DESIGN OF COMPLEX COLUMNS USING COLUMN PROFILE MAPS 

Specify and calculate all variables to satisfy the external mass balance, that is, product compositions and/or flowrates. 

Specify the reference reflux and a split ratio (/ and in side stripper, and 

Determine through the appropriate Equations 6.13 6.18 R/s. s for the remainder of the column.

The general design procedure consists of a number of steps to be taken into consideration. These include ... 

Heater-treaters, used to make the final separation of water from oil at lease sites, should be designed on the basis of lab analysis of the produced fluid. However, such data are rarely avaiiame, ana this article provide a general design procedure that can supplement or, to ome extent, replace the more rigorously scientific approach. 

A flash suppressor, however, can incorporate features that reduce the intensity of the noise. If this type muzzle device can be developed to the point where both flash, and noise can be reduced to acceptable limits, two knotty problems become solved siniultaneousiy. A large amount of effort has been expended on flash suppressors considerably less on noise inhibitors. A measure of success has been achieved in the suppression of noise thru exptn. No general design procedures, either theoretical or empiri-... 

No critically reviewed design procedure exists for ESPs. However, one suggested general design procedure (L. Theodore, personal notes) is provided below. 

Provide a general design procedure for an absorption column.

The above rules can be put together into a general design procedure at Pinch, as illustrated by the Fig. 10.33. Firstly, the stream count rule is checked. If not fulfilled, a first stream split is performed to balance streams, cold stream above the Pinch, or hot stream below the Pinch. Then the CP s rule is checked for matches close to the Pinch. If not fulfilled, again stream splitting is executed, this time opposite to the first. Note that the above rules might be not respected away from Pinch. 

To improve this situation fundamental research is necessary in order to find general design procedures and limits of operation for the process which are independent of the particular column type. This can only be achieved through cooperation between researchers in industry and universities. The European Federation of Chemical Engineers established a Working Party in Extraction for this purpose which recommended liquid systems for testing extraction columns so that the results would be comparable.
