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 ...

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 (~...

Corrosion products resulting from carbonation acting upon chloride-induced corrosion in 22 years old blast furnace slag concrete

Service life of reinforced concrete structures is usually limited to initiation of corrosion, whilst in practice corrosion in many structures is already in the propagation stage. To better understand the processes that leads to the cracking and detachment of concrete cover during this phase, the knowledge of corrosion products development in...

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...
