Containment of water vapor in natural gas prevents its transportation and applying as an internal combustion fuel. The most demanded drying technology is adsorption at high pressure. The construction of a mathematical model for predicting the process is a significant task. Through a mathematical model of the process of water adsorption from natural gas at pressures of 20–25 MPa and temperatures of 5–40°C in the presence of NaA 4A zeolite and aluminogel, commonly used dehumidifier, optimal drying conditions were selected.
