| Abstract: | The generated mechanism of the by product methyl acetate in PTA production and the disadvantageous effects of methyl acetate on technology and environment were recounted.By using the patent hydrolysis technique of Fuzhou University,methyl acetate as the by product of PTA plant can be hydrolyzed into acetic acid and methanol.AcOH can be reused as solvent,MeOH can be sold as product. So by using the AcOCH3 hydrolysis unit not only the unit consumption of raw material AcOH can be cut down,but also the content of AcOCH3 in off-gas can be reduced,the reduced scope can reach 72%. |
