焦炉气制甲醇装置中ATR仪表设计浅谈

The Introduction of ATR Instrumentation Design in the Methanol Plant Based on Coke-oven Gas

焦炉气是炼焦过程的副产品,除部分返回炼焦炉用作加热燃料外,剩余的气体主要用作城市居民的燃料气,也有相当数量通过火炬燃烧放空。随着国家节能减排的深入,利用焦炉气制甲醇一方面减少对大气CO2的排放,另一方面还可以产生经济效益。开发了纯氧部分氧化制合成气的技术,在焦炉气制甲醇装置中采取ATR技术,其主要包括仪表选型、复杂控制及联锁逻辑三方面的内容。合理的设计实现对装置的工艺过程实时监控、设备的安全运行,提高工艺气转化率。

The coke oven gas is the by-product in coking process and is flammable. Partial coke oven gas returns to coke burner as heating fuel, the surplus gas is largely applied as urban fuel gas, and quite a lot is vented to flare stack. With the support from the state for energy-saving and pollution-reducing project, the methanol project based on coke oven gas is a favorble option： it can reduce CO2 emmission and also yield economic benefit. After years＇ exploration and research, a synthetic gas production technology by the partial oxidation of pure oxygen has been developed, therefore ATR technology will be widely applied in this process. Instrumentation design plays an important role in application of ATR technology.
