甲醇制丙烯工艺中液烃吸附剂再生过程探析

Regeneration process analysis of absorbent for methanol to propylene process

与乙烯工艺技术类似,鲁奇公司的甲醇制丙烯(MTP)工艺过程中为控制后续分离单元中设备和管道中的水含量,防止管道冻堵,对于压缩后的物料采用干燥剂进行干燥以除去其中的水分。从工艺过程出发,介绍了甲醇制丙烯工艺技术中所采用的液烃干燥剂的再生操作过程。

Similar to ethylene process technology, in order to control water content in equipment and pipe and prevent freezing in separation unit , MTP process of Lurgi adopts absorbent to eliminate water content for compression down- stream stream. The article introduced absorbent regeneration operation process of methanol to propylene in aspect of process.
