ABSTRACT:
A method for determining the efficiency of a carbon filter to absorb hydrocarbons from an organic amine solvent. After the solvent has passed through the filter, a sample is taken and passed through a standard gas chromatograph (GC) to measure the area counts for the hydrocarbons and the solvent. The sample does not have to have an internal standard added thereto nor does it have to be measured before it is run through the GC. The area counts are converted into actual amounts by using Reduction Factors taken from a specially-prepared calibration table. These amounts are normalized and added to give the total amount of hydrocarbons present in the solvent after it has passed through the carbon filter.
