Abstract: A process for preparing acrylic acid, in which an acrylic acid-comprising product gas mixture obtained by catalytic gas phase partial oxidation of a C3 precursor of acrylic acid is fractionally condensed in a condensation column provided with internals ascending into itself with side draw removal of crude acrylic acid and with liquid phase draw removal of acrylic acid-comprising acid water, and acrylic acid present in acid water is taken up into an extractant and then removed from the extractant and recycled into the condensation column, or taken up in aqueous metal hydroxide, or sent to further purification of the crude acrylic acid.

Abstract: An absorbent for removing acidic gases from a fluid stream, comprising an aqueous solution a) of at least one metal salt of an amino carboxylic acid and b) of at least one acidic promoter, where the molar ratio of b) to a) is in the range from 0.0005 to 1Ø The acidic promoter is selected from mineral acids, carboxylic acids, sulfonic acids, organic phosphonic acids and partial esters thereof. The absorbent exhibits, compared to absorbents based on amino acid salts, a reduced requirement for regeneration energy, without significantly reducing the absorption capacity of the solution for acidic gases. In a process for removing acidic gases from a fluid stream, the fluid stream is contacted with the absorbent.

Abstract: A 3C or more of precursor is subjected to heterogeneously catalyzed gas phase partial oxidation with molecular oxygen in solid-state catalyst to obtain product gas mixture. The product gas mixture is reduced by direct cooling, passed into a condensation column, and crude acrylic acid is conducted, and acid water is disposed. A residual gas mixture is recycled, and crude acrylic acid is subjected to thermal separation process. The acrylic acid is taken in organic solvent to form organic extract, and thermal separation processed to form acrylic acid. A 3C or more of precursor is subjected to heterogeneously catalyzed gas phase partial oxidation with molecular oxygen in solid-state catalyst at elevated temperature to obtain product gas mixture comprising acrylic acid, steam and secondary components. The product gas mixture is reduced by direct/indirect cooling, passed into a condensation column equipped with separating internals, allowed to ascend into the condensation column, and fractionally condensed. The crude acrylic acid comprising water and secondary components, is conducted as the target product from the condensation column through a side draw (A1) disposed above the feed point of the product gas mixture into the condensation column, and acid water comprising acrylic acid and secondary components is disposed above the side draw (A1) through a liquid phase draw (A2). A residual gas mixture comprising secondary components having lower boiling points than water at the top of the condensation column and a bottoms liquid comprising acrylic acid and conversion products, and secondary components having higher boiling points than acrylic acid from the bottom space of the condensation column, is recycled after cooling with reflux liquid, into the condensation column, and the crude acrylic acid is subjected to thermal separation process and purified. The acrylic acid in a portion of acid water not recycled into the condensation column is taken up from the acid water into an organic solvent by extraction with the organic solvent to form an organic extract comprising acrylic acid. The acrylic acid is removed from the organic extract using thermal separation process, and the acrylic acid removed from the extract is recycled into the condensation column into the aqueous solution of a metal hydroxide. Thus, acrylic acid is manufactured.
