焦炉气制甲醇装置中ATR仪表设计浅谈

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

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 ...
