Abstract
Abstract A sample of a fluid hydrocarbon mixture is prepared for analysis by withdrawing a fluid sample from a test zone. The sample is mixed with a polyhydroxy compound, such as glycerine, which serves to sweep oils, tars and any polymeric materials through the sample lines. The polyhydroxy compound is then removed from the sample to remove any entrained oils, tars and polymeric materials. The sample is further treated to remove water prior to being passed to an analyzer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
A method of preparing a hydrocarbon-containing gas stream for analysis by removing water, oils, tars and polymerizable constituents therefrom, comprising: contacting and scrubbing the gas sample with a polyhydroxy compound containing 2 to 4 hydroxy groups and having 2 to 5 carbon atoms per molecule, such contacting and scrubbing being conducted at a temperature greater than about 212° F.; separating the contacted materials into a first vaporous phase and a first liquid phase; lowering the temperature of the first vaporous phase below about 212° F.; separating a second vaporous phase and a second liquid phase from the cooled first vaporous phase; separating a hydrocarbon phase and a water phase from the second liquid phase; mixing the separated hydrocarbon phase with the second vaporous phase; and vaporizing the resulting mixture.
Claim 2
Independent Claim

Claim 6
Dependent Claim
42 words
The method of claim 1 wherein said first vaporous phase is passed through a zone containing solid particles which remove traces of oil contained in said vaporous phase before the temperature of said first vaporous phase is lowered below about 212° F.
Claim 7
Independent Claim
135 words
A method for selectively, controllably separating constituents from a gas sample having a temperature greater than about 200° F. for subsequent chromatographic analysis, comprising: contacting and scrubbing the gas sample with a volume of glycerine at a first preselected temperature greater than about 212° F.; separating the mixture into a first vaporous phase and a first liquid phase; lowering the temperature of the first vaporous phase to a second preselected temperature less than about 212° F.; separating a second vaporous phase and a second liquid phase from the cooled first vaporous phase; separating a hydrocarbon phase and a water phase from the second liquid phase; mixing the separated hydrocarbon phase with the second vaporous phase to form a resultant mixture; and heating the resultant mixture to the first preselected temperature for vaporizing said resultant mixture.
Claim 8
Independent Claim
135 words
