Measurement and prediction of oxygen solubility in post-combustion CO2 capture solvents

This work aims to understand oxygen solubility in pure and aqueous amine solvents for CO2 capture. Commercially available dissolved oxygen sensors were studied to evaluate whether these can be used for measuring oxygen solubility in the carbon capture processes. It also aims to understand the possible discrepansies from realistic concentrations...

Impact of dissolved oxygen removal on solvent degradation for post-combustion CO2 capturew

One of the major issues encountered in the Post Combustion CO2 Capture processes is the degradation of the solvent which can be in great part attributed to the presence of oxygen in the solution. The present report focuses on the demonstration of DORA (Dissolved Oxygen Removal Apparatus), a technology developed by TNO as a counter-measure of...

Understanding Solvent Degradation: a study from three different pilot plants within the OCTAVIUS Project: 13th International Conference on Greenhouse Gas Control Technologies, GHGT 2016, 14-18 November 2016, Lausanne, Switzerland

Degradation of amines is one of the most important issues to be addressed for absorption-desorption based post-combustion CO2 capture. Several laboratory studies have been performed to identify the degradation products and understand the mechanisms of degradation. However, there seems to be a gap in knowledge from translating the lab scale...

Membrane-assisted CO2 liquefaction: performance modelling of CO2 capture from flue gas in cement production

CEMCAP is an international R&D project under the Horizon 2020 Programme preparing the ground for the large-scale implementation of CO2 capture in the European cement industry. This paper concerns the performance modeling of membraneassisted CO2 liquefaction as a possible retrofit application for post combustion CO2 capture. For the relatively...

Aerosol measurement technique: Demonstration at CO2 technology centre Mongstad

There are two main routes for amine emission. The first one is connected to volatile amine emission. The second route is amine emission via aerosols. Recently, it has been observed that under certain conditions and at specific test locations significant aerosol formation and emission can occur. To distinguish between the two routes for amine...

OCTAVIUS: A FP7 project demonstrating CO2 capture technologies

The OCTAVIUS project (Optimisation of CO2 Capture Technology Allowing Verification and Implementation at Utility Scale) has started on March 1st 2012 for a period of 5 years, as part of the 7th Framework Programme of the European Commission. Gathering 15 European and 2 South African partners, OCTAVIUS was conceived as contributing to...

OCTAVIUS: Evaluation of flexibility and operability of amine based post combustion CO2 capture at the Brindisi Pilot Plant

Solvent storage is an option for amine based post combustion capture that can be used to de-couple the capture of CO2 and the energy demand of the process. In this process, electricity output of a power station is temporarily increased by diverting steam from the CO2 capture plant back to the steam turbines. To maintain CO2 capture, an increased...

Concentrated aqueous piperazine as CO2 capture solvent: Detailed evaluation of the integration with a power plant

An integrated energetic evaluation has been performed of a reference coal-fired power plant, a power plant with an advanced MEA-based post-combustion CO2 capture plant, and a power plant with a capture plant using concentrated piperazine (PZ) and high-pressure flash regeneration. This comparison shows that using a MEA-based capture plant reduces...

Energetic evaluation of a power plant integrated with a piperazine-based CO2 capture process

Extensive research efforts have been applied to obtain more efficient and less cost-intensive absorption-based processes and solvent systems for CO2capture during the last 15–20 years. High concentratedaqueous solutions of piperazine (PZ) have been suggested as a good replacement for the current bench-mark solvent mono-ethanolamine (MEA). So far...

HiPerCap: A new FP7 project for development and assessment of novel and emerging post-combustion CO2 capture technologies

The HiPerCap (High Performance Capture) project started 1st January 2014 as a part of the 7th framework program of the European Commission. HiPerCap aims to develop novel post-combustion CO2 capture technologies and processes which are environmentally benign and have high potential to lead to breakthroughs in energy consumption and overall cost....

Next generation post-combustion capture: Combined CO2 and SO2 removal

A major consideration for post-combustion CO2 capture is the adverse effect of the presence of SO2 on the absorption desorption process. The most common approach is to remove the SO2 from the flue gases in a flue gas desulfurization (FGD) unit prior the CO2 recovery process. This paper reports the experimental and modeling results of a new...

Emission studies from a CO2 capture pilot plant

We report on a detailed study of emissions from a pilot-plant for CO2 capture at Maasvlakte (in the Netherlands). Three contributions to emissions were identified and analyzed: Gas phase emission, aerosols (also referred to as mist or fog) and droplets of entrained solvents. For the emission campaign at Maasvlakte aerosols were found to be the...

Emission counter-measures in post-combustion CO2 capture: demonstration at pilot plant scale

One of the objectives of the OCTAVIUS project is the demonstration of emission countermeasures for post-combustion CO2 capture. To accomplish it, an acid wash was designed and commissioned at TNO’s CO2 capture pilot plant, which is connected to a coal-fired power plant.
