With this gas chromatographic analysis, an overall of 23 refinery heating gas components are determined in concentrations as typically found in refineries (see Table 1 for further details). Water is not analysed. The results represent dry gases. NOTE 1 Depending on the equipment used, there is a possibility to determine higher hydrocarbons as well. NOTE 2 For the purposes of this European Standard, the terms “% (V/V)” is used to represent the volume fraction (3). IMPORTANT — This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations. 2 Principle This standard defines a procedure that is used to determine all components that are present in a typical refinery heating gas, as indicated in Table 1.
NOTE The composition range in which each component can be analyzed does depend on the actual sample composition as higher amounts of a certain component may affect the detection range of other components eluting close by. The general ranges which apply to all the individual components are:  Hydrocarbons from 0,01 (mol/100 mol) up to 100 (mol/100 mol);  Non-condensable gases from 0,02 (mol/100 mol) up to 100 (mol/100 mol);  For hydrogen sulfide a range between 0,1 (mol/100 mol) up to 10 (mol/100 mol) has been found applicable. Three different analysis systems are necessary; they may be built in three separate gas chromatographs, or be integrated into one. Depending on the configuration, hydrocarbons with more than five carbon atoms are reported as a sum parameter. The composition of the refinery heating gas is used to calculate the carbon content and the calorific value. A typical procedure is described hereafter. A configuration is acceptable when the determination gives the precision as described in Clause 9. 3 Reagents and materials 3.1 Gases. 3.1.1 Hydrogen, with a minimum purity of 99,995 % (V/V). 3.1.2 Helium, with a minimum purity of 99,995 % (V/V). 3.1.3 Nitrogen, with a minimum purity of 99,995 % (V/V). 3.1.4 Air, free of oil and water. 3.1.5 Argon, as alternative for analysis system 2, with a minimum purity of 99,995 % (V/V).

4 Apparatus 4.1 Usual laboratory apparatus and glassware. 4.2 Gas chromatographic apparatus, consisting of at least three separation systems able to work simultaneously in one gas chromatograph, with a Thermal Conductivity Detector (TCD) and Flame Ionization Detector (FID) that should be available, and confirming to the requirements as given in Clause 5. SIST EN 15984:2011

A gas flow control system and gas sampling valves and switching valves are used.
Means for quantification shall be provided. NOTE Optionally a vaporizer may be used. 5.3 Columns A combination of packed and capillary columns is possible.
It shall be ascertained that a quantitative separation of all the components that need to be determined (see Table 1) is possible and that the summed total of C5+ is quantitative. Adequate separation is required between the components on all three separation systems. If cyclopropane can be determined, it shall be summed to propene. An example for a typical configuration is given in Annex A. SIST EN 15984:2011
