Kruonis pumpkraftverk är ett pumpkraftverk i Litauen för lagring av överskottsenergi.. Energilagring utnyttjas för att spara utvunnen nyttig energi som sedan kan användas vid en …

Can we recover hydrogen from a mixture using pressure swing adsorption (PSA)?

The research focused on the technological feasibility of recovering hydrogen from the mixture, employing pressure swing adsorption (PSA). The withdrawal process can continue over several months, over which the pressure in the reservoir decreases and the composition of the mixture varies.

What is a PSA system integration strategy?

The system integration strategies described refer to a PSA unit processing low temperature shifted syngas (i.e. cold PSA process). Interesting potentials are expected by PSA processes operating at higher temperature (i.e. hot PSA process). In such case, the process configuration remains rather similar, with some substantial differences.

Does a PSA process have a lower energy penalty?

to the PSA process. In spite of the different energy consum ption patterns, the final net electric efficiency is similar for the two cases tested, with PSA displaying a sl ightly lower energy penalty. Regarding the CO separation performance,

Does a single stage PSA separating Co from a shifted syngas improve performance?

However, the literature generally focuses on single stage PSA designs [10,14,42]. Table 3 reports characteristics an d performance of some PSA processes for separating CO from a shifted syngas. One may notice that the energy consumptions involved are significantly lower than in the post -combustion cases. Pre-combustion cases are

What is the potential for PSA in pre-combustion systems?

Good potential for PSA is envisaged whit hot gas separation processes, especially with sorption-enhanced processes. Furthermore, the complexity of the arrangements in pre-combustion cases may open room for interesting alternative system configurations, like power and H 2 coproduction layouts. 1876-6102 © 2017 The Authors.

Can PSA be integrated into a power plant?

The integration into power plant does not entail significant issues, with a good potential for retrofitting old plants. An excessively large footprint of the separation unit has been reported, which seems to question the feasibility of PSA. In pre-combustion applications, prospects for improving adsorbent materials and processes are noticed.
