Abstract
This work provides new viscosity data of unloaded and partially carbonated aqueous monoethanolamine-piperazine (MEA-PZ) solutions at temperatures between 303.15 and 373.15 K and at a N2 pressure of 400 kPa. In both cases, the viscosity of MEA-PZ solutions was measured at three different concentrations of PZ at 5, 10, and 15 wt % and by keeping the concentration of MEA constant at 30 wt %. For the carbonated solutions, measurements were performed by varying the concentration of CO2 between 0.13 and 0.55 mol of CO2/mol of amines. A simple empirical equation and a modified Setschenow equation used to correlate the viscosity of unloaded and CO2-loaded MEA-PZ solutions, respectively, provide a good representation of the experimental data.
Highlights
Chemical absorption using aqueous alkanolamines is considered the commercial-ready technology to capture flue gas such as carbon dioxide (CO2) from industrial processes
The widely used alkanolamine for treating flue gas this way is aqueous monoethanolamine (MEA).[1−3] In a typical CO2capture process,[2,4] aqueous MEA reacts with flue gas containing carbon dioxide 124-38-9 (CO2) to produce MEA-carbamate in the absorption column
We reported in this work new experimental viscosity for aqueous MEA-PZ blend for both unloaded and CO2loaded solutions
Summary
Chemical absorption using aqueous alkanolamines is considered the commercial-ready technology to capture flue gas such as carbon dioxide (CO2) from industrial processes. The flue gas in this case is normally treated after combustion of the fuels, and this method of treating the flue gas is preferred since the process can be retrofitted onto existing power plants. The widely used alkanolamine for treating flue gas this way is aqueous monoethanolamine (MEA).[1−3] In a typical CO2capture process,[2,4] aqueous MEA reacts with flue gas containing CO2 to produce MEA-carbamate in the absorption column. The MEA-carbamate is sent to a hightemperature stripper to liberate the CO2 gas. The treated gas is forwarded for another purpose or sent to storage.
