使用新型炉管 实现降本增效

Effect and evaluation of the transformation of the cracking furnace convection section

大庆乙烯装置为了实现降本增效,将裂解炉原有的"W"型四程炉管更换为高选择性的"对程U型"炉管,以提高乙烯收率,实现装置效益最大化。

The Daqing ethylene plant in order to achieve the effect of reducing,the original cracking furnace 'W' type four furnace tube replacement process of high selectivity 'to process U' furnace tube,in order to improve the ethylene yield,realize the benefit maximization device.
