heal.abstract	The stripping process of 1-butanethiol, an aliphatic thiol with low threshold value and frequent presence in many effluents, was studied. Temperature was between 20° and 35°C, while pH values of 7 to 12 and gas flowrate of 200-600 mL/min were applied. The various steps of the volatilization process were diffusion of the solute from the bulk liquid to the interface, transfer across the interface, and diffusion from the interface to the bulk gas phase. The effectiveness of stripping 1-butanethiol was determined by its hydrophobicity (low aqueous solubility) rather than its pure-component volatility. Significant contribution to the total resistance of stripping rate had the slow transformation of butylmercaptide anion to its free thiol form. Increasing solution pH equilibrium was shifted towards C4H9S- and stripping rate was lowered. This is an abstract of a paper presented at the 7th World Congress of Chemical Engineering (Glasgow, Scotland 7/10-14/2005).	en
