Abstract
Abstract An apparatus for heating and vaporizing a rich oil sample, mixing the sample vapors, diluting the vapor sample with a diluent gas, mixing the diluted vapors sample, extracting first and second volumes of a vapor sample, and selectively extracting and passing first and second different groups of hydrocarbons from the respective first and second vapor samples to separate first and second detectors.

An apparatus for preparing a rich oil sample for analysis, comprising: heating means for heating the sample to a preselected temperature; a pressure regulator within the heating zone for reducing the pressure of the sample and vaporizing the sample; conduit means for passing the sample to a hereafter mixing tank; a mixing tank having a chamber and inlet and outlets in communication with the chamber and being attached to the conduit means at the inlet of said mixing tank for receiving the vaporized sample and mixing said sample therein; dilution means connected to the outlet of the mixing tank for receiving vapors therefrom and adding a diluting gas thereto; a dilution tank having a longitudinal axis, a chamber, and first and second opposed ends; means connected to the dilution means and the first end of the dilution tank for delivering the diluted sample vapors from the dilution means into the chamber of the dilution tank and causing the vapors to move about the longitudinal axis of the dilution tank; first and second sample valves serially connected to the second end of the dilution tank in communication with the chamber of said tank for receiving first and second samples therefrom; a first column connected to the first sample valve for receiving the first vapor sample; means within the first column for separating a first group of hydrocarbons from the vapor sample and passing said first hydrocarbon group therefrom; a second column being connected to the second sample valve for receiving the second vapor sample; and means within the second column for separating a different second group of hydrocarbons from the vapor sample and passing said second hydrocarbon group therefrom
