Just so they sell or use the NGL’s and not just flare it off.
I’m even okay with them burning it, if the pay the mineral owner for it.
But if you separate at/near the rail yard, they make rail cars suitable to haul propane and other NGL’s and folks pay pretty decent money for a whole rail car full of it.
The idea is just to get the higher pressure components out of the rail car designed for lower pressure oil.
