European foreword
This document (EN 15984:2022) has been prepared by Technical Committee CEN/TC 19 “Gaseous and
liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat
of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2022, and conflicting national standards shall be
withdrawn at the latest by August 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15984:2017.
This revision contains a new informative Annex with estimated precision data for selected components
in refinery gas.
This document is based on a DIN Standard [5] with the same scope.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
1 Scope
This document defines a gas chromatographic analysis for the determination of the composition of fuel
gases, as used in refinery heating gas. These results are used to calculate the carbon content and the lower
calorific value.
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 document, the terms “% (V/V)” is used to represent the volume fraction (φ).
IMPORTANT — This document does not purport to address all of the safety problems associated with its
use. It is the responsibility of the user of this document to establish appropriate safety and health
practices and determine the applicability of regulatory limitations.

4 Principle
This document 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 can 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 results in the precision as described in Clause 11.
