Heat Balance Analysis for Esterification Heat Exchanger

Purified Terephthalic Acid (PTA for short) and Mono Ethylene Glycol (MEG) are the basic raw materials used for polyester manufacture. In the manufacture of textile grade polyester, these raw materials are converted to molten polymer (Polyethylene terephthalate) in continuous polymerisation (CP) units. CP-4 is one such continuous polymerisation unit, feeding polymer to manufacture Polyester staple fiber (PSF). in Maral Oversease limited, nimrani. The rated capacity of CP-4 is 180 tons per day of polymer, at present running 224TPD. Design of CP-4 unit is based on DU PONT technology. The paper comprises the study on CP-4 PSF esterification section heat exchanger, it discuss heat balance of the system.
