| description | Natural gas demand has dramatically increased due to the emerging growth of the world economy and industry. Presently, CO<sub>2</sub> and H<sub>2</sub>S content in gas fields accounts for up to 90% and 15%, respectively. Apart from fulfilling the market demand, CO<sub>2</sub> and H<sub>2</sub>S removal from natural gas is critical due to their corrosive natures, the low heating value of natural gas and the greenhouse gas effect. To date, several gas fields have remained unexplored due to limited technologies to monetize the highly sour natural gas. A variety of conventional technologies have been implemented to purify natural gas such as absorption, adsorption and membrane and cryogenic separation. The application of these technologies in natural gas upgrading are also presented. Among these commercial technologies, cryogenic technology has advanced rapidly in gas separation and proven ideally suitable for bulk CO<sub>2</sub> removal due to its independence from absorbents or adsorbents, which require a larger footprint, weight and energy. Present work comprehensively reviews the mechanisms and potential of the advanced nonconventional cryogenic separation technologies for processing of natural gas streams with high CO<sub>2</sub> and H<sub>2</sub>S content. Moreover, the prospects of emerging cryogenic technologies for future commercialization exploitation are highlighted. |
