What is Post Combustion Carbon Capture?
Post-combustion carbon capture (PCC) with amines is a technology that uses an amine solvent to remove carbon dioxide (𝐶𝑂2) from flue gas. The process is regenerative, meaning the solvent can be reused after the 𝐶𝑂2 is captured. Our Trainer: Carbon Capture Trainer focuses on Gas Absorption, a mass transfer operation in which a solute vapor is absorbed from its mixture with an insoluble gas using a liquid solvent in which the solute vapor is soluble. The separation of gas mixtures and recovery of the components usually involves a regenerable absorbent. In the natural gas processing industry, sulphur compounds and CO2 are removed by absorption by an aqueous amine solution. In this trainer, an air / CO2 mixture emulates the raw flu gas stream. The amine is regenerated and recycled through the process. The trainer is equipped with industry-typical process measurement and control devices, providing a realistic training environment in which the students are exposed to the many available technologies associated with carbon capture. |
