This infrastructure provides facilities and methods to conduct breakthrough experiments as well as full PSA and TSA cycles. The columns (height: 1.2 m; inner diameter: 0.25 m) are manufactured in-house from two concentric stainless steel pipes that act as a jacketed column and are equipped with thermostats enabling control of the column temperature. Five thermocouples are placed regularly inside each column. Two mass flow controllers are used to control the feed flow rates, while the system pressures are controlled by two back pressure regulators mounted downstream of each column; additionally, the pressure drop across the beds is measured using four pressure transducers installed at the inlet and at the outlet of the columns, respectively. A combination of automatically and manually activated valves allows for a flexible choice of a PSA/TSA cycle. Online monitoring of the outlet gas composition is achieved by a mass spectrometer. The mass spectrometer enables the monitoring of many different components, in a range of concentrations in the order of ppm.
TA11.2 provides facilities and methods to conduct breakthrough experiments as well as full PSA and TSA cycles. This lab pilot plant was built in house and is therefore very flexible. Adaptation and small changes can be easily implemented. The mass spectrometer has a very high resolution (0.1 s), which also allows monitoring of fast processes.
The installations are designed for CO2 capture research. In-house activity based thermodynamic and kinetic models can be used to model the experimental results. Additionally in-house lab equipment for offline analysis of solids related to crystallization research (XRD, TGA, SEM, PSD) can be used to find the speciation in the solids. The current users at ETH have obtained many scientific achievements based on the services offered by the infrastructures, including EU projects, industrial and National Funded Research projects, and have produced many peer-reviewed scientific papers.
