Title (EN) PROCESS FOR PRE-HEATING BOILER FEED WATER IN THE MANUFACTURE OF PURIFIED AROMATIC CARBOXYLIC ACIDS
(FR) PROCÉDÉ DE PRÉCHAUFFAGE D'EAU D'ALIMENTATION DE CHAUDIÈRE DANS LA FABRICATION D'ACIDES CARBOXYLIQUES AROMATIQUES PURIFIÉS
Abstract:
(EN) Processes for manufacturing purified aromatic carboxylic acids include: generating high-pressure steam from boiler feed water supplied to a boiler, the boiler producing a flue gas; removing a portion of the flue gas from the boiler and pre-heating the boiler feed water with removed flue gas and/or pre heating at least a portion of the boiler feed water prior to its introduction into the boiler with a first portion of the high-pressure steam; 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.
(FR) La présente invention concerne des procédés de fabrication d'acides carboxyliques aromatiques purifiés qui comprennent les étapes consistant à : générer de la vapeur à haute pression à partir d'eau d'alimentation fournie à une chaudière, la chaudière produisant un gaz de combustion ; retirer une partie du gaz de combustion de la chaudière et préchauffer l'eau d'alimentation de chaudière avec un gaz de combustion retiré et/ou préchauffer au moins une partie de l'eau d'alimentation de chaudière avant son introduction dans la chaudière avec une première partie de la vapeur à haute pression ; chauffer un acide carboxylique aromatique brut dans une zone de chauffage à l'aide de la vapeur à haute pression, la vapeur à haute pression étant condensée dans la zone de chauffage pour former un condensat à haute pression ; et purifier l'acide carboxylique aromatique brut pour former un acide carboxylique aromatique purifié ; l'eau d'alimentation de chaudière comprenant au moins une partie du condensat à haute pression.
