This work presents a review on the main analytical methods for estimating water content in natural gas samples of different types and with different contents. The analytical methods for sweet natural gas are mainly developed for gas under conditions of temperatures of 223.15-510.93 K and pressures of 0.1-100 MPa. The calculation of water content in sour natural gas should be calculated in a temperature range from 288.15 to 444.26 K and a pressure range from 0.5 to 69 MPa. By combining correction methods with analytical methods for sweet natural gas randomly and comparing the results with the experimental value published in the literature, it was found that the simplified thermodynamic mode & Bahadori correction method, the simplified thermodynamic mode & Mohammadi correction method, the Sloan & Bukacek-Maddox correction method and the Bahadori & Khaled correction method could reproduce with the least AAD%. Additionally, by comparing the results of these analytical methods with the experimental data in literatures, this work presented the optimum analytical methods for sweet natural gas and sour natural gas, respectively, at different temperatures and at different pressures.
