Abstract
	In the time of the economic crisis the saving of gas in its transport had came to the forefront. The main taking – over station is KS1 – Veľké Kapušany, where Russian gas enters the Slovak Republic, and therefore the throughput is very important for the entire transit. Eustream a.s. transported more than 76,2 billion cubic meters of natural gas in last year. Although the company maintains an important position in European transport systems is a very important  the effective transport of this natural gas quantity. At a time when the natural gas is not supplies from the eastern direction is more obvious to  saving gas, whether in transport or distribution. The paper describes the  throughput of each compressor set, depending on the input parameters, as well as design of the algorithm and mathematical approach in form of software. This software can be used for creating the combination of operating compressor aggregates. With this software it is possible to detect the effect of temperature on gas transport parameters of the individual aggregates. Results of the analysis is the permeability of certain types of machinery to ensure the requirements for the transport of gas daily mass in the range from 110 to 230 mil.m3 according to the input pressure, compression ratio, the ambient temperature as well as monitoring the impact of temperature of gas  in gas transport.
	The solution of the problem is described in the following three points:
* Analysis of the working characteristics of all machines that are the subject of mutual cooperation, and their incorporation into mathematical terms. 
* Defining the optimal working regimes of the individual machines. 
* Evaluation of the permeability of different aggregates
