Abstract
Shale gas, like natural gas, contains H2, CO2, CH4
and that light hydrocarbon gases needs processing to separate the gases
for conversion to higher value products. Currently, distillation based
separation is employed, which is energy intensive. Hybrid gas separation
processes, combining absorption and membranes together with
distillation require less energy and have attracted much attention. With
the property of non-volatility and good stability, ionic liquids (ILs)
have been considered as new potential solvents for the absorption step.
However, the enormous number of potential ILs that can be synthesized
makes it a challenging task to search for the best one for a specific
hybrid separation. In order to solve this problem, a systematic
screening model for ILs is established by considering the needed
properties for gas absorption process design. Rigorous thermodynamic
model of IL-absorbed gas systems is established for process
design-analysis. A strategy for hybrid gas separation process synthesis
where distillation and IL-based absorption are employed for energy
efficient gas processing is developed and its application is highlighted
for a model shale gas processing case study.
