When designing natural gas drying equipment, the possibility of implementing an integrated approach to determine the rational technical and economic indicators of the technological devices under consideration is of great importance. This makes it possible to achieve maximum energy efficiency from the operated equipment for each specific field. One of the important tasks to be solved in the development of gas fields is the choice of a method and appropriate technological equipment according to a
