Aqueous amino acid salts are considered as an attractive alternative to alkanolamine solvents (e.g., MEA) for carbon dioxide (CO2) absorption. The kinetics of CO2 into unloaded aqueous solutions potassium lysinate (LysK) was studied using a wetted wall column at concentrations ranging from 0.25 2.0 M and temperatures 298 333 K. Physicochemical properties LysK such density, viscosity, physical solubility were measured evaluate the reaction rate constants. pathway is described zwitterion...
The effects of an antioxidant additive on polymer morphology and space charge formation have been investigated, as a function temperature, in melt-quenched films low-density polyethylene. On quenching, the additive-free crystallizes to give extensive spherulitic structures; similar objects are not seen system containing antioxidant. pulsed electro-acoustic method was then used dynamically follow both at high voltage its subsequent decay under short circuit conditions material systems. Data...
Summary Numerous saturation indices and computer algorithms have been developed to determine whether, when, where scale will form. However, prediction can still be challenging because the predictions from different models often differ significantly at extreme conditions. Furthermore, there is a great need accurately interpret partitioning of water (H2O), carbon dioxide (CO2), hydrogen sulfide (H2S) between phases, as well speciations CO2 H2S. This paper summarizes current developments in...
Aqueous monoethanolamine (MEA) is widely used for CO2 capture and has been demonstrated as an effective absorbent in many postcombustion plants. However, several disadvantages such toxicity, high volatility, solvent degradation, energy consumption were reported the practical applications. amino acid salts, particularly potassium lysinate (LysK), are considered attractive alternatives to MEA. A comparative study of characteristics aqueous LysK (2.0 M 2.5 M) MEA (5.0 was conducted this study....
Aqueous amino acid salt (AAS) solutions could be attractive absorbents for CO2 removal from flue gases. Density, viscosity, and solubility of N2O in aqueous potassium salts lysine, histidine, arginine were measured over the temperature range (293 to 353) K molality concentration (0.26 3.6) mol·kg–1. Experimental results correlated well with empirical correlations. The ion specific parameters (hAA–), based on Weisenberger Schumpe model, fitted using data aforementioned AAS systems, valid up...
Abstract Scale formation that can hinder continuous oil production is a serious problem in oilfield. Among all common scales, barite and calcite are two of the most important scales. inhibitors have been widely added to prolong induction time This study evaluates methods previous inhibition models measure predict scale presence phosphonate polymer under brine conditions. Turbidity measurement with laser light was used accurately quickly time, good reproducibility be achieved between...
