Abstract:
Methanol carbonylation with improved aldehyde removal includes: (a) scrubbing light ends and aldehyde impurity from vent gas with an absorber solvent; (b) stripping absorbed light ends and aldehyde impurity from the absorber solvent to provide a vent-recovered light ends stream; (c) purifying the vent-recovered light ends stream to remove aldehyde impurity; and (d) recycling purified light ends from the vent-recovered light ends stream to the production system.
