摘　　要：对1万t/a异戊烯装置设计的优化项目进行了考察,验证了设计的有效性;分析了装置运行情况,提出了不同负荷下醚化操作的优化条件;优化了醚解催化剂的投用条件,减少了二甲醚的生成,降低了装置的甲醇单耗;控制异构化反应器的温度和叔戊醇含量,保证了2-甲基-1-丁烯的转化率,提高了产品中的2-甲基-2-丁烯的含量;异戊烯侧线出料口下方增加了1米填料后改善了产品的品质,降低了产品中其他组分的含量;装置的标定表明:装置能稳定运行,数据可靠,达到了设计指标。The effectiveness of the improvement on the design of the new annual 10kt isoamylene plant was re- viewed. The optimization conditions of operation for the etherification of isoamylene and methanol to form tertiary amyl methyl ether（TAME） under different treatment were proposed. Lower temperature of the decomposition reactor of tertiary amyl methyl ether could reduce the generation of dimethyl ether in initial stages, therefor the consum- mation of methanol was cut down. Temperature and content of tert amyl alcohol in isomerization reactor were con- trolled to maintain the high conversion level of 2-methyl 1 butylene（2M1B） to 2 methyl 2 butylene（2M2B）, isoamylene with high content of 2M2B would be obtained. Other components in the product reduced with the one meter packing height increment below the discharge port of the column for refining isoamylene. Calibration result displayed that the plant could run stably and reached the design target.
