由于费托油存在轻质化问题,针对轻白油装置的扩能改造问题进行了研究。在原有设备及产品分离条件的基础上,利用模拟软件对原有系统进行模拟,采用能量衡算、气液相平衡衡算及管路压降衡算结合的方法,分析了装置扩能技术改造的可行性。经模拟验证,装置负荷可提升至原有负荷的130%~150%。

Because the oil produced by Fischer-Tropsch process is light,the capacity expansion and renovation of light white oil unit are studied.On the basis of the separation conditions of the original equipment and products,a simulation software is employed to simulate the original system.The method combining energy balance,gas-liquid phase equilibrium balance and pipeline pressure drop balance is used to analyze the feasibility of the technical renovation and capacity expansion on the unit.Through simulation verification,the load of the unit can be increased to 130%-150% of original load.
