Patent ID: 7964029

Claim:
An assembly for collecting samples from a flowstream, the flowstream comprising a liquid and a gas under pressure, or a liquefied gas, or a gas at or near or above its critical pressure and temperature, the assembly comprising: 1) a splitter vessel having i) at least one wall having an interior surface defining a chamber, and ii) a first outlet and iii) a second outlet, said first and second outlet ends being open and tapered to have a diameter narrower than the diameter of the chamber, said first outlet for discharging gas having a position at the top of said chamber and said second outlet positioned at the bottom of said chamber for discharging liquid; 2) an angled inlet tube for delivering the flowstream to an interior wall of the splitter vessel at an angle below horizontal; and 3) a collection container, connected to the outlet for liquid flow with a connection tube, that receives liquid flow from the splitter, wherein the connection tube diameter is sized to allow the liquid flow to drain from the splitter into the collection container while allowing quiescent gases from the collection container to flow into the splitter.
