| titleOfInvention | Terephthalic Acid Reduction Process PSD Prediction Method and Terephthalic Acid Quality Control Method Using the Same |
| abstract | The present invention comprises the steps of performing an oxidation and reduction process in a reactor in the production of terephthalic acid; And crystallizing the terephthalic acid slurry subjected to the reduction process in a first crystal bath, a second crystal bath, and a third crystal bath, wherein the terephthalic acid reduction process PSD {particle size distribution} prediction method is supplied to a reactor of a reduction process. Determination step of determining the content of terephthalic acid to be; And measuring the difference between the terephthalic acid content and the pressure difference between the reactor, the first crystallization tank, the second crystallization tank, and the third crystallization tank, and calculating the average particle size of the terephthalic acid and the particle size distribution of the terephthalic acid by the equations (5) and (6). Provided is a terephthalic acid reduction process PSD prediction method. According to the disclosed terephthalic acid reduction process PSD prediction method, the size of a product particle having a great influence on the operation and quality of downstream products such as polyester filament, fiber, and film Particle size distribution (PSD) Quality values can be quantified and measured in advance in an accurate and easy way to minimize the occurrence of quality defects and to perform stable operation. |
