Extended flue gas trials with a membrane-based pilot plant at a one-ton-per-day carbon capture rate

Abstract

a b s t r a c tA membrane-based pilot plant for carbon dioxide capture from the flue gas of a coal-fired power plant has been installed and operated at the National Carbon Capture Center in Wilsonville, Alabama, USA. The membrane system is sized to treat flue gas containing one ton per day of carbon dioxide. Stable operations for three extended runs conducted over a period of two years have been achieved with both pulverized coal and simulated natural gas flue gas. Carbon capture rates up to and over 90% were achieved with full-scale Polaris™ modules in individual trials that ran up to 1800 h. Both cross-flow and countercurrent sweep spiral-wound modules demonstrated effective and stable carbon capture performance. This paper describes the experimental correlations that were developed, and summarizes the observed performance envelopes resulting from the combination of selected operating process conditions, equipment, and modules.

“…5 Polymeric membranes based on poly(ethylene oxide) (PEO) have come to larger pilot scale production and are tested at several industrial sites for performance and stability in the environment of natural gas or coal red power plants ue gas streams. 6,7 The permeance and selectivity of developed PEO membranes lead to effective extraction of CO 2 from the ue gas while the modelling of separation process economy shows that membrane separation systems are competitive to other considered methods of CCS. 8 The selectivity of the developed membranes has reached the limit dened by the ideal selectivity of PEO based materials used for formation of the selective layer.…”

A techno-economic case study of CO2 capture, transport and storage chain from a cement plant in Norway

“…Two possible types of membranes are considered. The Polaris polymeric membrane developed by MTR [13] is believed to be at an advanced stage of development and testing [14] and is referred to as the reference membrane in several studies [15]. The Fixed Site Carrier (FSC) membrane was developed by NTNU [16] and has been tested at Norcem Brevik cement plant [17].…”
