The application techniques of effective removal of mercury in natural gas have received much attention due to the requirements for environmental protection,equipment safety and human health. In this paper,the advance in several typical removal technologies of mercury in natural gas such as physical adsorption,chemical adsorption,solution absorption and low temperature separation was briefly reviewed. The application progress in the existing mercury removal agents for the removal of mercury in natural gas, including active carbon mercury adsorbents,supported metal adsorbents,halogenated or sulfur loading active carbon and other mercury adsorbents,was summaried. The influence of temperature and humidity of natural gas in inlet on the effect of mercury removal was investigated. It was pointed out that low tempera-ture and humidity were benificial to mercury removal.
