Natural gas - Determination of sulfur compounds - Part 5: Lingener combustion method (ISO 6326-5:1989)

Specifies a method for the determination of total sulphur in natural gas. It is applicable to gases with sulphur contents between 0,5 mg/m3 and 1 000 mg/m3. With a total sulphur content of more than 0,1 mg sulphur in the absorption solution, visual titration with an indicator can be chosen, whereas for lower contents turbidimetric titration is preferable.

Erdgas - Bestimmung von Schwefelverbindungen - Teil 5: Verbrennung nach dem Lingener-Verfahren (ISO 6326-5:1989)

Dieser Teil von ISO 6326 legt ein Verfahren für die Bestimmung des Gesamtschwefelgehaltes in Erdgas fest. Das Verfahren ist anwendbar auf Gase mit Schwefelgehalten zwischen 0,5 mg/m3 und 1000 mg/m3. Bei einem Gesamtschwefelgehalt von mehr als 0,1 mg in der Absorptionslösung kann die visuelle Titration mit einem Indikator gewählt werden, während bei niedrigeren Gehalten die Trübungstitration vorzuziehen ist.

Gaz naturel - Détermination des composés soufrés - Partie 5: Méthode de combustion Lingener (ISO 6326-5:1989)

La présente partie de l'ISO 6326 prescrit une méthode pour la détermination de la teneur totale en soufre du gaz naturel. Cette méthode est applicable aux gaz dont la teneur totale en soufre est comprise entre 0,5 mg/m3 et 1 000 mg/m3. Le titrage visuel avec indicateur peut être choisi lorsque la teneur totale en soufre est supérieure à 0,1 mg dans la solution absorbante, le titrage turbidimétrique étant préférable pour les teneurs inférieures. --
NOTE Dans toutes les parties de l'ISO 6326, 1 m3 de gaz est exprimé pour les conditions normales (0 °C; 101,325 kPa).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (1 EC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 6326-5 was prepared by Technical Committee ISO/TC 158,
Analysis of gases.

Introduction
The standardization of several methods for the determination of Sulfur compounds in
natura1 gas is necessary in view of the diversity of these compounds [hydrogen sulfide,
carbonyl sulfide, thiols (mercaptans), tetrahydrothiophene (THT), etc.] and the pur-
poses of the determinations (required accuracy, measurement at the drilling head or in
the transmission pipes, etc. ).
In Order to enable the user to choose the method most appropriate to his needs and to
perform the measurements under the best conditions, ISO 6326 has been prepared in
several Parts.
ISO 6326-1 gives a rapid comparison of standardized
methods and therefore provides
information for the choice of the method.
The other Parts of ISO 6326, including this Part, describe in detail the various stan-
dardized methods.
The determination of total Sulfur is specified in ISO 4260 : 1987, Petroleum products
and hydrocarbons - Determination of Sulfur content - Wickbold combustion
me thod.
