导向浮阀塔板是在F1型浮阀塔板的基础上开发成功的 ,较早应用于炼油装置的常减压蒸馏塔 ,在提高轻油的收率上获得了较大的经济效益 ,在化工产品的分离中应用较少。该项目在醋酸装置的精馏工序中 ,采用先进的导向浮阀塔板改造原有的F1型浮阀塔板 ,达到节能降耗 ,提高醋酸收率 ,增加醋酸产量 ,提高经济效益的目的 Pilot valve tray is developed on the basis of F1-type valve tray, which is used in the atmospheric and vacuum distillation column of the refinery as early as possible to obtain greater economic benefits in increasing the yield of light oil. Chemical products used in the separation of less. The project in the distillation process of acetic acid plant, the use of advanced guided valve tray to transform the original F1-type valve tray to achieve energy saving, increase the yield of acetic acid, increase acetic acid production and increase economic efficiency purposes
