Abstract

|
An experimental study of the absorption of CS in the secondary amine diethanolamine(DEA) was performed in this work. The primary objectives were to investigate an analogy between N2O and CS permitting estimation of the physical solubility and diffusivity of the sulfur gases in the reacting amino solutions. The solubilities of CS in water at 25, 40 and 6 has been measured. The data show fair agreement with previous literature values. The solubility of CS in 5-25 weight % polyethylene glycol has been measured in order to investigate a possible analogy between CS and NO The diffusivities of CS in water and the reaction rate between CS and DEA has been measured at 25 and 4, using a wetted sphere apparatus operated at approximately 1/3 atmospheres pressure, which is a previously untried method.
