| Abstract: | The exist PTA plant is modified to realize the efficiency recovery of methyl acetate.At the same time,the original recovery tower system direct steam injection heating is modified into indirect heating.Froced back flow are realized on the top of the column.The methyl acetate is efficiently and fully recovered.The AcOH combustion is decreased.The plant long time running are realized.The AcOH unit consumption is reduced obviously. |
