"Due to national strategic reserves and to smooth seasonal and short-term peaks of natural gas consumption it is stored in underground reservoirs. During storage it is being saturated by water vapor from the repository. Before the further distribution gas must be dehydrated to meet the transportation parameters specified by the gas distributors. The paper describes a new energy saving gas-drying technology that uses a supersonic passage of the gas through a nozzle. In the nozzle pressure and temperature of the gas is being transformed into its velocity. Temperature of gas drops below the dew point of water vapor and nucleation of droplets proceeds. At the inlet to the nozzle swirling flow is induced by static blades. Therefore condensed water is separated from the rest of the gas by centrifugal forces. The disadvantage of this method is sensitivity on inlet parameters (flow rate, temperature and pressure). The goal of this paper is to formulate mathematical-physical model of gas flow in the nozzle. Technical design which solves the problem of unsteady inlet parameters is proposed. Basic geometry and industrial applications are discussed." . "[8B2290EFE882]" . . . . "109" .
