Machine learning for industrial processes: forecasting amine emissions from a carbon capture plant

One of the main environmental impacts of amine-based carbon capture processes is the emission of the solvent into the atmosphere. To understand how these emissions are affected by the intermittent operation of a power plant, we performed stress tests on a plant operating with a mixture of two amines, 2-amino-2-methyl-1-propanol and piperazine ...

Conclusions from 3 years of continuous capture plant operation without exchange of the AMP/PZ-based solvent at Niederaussem – insights into solvent degradation management

A many times heard mantra of solvent degradation management in amine-based post combustion capture is “keep the solvent clean” to minimize solvent consumption. It is assumed that the amine losses would decrease by the removal of metals, degradation products, and reactive trace components which are captured from the flue gas, like NO2 (as...

Degradation behaviour of fresh and pre-used ethanolamine

The oxidative degradation of previously used ethanolamine from three different CO2 capture pilot plants was studied in a laboratory-scale degradation setup. Different solvents behave differently under the same experimental conditions, indicating that different solvent contaminants, resulting from different operational conditions, can act either...

Impact of high capture rates and solvent and emission management strategies on the costs of full-scale post-combustion CO2 capture plants using long-term pilot plant data

Pilot plant campaigns are critical to our understanding of the performance of solvent-based post-combustion capture processes. During the ALIGN-CCUS project, longterm pilot plant runs in the Niederaussem lignite-fired power plant were conducted, that aimed to investigate solvent degradation and emissions management and capture rates beyond 90%....

Advancements in ship-based carbon capture technology on board of LNG-fuelled ships

The International Maritime Organization has set clear objectives towards drastically reducing greenhouse gas emissions the coming decades in the maritime sector. While different ways to reduce emissions are already proposed, these are not expected to generate high CO2 abatement rates (in the case of fuel saving measures) or to be available and...

CCUS scenarios for the cement industry: is CO2utilization feasible?

In this work, four illustrative CO2 capture, utilization and storage chains are investigated in order to evaluate the economic feasibility of CCUS technologies in connection to the cement industry. A CCS reference chain in which 90% of the CO2 emissions (or 0,694 MtCO2/y) are stored in a saline aquifer is first studied. Due to emissions related...

Special Case Studies in Sustainable Carbon Capture

This chapter presents discussion of four selected case studies for sustainable carbon capture. The first case study is a high-level techno-economic integration study for CO2 capture in the waste to energy (WtE) sector, which may result in negative emissions, as a large part of the CO2 is biogenic. Integration of CO2 capture in this sector is...

Update on post-combustion carbon capture and storage on LNG fuelled vessels

The maritime industry has set clear objectives towards reducing greenhouse gas emissions in the coming decades. Ship based carbon capture (SBCC) could play a large role in reducing these emissions on the short term. This study gives an update on the work that has been conducted towards carbon capture and storage on LNG fuelled vessels. This is...

ALIGN-CCUS: results of the 18-month test with aqueous AMP/PZ solvent at the pilot plant at Niederaussem – solvent management, emissions and dynamic behavior

After a 13,000-hour test campaign with aqueous 30 wt% MEA (2-aminoethanol) solvent at the CO2 capture pilot plant at Niederaussem, another long-term test was carried out as part of the ALING-CCUS project. This test ran for more than 12,275 hours with aqueous AMP/PZ (2-Amino-2-methyl-1-propanol/piperazine) solvent, named CESAR1 (3.0 molar AMP (~...

Carbon capture and storage and the sustainable development goals

For carbon capture and storage (CCS) to be a truly effective option within the efforts being made to mitigate climate change, it must be sustainable. An assessment is therefore required regarding how the deployment of CCS will positively contribute towards the achievement of the UN’s Sustainable Development Goals (SDGs) by 2030. This assessment...

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...

CO2 capture in geothermal application

For the generation of geothermal heat, hot water is pumped from geothermal wells. Natural gas is dissolved in the brine under reservoir conditions and co-generated from these wells during production. It can be used in a combined heat and power (CHP) system.

Post-combustion Carbon Capture and Storage on LNG Fuelled Ships

Post-combustion CO2 capture by absorption is a mature technology that has been implemented in many industrial applications to decrease CO2 emissions from large point sources. As demonstrated in this work, the CO2 capture process can be implemented onboard as a retrofit technology, thus enabling timely implementation; a key element for the...

Results of the 18-month test with MEA at the post-combustion capture pilot plant at Niederaussem: new impetus to solvent management, emissions and dynamic behaviour

An almost continuous 13,000 h long-term testing under real operating conditions was conducted at the post combustion capture pilot plant in the Niederaussem lignite-fired power plant, with a 30 wt% aqueous monoethanolamine (MEA) solvent solution. The capture plant at Niederaussem shows lower solvent consumption and emissions in comparison to...

In-situ experimental investigation on the growth of aerosols along the absorption column in post combustion carbon capture

The amine-based post combustion carbon capture process is one of the most advanced and preferred technologies to reduce CO 2 emissions from point sources like power plants. The emissions of amine from capture plants is one of the biggest challenges faced by this technology. These emissions typically occur by means of aerosol/mist formation. To...

Lab scale investigation on the formation of aerosol nuclei by a wet electrostatic precipitator in the presence of SO 2 in a gas stream

Aerosol based emissions have been reported from several Post-Combustion CO 2 capture (PCCC)pilot plants. These are known to pose a significant challenge in large scale implementation of PCCC processes. The aerosol nuclei are in the form of H 2 SO 4 droplets or Na 2 SO 4 particles, typically less than 0.1 ?m and 0.255 ?m, respectively. A wet...

Ship-based carbon capture onboard of diesel or LNG-fuelled ships

Total shipping carbon emissions were approximately 938 million tonnes CO 2 in 2012. Zero emission shipping options rely on the use of electricity or alternative fuels, such as blue hydrogen or ammonia. However, that requires major modifications to the ships and the logistics of fuel distribution. As a transition solution, which can be...

Consensus statement understanding health and malnutrition through a systems approach: The ENOUGH program for early life

Nutrition research, like most biomedical disciplines, adopted and often uses experimental approaches based on Beadle and Tatum’s one gene—one polypeptide hypothesis, thereby reducing biological processes to single reactions or pathways. Systems thinking is needed to understand the complexity of health and disease processes requiring measurements...
