PDU-Scale Experimental Results of CO2 Removal With Amp/Pz Solvent

Abstract

This paper provides a discussion concerning results of CO 2 removal from a gas mixture by the application of aqueous solutions of ethanoloamine (MEA) and 2-amino-2-methyl-1-propanol (AMP) promoted with piperazine (PZ). The studies were conducted using a process development unit. Research of such a scale provides far more reliable representation of the actual industrial process than modelling and laboratory tests. The studies comprised comparative analyses entailing identical energy supplied to a reboiler as well as tests conducted at similar process efficiencies for both solvents. The results thus obtained imply that using AMP/PZ enables reduction of the solvent heat duty. Moreover, while using AMP/PZ temperature decrease was also observed in the columns.

Experimental results of split flow process using AMP/PZ solution for post‐combustion CO2 capture

“…This study is a continuation of previous PDU‐scale research on CO 2 removal by 30 wt% MEA and 30/10 wt% AMP/PZ solutions using a split flow process . Both solvents were compared as well as changes to the system operating characteristics, especially L/G ratio, and have been discussed in the preceding paper.…”

“…The experimental studies conducted comprised comparative tests of different lean amine split flow process configurations at the optimum L/G ratio, which was established in previous paper . In this paper, the standard configuration (S), where the entire lean amine stream is delivered to the absorber top section (Fig.…”

Environmental issues and process risks for operation of carbon capture plant

“…Thanks to the research conducted on pilot installations [4,5], carried out by research team from the Institute for Chemical Processing of Coal, a concept of DCCP installation was prepared, for Łaziska Power Plant in Łaziska Górne, belonging to the TAURON Wytwarzanie S.A. The basic technological element of the DCCP installation is a CO2 removal module with amine solution (30% water solution of ethanolamine (MEA)) [6] or water solution with 30% AMP (2-amino-2-methyl-1-propanol) and 10% piperazine (PZ) [7]. The CO2 removal module consists of a few process parts: amine solution storage, CO2 absorption, heat exchange and solution regeneration.…”

Laboratory Studies of Post-combustion CO2 Capture by Absorption with MEA and AMP Solvents

“…As suggested, this result is related mainly to the unit heat exchangers. The comparison can be found in [30].…”
