Hi Guys,
I have a GC that does not seperate natural gas(maily C1 and C2 with small traces of C3+), it comes as almost one peak, and for condensate (C3+) it seperates C6+, and does not seperate C3÷C5,
I Have,
1: Readjusted the split ratio Many Many times
2:Replaced the liner
3:Overhauld the injecter
4:Trimmed and reconditioned the column
5:Replaced the column
6:Overhauld the valves
7:Replaced FID board
8:Replaced FID cable
9:Overhauled FID
11:Readjusted the septum purge
12:Verified EFC is functioning
Still seperates C6+ and keeping C2÷C5 not seperated
What do you think can be the cause of this?
Looking forward to your kind answers.
Many thanks
