摘　　要：通过对异构脱蜡装置能耗分析可知,燃气消耗、蒸汽消耗、电力消耗为主要能耗组成。通过加热炉余热回收系统改造、伴热蒸汽及汽提蒸汽用量调整、压缩机气量调节、增加机泵变频装置等方法可改善润滑油加氢异构脱蜡装置能耗状态,达到降耗节能的最佳效果。在某厂20×10^(4) t/a异构脱蜡装置的应用结果表明:节能措施累计减少该装置总能耗4.26 kgEO/t,对同类装置的节能优化有一定的借鉴作用。In order to improve the energy consumption status of lube oil hydroisomerization dewaxing unit and achieve the best effect of reducing consumption and energy saving,the energy consumption analysis of isomerization dewaxing unit shows that gas consumption,steam consumption and power consumption are the main energy consumption components.The purpose of energy saving can be achieved by reforming the waste heat recovery system of the heating furnace,adjusting the amount of heat tracing steam and stripping steam,adjusting the gas volume of the compressor,and adding the frequency conversion device of the pump.The application results of the 20×104 t/a isomeric dewaxing unit in a factory show that the total energy consumption of the unit has been reduced by 4.26 kgEO/t by energy saving measures,which can be used as a reference for energy saving optimization of similar units.
