SNG Test Facility

Synthetic natural gas (SNG for short) refers to a gas mixture similar to natural gas with methane as its main component, which is produced by synthesis.
SNG synthesis is a possible way of storing large quantities of electrical energy as chemical energy, even over long periods of time. The starting materials for SNG synthesis are hydrogen and carbon monoxide or carbon dioxide (synthesis gas).
The system consists of the synthesis gas mixing section, a gas preheater, a cascade of up to three reactor trays and connected online analysis of the product gas.
Between the reactors, the heat of reaction can be dissipated via heat exchangers. Due to the variable character of the plant, different synthesis gas compositions, reactor configurations and waste heat utilization concepts can be tested and data can be determined, e.g. for modelling. It is possible to couple the plant with an electrolyzer and thus investigate power-to-gas concepts in their entirety.
