限流孔板在精对苯二甲酸装置中的应用

THE APPLICATION OF RESTRICTION ORIFICE ON REFINED TEREPHTHALIC ACID UNIT

限流孔板在国外先进的工艺装置上已经取得了较为广泛的应用 ,而在我国自行设计的装置上限流孔板的应用还未能得到充分的重视。研究、借鉴国外装置上限流孔板的成功应用 ,对于装置的降低投资、简化操作。

The restriction orifice has been applied extensively on foreign advanced process unit.But restriction orifice can not be paid attention in domestic process unit design by ourselves.To study and dram on the succes ful experience of restriction orifice applied on the foreign process unit,are full of meaning for decreasing investment,simplifying operation and safe service of unit.
