How to calculate or simulate the saturated water content in industrial gases

The pressure of the high-pressure compressed CO2 gas ranges from 1.5 Mpa to 2.0 Mpa, and the temperature is between 5–15°C. It is necessary to remove water from the gas to a dew point temperature of below -50°C. Assuming that the total amount of gas to be treated is 10 tons, how can we calculate the water content in the gas (in g/kg or g/m3)? Knowing the water content will make it easier to determine the size of the molecular sieve adsorption tower required for adsorption. Is there any software that can perform simulations directly?
The saturated water content in industrial gases can be calculated using the saturated vapor pressure. The specific method is as follows: 1. Determine the saturated vapor pressure based on the pressure and temperature of the gas. 2. Calculate the saturated water content in the gas based on the saturated vapor pressure and the partial pressure of water in the gas. Additionally, specialized software simulations can also be used to calculate the saturated water content in industrial gases. For example, some gas separation and purification software such as Aspen Plus and CHEMCAD provide corresponding modules for calculating the saturated water content in gases. Settings and calculations need to be done based on the specific gas composition and process conditions. -
