BS EN 15984:2011 pdf download.Petroleum industry and products一Determination of composition of refinery heating gas and calculation of carbon content and calorific value一Gas chromatography method.
BS EN 15984 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 European Standard, the terms “% (V/V) is used to represent the volume fraction (q).
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 samp’e composition as higher amounts of a certain component may affect the detection range of other components eluhng dose by. The general ranges which apply to all the individual components are:
Hydrocarbons from 0,01 (mol/100 mol) up to 100 (molilOO mol), Non-condensable gases from 0,02 (moLIlOO mol) up to 100 (moVlOO mol);
For hydrogen sulfide a range between 0,1 (rnolJlOO 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.BS EN 15984 pdf download.
