High-Pressure Condensate Recycle in the Manufacture of Purified Aromatic Carboxylic Acids |
| 摘要 |
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. |

1. A process for manufacturing a purified aromatic carboxylic acid comprising:
generating high-pressure steam from boiler feed water supplied to a boiler; heating a crude aromatic carboxylic acid in a heating zone using the high-pressure steam, whereby the high pressure steam is condensed in the heating zone to form a high-pressure condensate; and purifying the crude aromatic carboxylic acid to form a purified aromatic carboxylic acid; wherein the boiler feed water comprises at least a portion of the high-pressure condensate. |
