• A new technique for complete CO2 recovery via gas to hydrate conversion is presented.
• At 27 bar, 1 °C and 4000 ppm SDS, a 95% GTH conversion without agitation is obtained.
• The presented approach outperforms the other energy consuming CO2 recovery processes.
In this work the optimum operating conditions for complete CO2 recovery via gas to hydrate conversion process with minimum energy consumption is investigated. A new series of experiments are carried out at different pressures, temperatures, agitation intensities and kinetic promoter concentrations by using a newly developed fully automated GTH (gas to hydrate) energy converter. According to the presented results at the 27 bar and 1 °C and in the presence of 4000 ppm anionic surfactant sodium dodecyl sulfate (SDS) and proper amount of free water, it is possible to reach a CO2 gas to hydrate conversion of 95% without using any agitating device and without using any help additive at a completely unstirred quiescent condition which is a superb result from engineering viewpoint. The presented approach outperforms the other energy consuming CO2 recovery processes and can have significant industrial application for development of low cost hydrate-based carbon dioxide recovery plants.
