AB  - In the wake of an unprecedented growth of the market demand for natural gases, exploration and
utilization are necessary for high impurity wells worldwide. Therefore, it has become vital to conduct research
work on the development of optimized and automated processes for removal of natural gas impurities mainly
CO<sub>2</sub> . Conventionally, CO<sub>2</sub> from natural gas streams are absorbed by amine solutions or other appropriate 
chemical solutions but cryogenic separation technology is suitable for use if the CO<sub>2</sub> content of the natural gas 
is high. In cryogenic separation, the process principle involves the separation based on the difference
in volatility and desublimation. The cryogenic separation process is classified into conventional, nonconventional
and hybrid techniques. Conventional process involves Liquid-Vapor (L-V) based separation. The
non-conventional method includes Solid-Vapor (S-V) based separation while hybrid technique utilizes both
conventional and non-conventional methods. Cryogenic research including both L-V and solid-vapor S-V
based separation has recently shown several advantages and to enhance the separation performance and
energy reduction, a novel concept of cryogenic hybrid (L-V and S-V) process is also discussed.
