Pressure drop model of multicyclone separator at high-pressure

为了准确预测和计算天然气输气管线用旋风分离器的压降,在归纳常压下单管和多管旋风分离器的压降计算公式,以及现场测量高压下多管旋风分离器的压降基础上,建立了高压下多管旋风分离器的压降计算模型。利用实验验证压降模型的可靠性,实验结果表明,常压下单管、多管旋风分离器和高压下多管旋风分离器的压降计算模型都能准确地计算出对应旋风分离器的压降值,计算值与测量值之间的误差较小。因此,利用建立的高压下多管旋风分离器压降计算模型能够准确地计算出不同压力和温度下多管旋风分离器的压降值,从而为天然气用旋风分离器的选型提供技术支持。

Based on concluding the pressure drop models of single and multicyclone separator under atmosphere pressure,and on-site measurement pressure drop values,a pressure drop model has been built up to predict and calculate the pressure drops for multicyclone separators operating at different pressures and temperatures in natural gas transportation.The reliability of pressure drop models has been calibrated by experiments,the results showed that the pressure drop models could calculate exactly the pressure drop values for corresponding cyclone separators,and the differences of pressure drop values between calculated by models and measured by experiments could be ignored.Therefore,the pressure drop model of multicyclone separator at high-pressure can be used to calculate the pressure drop values for multicyclone separators under different pressures and temperatures.
