CO2 as Chemical Feedstock

From CO2 to Plastic Foams: The Stuff That Dreams are Made of?

Dream Production is a new approach to making stuff that dreams are made of (at least if you are a chemist): Industry and scientists are working together on a project to produce chemical feedstock from CO2 which is extracted from power station flue gas emissions. The underlying reaction is revolutionary, but there is uncertainty surrounding the economic viability of the process. It remains to be seen whether this time the vision is more than just a dream.

The “Quest” Carbon Capture and Storage process: (1) The Hydrogen Unit produces hydrogen for the conversion of bitumen to synthetic crude oil. (2) The CO2 is removed from the “syngas” by contacting it with activated amine. Afterwards the CO2 is separated from the amine. (3) The purified CO2 stream is then compressed by a MAN Diesel & Turbo RG90-8 type compressor in eight stages to a discharge pressure of 130 bar. (4) This is sufficient to send the compressed CO2 about 60 kilometres via an underground pipeline to a wellhead. (5) The dense phase CO2 is injected 2.3 kilometres below the surface into a saline rock formation for permanent storage. (Picture: Shell Canada)
Compressors

CO2 Capture with Integrally–Geared Centrifugal Compressor

Oil sands have become a major source of unconventional oil: Canada produces around 1.25 million barrels per day from oil sands. Extracting the oil, nevertheless, causes CO2 emissions. Carbon capture and storage (CCS) is a new approach to hamper emissions from bitumen extraction. Compressor specialist MAN took the challenge of providing technology for the Quest CCS Project.
