Generally, I wouldn't mix two streams operating at a different pressures but sometimes, it is done for certain reasons. The condensate stabilizer is a distillation column operating along the pressure profile of 1136 kPag to 1106 kPag. Can a stream operating at 1002 kPag be routed to such a stabilizer? If not so, why?

No.  It is impossible for lower pressure stream to flow into higher pressure column.

Mathi,

 

Shan is absolutely correct, but you can install a pump.

Mathi,

 

In fact, you should ask: Is so, why?!

 Mathi,

 

Please note that it is always the flowrate you need to deliver and not the pressure.

 

If you route a stream as the feed to your column, then its operating pressure is no longer 1002 kPa(g), but is the column pressure plus the inlet device (if any) and the nozzle pressure drop, as It will be hydraulically balanced. But you cannot do that in a simulation software. However, as stated above you will not get the same flowrate passing through the upstream valve or pump or whatever equipment once considering 1002 kPa(g) as the operating pressure. Also, the stream phase may change depending on the equilibrium curve.

Mathi,

       The answer to your question is yes. But your question is very vague, hence the responses you get are maybe not the answer to your question. In future posts, be more specific, and provide more information.

Bobby,

 

Then, at least say: the answer to your question MIGHT BE yes...
