RAG Austria is one of the largest energy storage companies in Europe focusing on the sustainable use of depleted natural gas reservoirs for underground gas storage and the conversion of renewable energy to hydrogen. Upon extracting the gas from the reservoirs, a main gas-processing step is the dehydration of the gas by extracting water vapor from the water saturated gas stream. Two different dehydration methods are applied: gas dehydration by adsorption to silica gel and gas dehydration by absorption, also known as glycol dehydration.

In this session, we’ll give an overview of the successful development and application of simulation models for both dehydration methods using Simscape^®. The physical description of the adsorption and absorption processes could be implemented successfully by applying the Simscape custom component functionalities to build detailed models of the adsorption and absorption column dynamics. We’ll present several use cases that show an excellent agreement with measurement data recorded at the gas dehydration plants.
