Grinding aids are commonly used in cement manufacture to reduce electrostatic forces between powder particles and agglomeration. Alkanolamines known also influence the hydration of aluminate phases cement. This study assessed effect TEA, TIPA DEIPA addition on LC3 systems. It was observed that these molecules have an enhancing reaction LC3. They promote ferrite C3A, lead higher amounts hemicarb...

In this work, 4-diethylamino-2-butanol (DEAB) as a new type of alkanolamine solvent is used for CO 2 capture in hollow fiber membrane contactor (HFMC). A model describing the gas and liquid reactions transport inside under wetting or non-wetting conditions was built. The countercurrent flow natural considered model. To investigate influence on decarburization efficiency, DEAB compared with othe...

Abstract Absorption by aqueous solutions of alkanolamines is the most mature technology for removing carbon dioxide (?? 2 ) from natural gas, off-gases power engineering, and other mixtures. The possible presence oxygen in gas mixture being treated or air leakage into absorption treatment system leads to oxidative degradation amine deactivation liquid with formation a wide range corrosion-activ...

The ion mobility (IMS) spectra of the alkanolamines, monoethanolamine (MEA), 3-amino-1-propanol (PRA), 4-amino-1-butanol (BUA), and 5-amino-1-pentanol (PEA) with acetone and 4-heptanone reagent gases have been measured using a hand-held spectrometer. Monomer and dimer peak patterns were observed for all the alkanolamines with acetone reagent gas. Drift times of monomer and dimer ion clusters fo...

As one of the simple and efficient routes to access two-dimensional materials, liquid exfoliation has received considerable interest in recent years. Here, we reported on high-efficient liquid exfoliation of hexagonal boron nitride nanosheets (BNNSs) using monoethanolamine (MEA) aqueous solution. The resulting BNNSs were evaluated in terms of the yield and structure characterizations. The resul...
