Implementing the mathematical model of the throughput of compressor station aggregates

Abstract

The main aim of the European union energy policy is to ensure a continuous supply of natural gas for the member states. The Russian gas is transported through the Belarus, Ukraine, Slovakia (SR) and Czech Republic to Germany. This article shortly describes the transit system of Slovakia and compressor station KS1 -Vel'ké Kapušany. The throughput of this compressor station plays an important role in gas transport, because this station is the entry to the transit system of SR. To find the best combination of the aggregates used in gas transport a simulation algorithm was devised. We present the architecture of this simulation software together with the description of its development phases. The software was evaluated against data gained from the KS1 compressor station operation. The combinations of aggregates were found as dependent on inlet pressure, ambient temperature and compression ratio.

Energy and exergy recovery in a natural gas compressor station – A technical and economic analysis

“…A shell-and-tube heat exchanger (2) is installed as the heat recovery unit. The generated hot water at a temperature level of 150°C/70°C can directly be supplied to the heating network Unit I, and requires an additional intermediate heat exchanger (6) to integrate with the heating network Unit II, operated at lower temperature (90/70°C). The required additional network length is 500 m.…”

“…The optimum operation should provide minimum total cost, which consists of the cost of fuel, maintenance, start-up and shut-down cost components and the cost of over-supply (unnecessary operation above the demand). A method for building a simulation model of a CS based on the characteristics of machinery was shown by Vaszi et al [6]. http Ernst et al [7] analyzed the operation of a CS in relation to the demand for the compressed gas.…”
