alpha-Methyl esters sulfonates (alpha-MES) are anionic surfactants that are derived from biorenewable resources, offering interesting environmental and chemical properties for application in the detergent industry. A simulation of their production process was conducted using a commercial production process currently used for palm oil. Results, prices of raw materials were submitted to economic analysis, and final MES price was compared with available data for linear alkyl benzene sulfonates (LAS) prices. The results for substances properties and product streams obtained from simulation were reliable in agreement to real values. It was found that increasing methyl ester national price by 20%, 50% and the equivalent to linear alkyl benzene price, the final price of alpha-methyl ester sulfonates was lower than the current price of linear alkyl benzene sulfonates. The capital cost and payout period for a production capacity of 49,000 tons of surfactant per year were obtained. Results indicate that the process is economically feasible and can be applied to palm oil-based industries in Colombia. (C) 2010 Elsevier Ltd. All rights reserved.
