Siemens Amino Acid Salt Technology with lowest emissions and highly efficient reclaiming system

Amine based Technologies Siemens PostCap Technology

Additional washing steps on top of the absorber required, due to evaporating amines and nitrosamines

Not required in Siemens process, AAS and nitrosamines are non-volatile

Even with additional washing steps amine based technologies cause solvent emissions

No solvent emissions predictable in Siemens process

Nitrosamines predictable in the known processes have different sources

formed by means of the direct nitrosation of the solvent within the capture process

formed from emitted amines (solvent degradation products) in the atmosphere.

The PostCap solvent as well as nearly all degradation products and any formed nitrosamines / nitramines are non-volatile.

Even without additional washing steps, Siemens PostCap process has demonstrably no solventemissions.

Measured nitrosamine emmisions caused of PostCap process is zero.

By-products can be separated for disposal in a 2-step reclaiming system.

Fossil fuels will maintain a big share in global electricity production and carbon capture is one important and necessary measure to cope with climate change

Post-combustion technology comprises a proprietary chemical absorption process which is retrofitable to coal and gas fired power stations

Siemens offers an unique portfolio of high efficient power plants as well as pre- and post-combustion carbon capture solutions to reduce and/or avoid CO2 release

Summary

The so called PostCap process exhibits an outstanding environmentally friendly character and is very energy efficient.

The advantages of the PostCap process were successfully verified in the Staudinger pilot plant. It is ready to be applied in demonstration scale projects.

PostCap Process fits well in the GCC Environment
