A 30% aqueous solution of waste methyldiethanolamine (MDEA) can be regenerated, reused in gas treatment, and its residue used as a secondary raw material another area production. (HOCH 2 CH ) NСH 3 is separated from water by vacuum-extraction method. MDEA destroyed part remain the column. In laboratory conditions, it was shown that degree purification destruction products this method 60 to 78%....

The present study evaluated the environmental impacts of post-combustion CO2 capture and recovery via membrane–gas absorption processes. We have used SimaPro v.9 packages with Ecoinvent v3.5 database employing two different methods, ReCiPe 2016 Endpoint (H) Midpoint (H), considering a fundamental methodological framework to determine most environmentally friendly experimental condition. Life cy...

In order to reduce global CO2 emissions, capture based on absorption in an amine/water mixture is established method. To develop such processes, correct physicochemical properties like densities and viscosities are important.The first objective of this work explore mathematical correlations for fitting viscosity data aqueous Monoethanolamine (MEA) Methyldiethanolamine (MDEA). A second evaluate ...

Density and Speed of sound have been measured for pure components such furan, (DMF) 2-5-dimethylfuran, MDEA (n-methyldiethanolamine), DEG (diethylene glycol), TEG (triethylene DMA (dimethylacetamide) using Anton Paar (DSA-5000) vibrating U-tube densitometer in a temperature range 278.15 to 343.15 K ambient pressure (100 kPa). density speed furan + MDEA, DEG, TEG, 303.15 whereas DMF DMA, the is ...

Efflux is an important resistance mechanism in Staphylococcus aureus, but its frequency in patients with bacteremia is unknown. Nonreplicate bloodstream isolates were collected over an 8-month period, and MICs of four common efflux pump substrates, with and without the broad-spectrum efflux pump inhibitor reserpine, were determined (n = 232). A reserpine-associated fourfold decrease in MIC was ...
