Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis

Abstract

Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous solutions selected to evaluate the potential for CO2 capture at post-combustion conditions with high pressure solvent regeneration. The set-up was modified to enable analysis of ammonia and CO2 in the vapor phase using FTIR®. Solid formation in the liquid phase was monitored using optical probes FBRM® and PVM® to determine maximum CO2 loadings for the precipitation-free range.
