Abstract
In one embodiment, the invention is to a process for producing an acrylic acid, comprising the step of reacting, in a carbonylation system, carbon monoxide with at least one reactant in a reaction medium under conditions effective to produce a crude alkanoic acid stream comprising alkanoic acid. Preferably, the reaction is an exothermic carbonylation reaction. The process further comprises the step of removing from the carbonylation system at least a portion of heat generated by the carbonylation reaction and transferring a portion of the heat to a heat transfer system that utilizes at least one steam condensate stream. The process further comprises the step of conveying at least a portion of the heat transferred to the heat transfer system of the condensation reaction zone and/or the condensation separation zone.
