According to the construction features of the gasoline fractionator and quench tower in the expansion of the ethylene plant in Qilu, corresponding HSE control measures are developed based on the hazard analysis , thus ensuring the security of the construction.
Study on the correlative changing rules of the liquid product with different feedstocks and operation condition will be significant for operation of gasoline fractionating tower.
The simulation results were compared with the actual measured data of the gasoline fractionation tower,the simulation values under different process conditions of the gasoline fractionation tower were compared too,and an improving design of the gasoline fractionation tower was proposed, namely, the gasoline fractionation tower was divided from down to up into four sections: the cooling oil recycling,moderate mass oil recycling,diesel oil separation and gasoline separation section.
Technical transformation of gasoline fractionators in ethylene plants is reviewed and discussed in this paper A techno-economic analysis for the transformation is also presented.
Because the packings on the second plate were blocked by polymer, water from the reflux pump condensed and entered into the bottom of the tower to cause the cavitation of the pump.
