Undersea Separation of CO2 from Natural Gas through Ionic Liquids
The candidate will collaborate with researchers from the project C2C- Center to Center Research Centre for Greenhouse Gas Innovation – RCGI. Summary of the program and projects can be found at the RCGI website (http://www.rcgi.poli.usp.br/)
In brief, the project's primary goal is to study the use of ionic liquids to remove CO2 from light hydrocarbons streams at a unit set on the subsea level. The outside environment poses a much higher pressure than on the surface. Therefore, the separation system should also perform at high pressure conditions to allow the reduction of the equipment wall thickness. Thus, leading to lower equipment costs and lower initial investment capital (CAPEX). In addition, since the operating pressure would be much higher at such conditions, lower energy demands would be required to compress CO2 into the reservoir. Ionic liquids' low vapor pressure, tunable structure, and high CO2 selectivity properties should enhance the CO2 capture at the subsea conditions. However, its complex interaction and high-pressure conditions pose a modeling challenge to conceptual processes development. Furthermore, few experimental data are available under conditions of high pressure; therefore, predictive models, such as UNIFAC-Lei and COSMO-SAC, should be applied and assessed. High-pressure phase equilibrium experiments should be performed to acquire the missing data. Thus, the parameters of suitable EoS models, such as PR, SRK, CPA, and PC-SAFT, should be regressed and evaluated. An appropriate separation method such as absorption or membrane should be selected and modeled to perform CO2 separation. Finally, conceptual separation processes must be developed and adopted through competency, protection, and environmental metrics.
