Top ten CO2 facts
As of November 2011, CO2 in the Earth's atmosphere is at a concentration of 390 ppm (0.039%) by volume.
Drax power station (4000MW, ca. 7% UK supply) produces up to 50,000 tonnes CO2 per day.
A 750ml bottle of Champagne has a typical pressure of over 5 times atmospheric pressure and contains the equivalent of over 4 litres of CO2 under normal conditions.
The body produces approximately 1 kg of CO2 per day per person, which equates to almost 29,000 kg of CO2 per person over a typical lifetime.
CO2 extinguishes flames, and some fire extinguishers, especially those designed for electrical fires, contain liquid CO2 under pressure.
A children’s sweet called Pop Rocks is pressurised with CO2 gas at about 40 bar (580 psi). When placed in the mouth, it dissolves (just like other hard sweets) and releases the gas bubbles with an audible pop.
Human activities such as the combustion of fossil fuels and deforestation have caused the atmospheric concentration of CO2 to increase by about 35% since the beginning of the age of industrialization.
CO2 is an end product in organisms that obtain energy from breaking down sugars, fats and amino acids with oxygen as part of their metabolism.
Photosynthesis uses CO2 and water to produce sugars and occasionally other organic compounds, releasing oxygen as a waste product.
Plants can grow up to 50% faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions.
Welcome to C-Capture
AMINE-FREE CO2 CAPTURE
C-Capture Ltd is a spin-out company from the Chemistry Department at the University of Leeds. Utilising their extensive knowledge of CO2 (carbon dioxide) based chemistry, they have adapted a bottom-up approach to designing solvent systems for the removal of CO2 from gas streams. CO2 is considered to be a ‘greenhouse gas’ and its release into the atmosphere is thought to be one of the leading contributors to global warming.
C-Capture’s proprietary technology aims to remove or ‘scrub’ CO2 from gas streams, preventing it from entering the Earth’s atmosphere.
C-Capture has developed novel solvents that as CO2 passes through, it is reversibly absorbed onto/into the mixture. Once the CO2 has been ‘captured’ it can be separated and then released as a pure stream and transported for safe, long-term storage or used in other manufacturing processes. One of the main uses for carbon capture technologies is in the field of CCS - or Carbon Capture and Storage - which aims to prevent CO2 that is generated in the production of electricity, mainly from coal-fired power stations, from entering the atmosphere. This technology significantly reduces the amount of CO2 released into the atmosphere – by up to 95% – and makes electricity generation a much more environmentally friendly process.
