    Abstract

    Organic acid esters, produced from bio-based organic acids and alcohols, are truly bio-renewable, green chemicals that are promising replacements for halogenated and other petroleum-based solvents, lubricants, and plasticizers. With the uncertainty regarding the future of ethanol and other alcohols as biofuels, and with the availability of organic acids via fermentation, there is strong motivation to develop esters as viable commodity bio-chemicals to support and expand the existing bio-renewable infrastructure. Advanced reactive distillation concepts of heat-integration with side reactors for esterification of citric acid with ethyl alcohol to produce tri-ethyl citrate are put forward. AspenPlus process analysis is performed based on available kinetic data for esterification of citric acid with ethanol for an integration of pre-reactor as well as side reactors with fractionation column. Heat integration is examined for energy efficiency and maintaining temperatures in side reactors for maximizing the catalyst utilization. The concept of integrated reaction and distillation is validated by experiments using the reactive distillation facility at Michigan State University with a pre-reactor and one side reactor coupled to a distillation column. This is an abstract of a paper presented at the 2013 AIChE Spring Meeting and 9th Global Congress on Process Safety (San Antonio, TX 4/28/2013-5/2/2013).
