Abstract: PURPOSE: VOC(Volatile Organic Compounds)s treatment method and facility are provided to treat VOCs stably and effectively by a direct burning mode without a processing facility or an additional energy source. CONSTITUTION: A VOC(Volatile Organic Compounds)s treatment facility comprises a demister(201), a fan, gas sensors(101,102), a heater(203), a flame arrestor(103), and a shut-off valve(104). The demister separates and collects moisture and mist from VOC gas. The fan sucks and moves VOC. For LEL(Lowest Explosive Limit) to be maintained, the gas sensors measure the concentration of the VOC sucked and control the amount of external air. The heater keeps the temperature of the sucked VOC constant and prevents the VOC from having a temperature lower than a boiling point.

Abstract: The present invention relates to a method of preparing a polyester resin having high yellowness index, of which yellowness index may be improved to less than a predetermined degree by excluding a chemical material such as a tinter and controlling inorganic materials through improvemet of processes only, and a polyester resin having high yellowness index prepared by the method. According to the method of preparing the polyester resin having high yellowness index, in which ethylene glycol and terephthalic acid react to prepare the polyester resin, ethylene glycol and terephthalic acid are mixed at a molar ratio of 1.0 to 3.0 and stirred to prepare a slurry, and a polymerization reaction is conducted to recycle for the use in a preparation process of a polyester resin. According to the polyester resin having high yellowness index and the method of preparing the same, the inorganic materials included in ethylene glycol and terephthalic acid as impurities may be controlled. Thus, contaminating problems by heavy metals due to the use of the tinter such as cobalt acetate for managing the yellowness index which is important physical properties in an existing method of preparing common polyester are not generated. The increase of the yellowness index of the polyester may be simply restrained, and the devaluation of a product due to the deterioration of transparency may be prevented.
