Gas Expansion

Gas expansion with Spilling: targeted use of modular technology.
Highly efficient electricity generation by recovering energy from natural gas transport networks – that is what the Spilling natural gas expansion plant offers you. Electricity can thus be generated in gas transfer stations at maximum primary energy efficiency and minimal CO2 emissions. 

Natural gas expansion plants exploit the pressure difference between transport and distribution network. The pressure of the downstream distribution network is reduced by the gas expanders and the electrical energy is gained power used to drive a working machine e.g.  a compressor. The power plant is installed parallel to the conventional gas pressure control lines and the supply of the downstream network is secured. Since the natural gas only has to be pre-heated to moderate temperatures, usually only to approx. 100 °C or less before being expanded, various heat sources can be used for this purpose: district heat, industrial waste heat, heat from hot water boiler plants and combined heat and power plants.

In view of the increasing scarcity of primary energy sources and rising electricity costs, Spilling gas expansion plants provide an economically interesting, ecologically sound and efficient possibility to generate electricity decentrally – and not just for utility companies and industrial companies with large natural gas purchases.

Dimensioning is performed under consideration of the respective gas pressure ratios and the gas procurement conditions. Due to the individual configuration of the number of cylinders and pressure staging, the modular system of the Spilling engines permit an optimal adaptation to the very different conditions of gas pressure control stations.
