High Efficient Industrial Carbon Capture Technology
Industrial Research Ltd (IRL) has made a breakthrough that enables the world’s most efficient carbon dioxide capture technology to become commercially viable. IRL Research Scientist Robert Holt is leading the multi-disciplinary team that is investigating the development of a cost-effective enhancement to an existing technique that uses limestone for the capture of carbon dioxide emissions from fossil fuel power combustors. IRL has been awarded $350,000 over three years by the Foundation for Research Science and Technology to further develop its technology.
The process is designed to capture carbon dioxide from coal fired power stations and other industries that emit significant amounts of the greenhouse gas.
The lime cycling process uses limestone, a relatively abundant and inexpensive material. It is heated to around 900 degrees centigrade to become lime, which is a very effective material for absorbing carbon dioxide.
When post-combustion flue gas is passed through the lime in a fluidised bed, the CO2 is captured. The process is then reversed to transform the lime back into limestone, which is then used again to capture more CO2.
The 95 per cent pure CO2 that is produced can be compressed to about 3% of its original volume and can then be stored efficiently or used in another industrial process. This process has been known for many years but until now it has not been efficient enough to be considered commercially applicable.The IRL team confirmed that exposing the lime to steam reopens its pore structure and enables it to absorb CO2 efficiently again.
