i want to know whats the difference between seperator and component splitter and need manual calculation of splitter..

Component splitter works as its name says: it redistributes each of the components present in the feed stream in between the so called "overhead" and the "bottom" streams. Depending on specified conditions of both outlet streams, you may need to include an energy stream feeding the splitter as well.

There is no process connection between the separator and the splitter. Separator provides segregation of two different phases, whereas component splitter segregates each and every component from the feed stream based on the specified component split, and it is not interested in phase separation. This UnitOp is frequently used to represent processes that cannot be accurately modeled (or there is no need to do so) e.g. like Mol Sieve dehydration unit, where we simply use the component splitter to remove H2O from the feed stream, and use the remaining stream for further/downstream processing. In this particular case, you would set the H2O split as "1" for overhead and "0" for bottom, and for all other components you would specify split as "0" for overhead and "1" for bottoms stream exiting the component splitter.

i cant find component splitter theoritically any where..iots just the simulating softwares uses them..i used it insted of liquid liquid extraction column but cant find how to do the manual calculation of component splitter or liquid liquid extraction..please sort it out
thanx for replying

Can you post a sketch made in Excel and show us what do you have to accomplish? It is difficult to track your line of thoughts this way.

Component splitter is not a piece of real equipment - it does not exist as such. It is just an artificial unit operation available in commercial software, created for several purposes. One of those purposes is explained in my previous post.
