Sažetak
Inversion facility to the compression station is the regulation station. However the executed processes are not inversion ones. The throttling does not only bring any profit but as paradox it is necessary to supply energy for the regulation station operation. This energy should be in form of the heat, necessary for the natural gas preheating before entering the regulation device where when the pressure is reduced by throttling gas temperature drops and unwanted phenomena occurs - formation of the water vapour condensate and hydrates. The purpose of gas preheating is to prevent the above phenomena. From point of energy consumption more advantageous seems to convert the energy hidden in the form of gas pressure energy, needed for its transport, into the electrical energy or heat or at least to eliminate the energy supply needed for gas heating. Present paper Provides the analysis of the alternative possibilities of gas pressure reduction by the turbo-expander, vortex tubenad system of cyclones when regulating the gas pressure in the regulation stations.
