Abstract:

The composition of energy consumption for qilu petrochemical company 4.0 million tons/year acrylonitrile device is analyzed. A series of energy saving technologies have been developed and applied to this process，which include wastewater incinerator recovery technology，wastewater enrichment technique，membrane rich oxygen aid-combustion technology，new efficient acrylonitrile catalyst，acrylonitrile refined recovery technology，thiamin counter-current double-effect evaporation technology. Energy consumption was reduced to 150 kg standard oil/t.AN in 2010，reached the best record of this device in history，which was 495.6 kg standard oil/t.AN in 2000.

摘要：

简要分析了齐鲁石化公司4.0万吨/年丙烯腈装置的能耗组成，有针对性地开发应用了一系列节能降耗技术，具体为废水焚烧炉余热回收技术、废水浓缩技术、膜法富氧助燃技术、新型高效丙烯腈催化剂、提高丙烯腈精制回收率技术、硫胺逆流双效蒸发技术等。一系列技术实施后丙烯腈装置的能耗值由2000年的495.6 kg标油/t.AN降低到2010年的150 kg标油/t.AN，创本装置历史最好水平。
