气相色谱分析仪在MTBE装置中的应用

Application of the Gas Chromatograph in Methyl T-butyl Ether Unit

本文介绍了气相色谱仪的工作原理,并结合MTBE装置的工艺情况,针对醇烯比比值控制系统,利用HONEYWELL公司的PlantScape集散控制系统与气相色谱仪相结合,组态编程实现随混合碳四中异丁烯含量的变化而调节甲醇的进料量的比值控制,保证反应器反应的有效进行。

This text introduced the work principle of the gas chromatograph, and combination the technological process of methyl t-butyl ether , aim at the proportion control system of the ratio of methanol and isobutene, make use of PlantScape of HONEYWELL company and the gas chromatograph to combine together, realizing the proportion control with the variety of admixture carbon fourth inside isobutene containing to adjust the methanol measure, and guarantee the reactor the validity proceeding that respond.
