摘 要
轻烃具有一系列优良的物理化学性质，可用于燃料、制药、燃料和制冷剂等。另外，轻烃作为一种新型清洁能源，市场前景非常可观，所以设计合理优化的轻烃分离装置，在化工生产中占有举足轻重的地位。
本设计主要针对轻烃生产工艺的分离工段进行计算，选择出合适的轻烃馏分，根据原料组成及产品指标要求，调优出合理分离顺序，通过计算理论塔板数、回流比、塔的操作压力、操作温度、产品流率、塔径、塔高，确定了填料塔的填料和板式塔F型浮阀塔板，并进行了塔板里学的校核计算。

ABSTRACT
Light hydrocarbon ,which has many excellent physical and chemical properties for man ufactacturing pharmacy,dye,gasoline and refrigerant, is widely used as raw materials, As a novel clean fuel ,light hydrocarbon has a very promising future for develapments. So,reasonable design optimization of separation device, in chemical light hydrocarbons pivotal status in the production of chemical reaction.
The design of the main production process for the separation of light hydrocarbon section in the calculation. Suit light hydrocarbon fictions from oil refinery were selected, the rational separation . sequence was oprimized according the demand for raw materials’ composition and the product target By calculating the required number of theoretical plates, reflux ratio, the tower operating pressure, operating temperature, product flow rate , high tower, tower diameter calculations, it calculate tower on the plate using the F-type floating valve tray and a tray of checking hydranulics calculation.
