摘要
对国内外常减压蒸馏装置真空系统进行调研,提出了茂名石化四蒸馏真空系统采用液环泵代替第二级蒸汽喷射器的改造方案并预测其效益,认为液环泵在常减压真空系统的应用具有充分的可行性和良好的效益,值得推广。
By investigating vacuum system in atmospheric & vacuum distillation unit at home and abroad, a revamping proposal is presented that the secondary steam ejector is replaced by liquid ring vacuum pump in Maoming No. 4 A&V distillation system, This proposal should be wildly applied because of its sufficient feasibility and economic benefit.
