A modeling study was performed to investigate the direct impact of amine CO2 scrubbing on the efficiency of a coal-fired power plant. The full scope of the capture process was simulated with 8 m PZ (piperazine) to estimate the steam, electricity, and

Cold rich bypass to the stripper in CO2 capture by alkanolamines will usually reduce the total heat duty. Bypass reduces the stripping steam in the overhead vapor and balances the temperature approach in the main cross exchanger. This process improve

Two campaigns were run with concentrated PZ at the University of Texas at Austin pilot plant for CO2 capture. One campaign used a simple stripper, and the next used an innovative 2-stage flash skid. Both campaigns were analyzed for their approach to

Absorption/stripping with aqueous amines is a competitive technology for CO 2 capture from coal-fired power plants. A major challenge is reducing the energy requirement in the stripper, which has contributions from the reboiler(s), pumps, and compres

A thermodynamic model in Aspen Plus ® was developed to predict properties of piperazine (PZ)/H 2 O and PZ/H 2 O/CO 2 . A sequential regression was performed to represent recently acquired loaded and unloaded heat capacity, CO 2 solubility, CO 2 acti

The objective of this work is to improve the process for CO{sub 2} capture by alkanolamine absorption/stripping by developing an alternative solvent, aqueous K{sub 2}CO{sub 3} promoted by piperazine. Modeling of stripper performance suggests that vac

Concentrated, aqueous piperazine (PZ) has been investigated as a novel amine solvent for carbon dioxide (CO 2) absorption. The CO 2 absorption rate with aqueous PZ is more than double that of 7 m MEA and volatility at 40 ∘ C ranges from 10 to 19 pp
