With the increase of gas rate of tray holes the velocity of liquid phase on plate only increases a little between caps.The clear liquid height was measured by communicating pipe. The results indicate that the distribution of liquid height is different from traditional trays. The clear liquid height increases with the liquid flow and the height of weir, and decreases with the increase of the gas rate and then return. The gradient of liquid level of CTST is less than that of sieve plate.

应用连通法对立体传质塔板的板上清液层高度进行了系统的测量，结果表明：立体传质塔板的板上清液层高度的分布和传统塔板的分布不同；其板上液层高度随溢流强度和堰高的增大而增大，随板孔气速的增加先降低后又有所回升；与筛板相比较，CTST的板上液面梯度是较小的。

Cause and basis for reforming the middle pressure s hi ft saturation column were analyzed,working principle of the new type of vertic al sieve plate column and its reforming situation in the middle pressure shift s aturation column were discussed,analysis and contrast were made for the operat ing parameters and economic benefit before and after reformation.
