Dry-to-wet conversion of process gases
Thread Content
Given: Dry gas composition (on a dry basis): H2S 60%, CO2 20%, nitrogen 20%; absolute pressure of 123 kPa; temperature of 40°C. How to calculate the wet basis composition? How is water content converted?
How is the amount of water to be added in Aspen simulation determined?

However, it is possible that there exists a gas with temperature, pressure, and composition consistent with those of a known dry gas, but without any water, which contradicts the conclusion that a moisture content will be calculated. This indicates that the assumption is incorrect, meaning that the conditions for this question are not satisfied
Find the saturated vapor pressure of water at 40°C; this is the partial pressure of water. The partial pressure of water divided by the total pressure gives the water content
Thank you! :handshake{:1_90:}
