what is used as coolant at the existing deC2 column ovhd.?Acually we dont have in our unit dec2 column but we are only have C3 liquefaction (change the phase of C3 from hot gas to liquid storage tempreture at -45 F) and C4 liquefaction (change the phase of C4 from hot gas to liquid storage...
To clear things up , I think we are not in the same direction . This is a simple draw of our process
To clear things for me again I will ask questions if turboexpander could replace that system or not .
Thank for being...
propane compressor has 6 stages attach file is similar to what we have .
electric motor with 16.7 MW drive the compressor .
what i want to know, is my idea valid or not ? if yes how is the process going to be and is there any real example world-wild ...
thank you for your comments
i will one more time to explain our process in more details .
after all products are fractionated . C3 at 100 F and 260 psig stream(header) head to refrigeration Unit which consists of four main parts.
The first part called flash drum that received the C3 from C3...
i am working at C2+ fractionation plant NGL .
We fractionate the C2+ into many products including propane ,butane and c5 . Following that process, we refrigerate the C3 and C4 separately to storage temperature using close loop system include flash drum, receiver drum, compressor, and mechanical...
