategy.
Task 2.1 Oxygen removal
Task 2.2 NO2 removal
Task 2.3 Determining the role of iron and technologies for in-situ iron removal

Coordinator Job Role: Scientific Researcher, TNO
Juliana Monteiro has a PhD in Chemical Engineering and holds a position as scientific researcher at TNO in the field of gas treating, in particular CCUS. Since 2009 she has been involved in CCS projects, more particularly in chemical absorption of CO2. Her activities include solvent development and characterisation, modelling and simulation of CO2 capture systems, designing of CO2 capture plants and economical assessment of processes. More recently, she has been involved in developing and evaluating CO2 utilisation technologies, through her involvement in the CEMCAP and CyclicCO2R projects.

More About the Project
Objectives
The primary objective of the LAUNCH project is to accelerate the implementation of CO2 capture across the energy and industry sectors by developing novel solvents and establishing a fast-track, cost-effective de-risking mechanism to predict and control degradation of capture solvents.
Outcomes
The LAUNCH project will deliver the necessary knowledge and tools to allow CO2 capture plants to operate in a more controlled and cost-efficient way. The project will also provide solvent developers with the tools to assist in designing and validating novel solvents. By avoiding uncontrolled build-up of degradation products, LAUNCH will improve the performance and economics of CO2 capture.
