Abstract

Summary

The separation of the carbon dioxide (CO2) is one of the key issues of Carbon Capture and Storage (CCS). The conventional CO2 separation technology have some disadvantages including the relatively large facilities, a considerable investment, complex mechanical work, and the possibility of having a negative impact on the environment. The supersonic separation process, a revolutionary technique for CO2 removal, provides an environmentally friendly-facility by eliminating the need for chemicals. In present study, we propose a novel CO2 separation using the supersonic separator. The separation characteristics of carbon dioxide in supersonic flows are investigated using the real gas equation of state and Reynolds stress model. The results show that the gas mixture is accelerated to supersonic speed and results in a low pressure and temperature, which is good for the nucleation and condensation of the carbon dioxide. The helical vanes generate the swirling flow, which is further strengthened in the Laval nozzle. The centrifugal acceleration can reach approximately 8.08×10λ6 m/sA2 that will separate the CO2 droplets from the gas-liquid mixtures.
