Abstract

Concentrated, aqueous piperazine (PZ) has been developed as an attractive solvent for use in CO₂ capture for coalfired power plants because of its low degradation rate, high CO₂ capacity, and high CO₂ absorption rate, but its use may be limited by precipitation of solids at low and high CO₂ loading. In this work we examine the effects of blending diamines, such as hexamethylenediamine (HMDA), 1,4-diaminobutane (DAB), or bis(aminoethyl)ether (BAE), with PZ on thermal degradation of the amine. The presence of the diamine does not catalyze the thermal degradation of piperazine and appears to degrade independently of piperazine; in particular, HMDA and BAE appear to have thermal degradation rates that are competitive with piperazine.
