Ethane vs. NGLs vs. Condensates

Ethane vs. NGLs vs. Condensates

Ethane vs. NGLs vs. Condensates

(OP)
I'm trying to classify wet gas constituents based on the number of carbon atoms in each molecule.  There seems to be a lot of discrepancy in the online community regarding definitions of NGLs and Condensates.  Some materials consider ethane an NGL despite its gaseous state at stp.  Other references consider condensates a sub-group of NGLs.  Is there a clear distinction between NGLs and condensates and is ethane considered an NGL?

RE: Ethane vs. NGLs vs. Condensates

Condensate is liquid at STP.  NGL is gaseous at STP.  Normal butane boils at 31F, it is NGL.  Iso-pentane boils at 82F, it is Condensate.  Ethane boils at -127F, clearly not going to condense at normal atmospheric conditions.

I have 3 different resources that draw the line where I drew it.  I have 3 other resources that make it more complex (each different).  There doesn't seem to be a universally agreed upon definition.  I've never gone far wrong with my definition.
