We calculated ideal-gas thermochemical properties (molar enthalpy, entropy, Gibbs energy, and heat capacity, Cp) for 30 primary 12 secondary alkanolamines their neutral, protonated, car...

Nowadays, many researchers are focused on finding a solution to the problem of global warming. Carbon dioxide is considered be responsible for “greenhouse” effect. The largest emission industrial CO2 comes from fossil fuel combustion, which makes power plants perfect point source targets immediate reductions. A state-of-the-art method capturing carbon chemical absorption using an aqueous alkano...

the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

One of the alternatives to reduce CO2 emissions from industrial sources (mainly oil and gas industry) is capture. Absorption with chemical solvents (alkanolamines in aqueous solutions) most widely used conventional technology for Despite competitive advantages solvents, technological challenge improving absorption process apply alternative reducing energy demand increasing captured per unit sol...

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...
