Development of the Solid Sorbent Technology for Post Combustion CO2 Capture Towards Commercial Prototype

Abstract

The Solid Sorbent Technology (SST) is a breakthrough technology which separates CO2 from flue gas in a continuous Temperature Swing Adsorption (TSA) fluidized bed process using solid adsorbent. The technology simultaneously delivers > 90% CO2 capture efficiency and > 95% CO2 purity with low to no process related emissions and at lower capture costs compared to state-of-the-art liquid amines technology. This paper will discuss results of a 900 h piloting campaign using Lewatit VP OC 1065 adsorbent and its impact on the cost comparison with liquid amines technology. The successful operation of the pilot plant and finalization of the test campaign marked the progression of the technology readiness level from TRL4 to TRL6.
