轻汽油醚化工艺中分馏塔浮阀塔板的优化设计

Light gasoline etherification process fractionating tower equipment optimal design of plate parts

分馏塔在轻汽油醚化装置中的主要任务是将催化汽油中初馏点～75℃馏分中的叔戊烯、叔己烯和叔庚烯分离出来(轻汽油),并将其作为汽油醚化的原料。分馏塔的基本功能是为气液两相提供充分接触、分离的机会,使传热和传质过程迅速而有效地进行,并且使接触后的气液两相及时分开,互不夹带。论述了分馏塔塔主要零部件-塔板的优化设计举例。

Fractionating tower Light gasoline etherification unit＇s main task is to the beginning of catalytic gasoline fractions boiling point - 75 ℃ in the tert-pentene, tert- hexene and tert-heptene isolated （light petrol） and petrol ether as a of raw materials. Fractionating tower＇s basic function is to gas-liquid two-phase to provide adequate contact separation of opportunities to heat and mass transfer process is quick and effective manner, and to make contacts gas-liquid two-phase separated in time, mutual non-entrainment. This article discusses the main components fractionation Tata- Tray optimal design.
