OXYCOAL-AC: Towards an integrated coal-fired power plant process with ion transportmembrane-based oxygen supply

Abstract

The cooperative project OXYCOAL-AC aims at the development of a zero-CO 2 -emission coal combustion process for power generation. The scope of the research comprises a multitude of aspects. This article focuses on membrane-based air separation modules and their design for oxycoal conditions, the specifics of coal combustion in a CO 2 /O 2 atmosphere including related burner design as well as the cleaning of hot flue gas from oxycoal combustion.

Oxygen permeation through Ca-contained dual-phase membranes for oxyfuel CO2 capture

“…In recent years, most of researches were focused on their potential application in the oxyfuel process for oxygen production and CO 2 capture [11][12][13], because the net output efficiency of power plants can only be slightly degraded compared with the state-of-the-art cryogenic distillation technology. For the integration of the MIEC membrane into the oxyfuel process, fossil fuels combust with the permeated oxygen carried by CO 2 , and part of CO 2 is recycled as a sweeping gas for the oxygen separation process, whereas the remained CO 2 is captured and sequestered after steam condensation.…”

A new CO2-resistant Ruddlesden–Popper oxide with superior oxygen transport: A-site deficient (Pr0.9La0.1)1.9(Ni0.74Cu0.21Ga0.05)O4+δ

“…Therefore, oxygen-transport membranes should not only exhibit a high oxygen ux, but also show good stability under CO 2 -containing atmospheres. 3,4 Acceptor-doped perovskite-type oxides A 1Àx A x 'B 1Ày B' y O 3Àd (A, A' ¼ La, Sr, Ba; B, B' ¼ Fe, Co, Nb, etc.) have been investigated extensively as OTMs over the past two decades.…”

Worldwide innovations in the development of carbon capture technologies and the utilization of CO2

“…Energy losses in a range of 6 to 10% points seem to be possible. 64,[72][73][74] Chemical looping research is actually focusing on investigating suitable materials. Efficiency losses are estimated to be approximately 8% points.…”
