In this study, the reduction of early-age strength mortar caused by traditional super absorbent polymer (SAP) was solved. Two types alkanolamines (Alkanolamine-A and alkanolamine-B) calcium nitrite were compounded with SAP as components then added into to evaluate effects on drying shrinkage. Results showed that adding two could significantly improve compressive mortar. The addition refine pore...

The removal of acid gases from gas streams by using suitable solvent like alkanolamine, commonly referred to as gas sweetening, is a technology that has been in use industrially for over half a century. In this work artificial neural network (ANN) has been used to predict the equilibrium solubility of CO2 over the alkanolamine solvents N-methyldiethanolamine (MDEA) and 2-amino-2-methyl-1-propan...

In the treatment of many fuel gases such as biogas, natural gas, syngas, and so on, tertiary alkanolamines play an important role in selective removal H2S with respect to CO2. The selectivity might be required for various reasons: more stringent specifications, optimize performance Claus unit, lower cost CO2 capture, on. H2S/CO2 is mainly kinetic and, a lesser extent, thermodynamic. A novel exp...

The role of carbon dioxide in global warming is one of the contemporary environmental issues and it is, therefore, necessary to have available technology to capture the released CO2 into the atmosphere. Amino acids have the same amine functionality as alkanolamines with similar behavior towards CO2 absorption. The solubility of carbon dioxide in potassium glycinate (KG) solutions with different...
