Background
The Fischer-Tropsch synthesis olefin is a liquid coal-to-oil product which is prepared by indirectly liquefying coal and takes normal alkane and alpha olefin as main components. The main components of Fischer-Tropsch synthesized olefin are 50% -60% of alpha olefin, 35% -45% of n-alkane with five to sixteen carbon atoms, a small amount of isoparaffin, cycloparaffin and isoparaffin, and the impurity is a trace amount of moisture. With the development of coal-to-liquid technology, the production capacity of Fischer-Tropsch synthesized olefins in China is improved year by year, and the olefins are used as raw materials for preparing poly-alpha-olefins, so that the economic efficiency is good.
In the process of preparing poly alpha olefin, a rectifying tower is needed for many times, the traditional rectifying tower is generally a regular stainless steel packed tower or a tongue-shaped floating valve plate type tower, and because the tower plates are all of a planar structure, part of liquid phase substances are easy to accumulate on the tower plates in the downward advancing process of the liquid phase substances, so that the separation is incomplete, and the inaccuracy of related data is affected.
