高粘度物料精馏的研究与应用

A Research and Application of High Viscosity Material's Distillation Process

研究了高粘度物料精馏的特点与解决方法 ,对大塔径 (2 0 0 0mm)、低板间距 (2 85mm)、高粘度 (10～5 0Pa·s)物料的精馏过程 ,采用新型导向筛板替代原泡罩塔板进行技术改造。在计算机上研究了精馏工艺优化方案 ,工程上合理排布导向孔与塔板分块。技术改造达到了扩产、节能、提高产品质量与回收率、稳定生产的目的。技改设备投资仅 2 2万元 ,年增经济效益 32 1万元 ,投资回收期不足 2

New type flow guided sieve tray was adopted to replace orignal bubble cap tray in technology reform of distillation column with diameter 2000mm,distance between two near tray 285mm and material's viscosity 10～50Pa·s.Distillation technology and plan were researched on computer.Flow guided opening and tray cutting were resonablly arranged.The technololgy reform reached the targets of increasing capasity,saving energy,raising product quallity and recovery rate,stablling production process etc.The equipment investment is RMB 0 22 million and its recovery period is less than 22 days because the increased profit was RMB 321 million every year.
