Design Optimization of the Graz Cycle Prototype Plant
TLDR
In this paper, the design for a prototype plant based on current technology as well as cutting-edge turbomachinery is presented and the object of such a plant shall be the demonstration of operational capabilities and shall lead to the planning and design of much larger units of highest reliability and thermal efficiency.Abstract:
Introduction of closed-cycle gas turbines with their capability of retaining combustion generated CO 2 can offer a valuable contribution to the Kyoto goal and to future power generation. The use of well-established gas turbine technology enhanced by recent research results enables designers even today to present proposals for prototype plants. Research and development work of TTM Institute of Graz University of Technology since the 1990s has lead to the Graz cycle, a zero-emission power cycle of highest efficiency and with most positive features. In this work the design for a prototype plant based on current technology as well as cutting-edge turbomachinery is presented. The object of such a plant shall be the demonstration of operational capabilities and shall lead to the planning and design of much larger units of highest reliability and thermal efficiency.read more

Hybrid membrane/cryogenic separation of oxygen from air for use in the oxy-fuel process
TL;DR: In this article, the authors examined whether a hybrid membrane and cryogenic process can be utilized instead of using a large-scale O2/N2 membrane to create oxygen enriched air, which is then turned into high purity oxygen using cryogenic distillation.

Two novel oxy-fuel power cycles integrated with natural gas reforming and CO2 capture
TL;DR: In this article, two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO 2 capture and separation, where the steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer.
