HIGH-PRESSURE CONDENSATE GENERATION IN THE MANUFACTURE OF PURIFIED AROMATIC CARBOXYLIC ACIDS

Processes for manufacturing purified aromatic carboxylic acids include: generating high-pressure steam from boiler feed water supplied to a boiler; heating a crude aromatic carboxylic acid using the high-pressure steam, whereby the high pressure steam is condensed to form a high-pressure condensate;...

Zusammenfassung:Processes for manufacturing purified aromatic carboxylic acids include: generating high-pressure steam from boiler feed water supplied to a boiler; heating a crude aromatic carboxylic acid using the high-pressure steam, whereby the high pressure steam is condensed to form a high-pressure condensate; and purifying the crude aromatic carboxylic acid to form a purified aromatic carboxylic acid. The boiler feed water includes at least a portion of the high-pressure condensate and makeup boiler feed water from at least one additional source.
