摘　　要：提出了现有对二甲苯生产装置提高产量的两个有效途径 :(1)优化原料组成。生产能力为 180kt/a的对二甲苯联合装置 ,如果将原料中C8芳烃含量从 3 0 .5 %提高到 40 % ,C9芳烃与甲苯比例相应调整 ,其产量可提高到192kt/a。 (2 )在优化原料的基础上 ,将二甲苯异构化I 9催化剂更换为I 10 0 (或 3 0 0 )系列催化剂 ,装置的生产能力将增加到 2 5 0kt/a ,年增效益 70 44× 10 4RMB $ ,半年内便可收回投资。选择这两个途径 ,需结合具体情况具体分析 。Two effective routes enhancing the production of the p xylene unit were put forward.(1) Optimizes the composition of the feedstock.For a p xylene combination unit with processing capacity 180000 t/yr,if the content of C 8 aromatics in the feedstock was increased from 30.5% to 40% and adjusted C 9 aromatics/methylbenzene to a proper ratio,the production of the unit can be enhanced to 192000 t/yr.(2) Replaces the I 9 catalyst for isomerization of p xylene by the I 100(or I 300) series catalysts.The processing capacity of the unit can be increased to 250000 t/yr and annual economic benefits increased by 7044×10 4 RMB$.
