17、532:2017ISO 14532:2014(E/F)ForewordISO (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. Each member body interested
18、in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commi
19、ssion (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents sh
20、ould be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for
21、identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

24、 Natural Gas was established in May, 1989, with the task of creating new standards and updating existing standards relevant to natural gas. This includes gas analysis, direct measurement of properties, quality designation, and traceability.In these activities, a comprehensive and uniform review of t
25、he definitions, symbols, and abbreviations used in the standards was not previously systematically pursued. The development of standards with terminology created to suit specific purposes often resulted in the detriment of uniformity and cohesiveness between standards.Thus, there is the need for a w
26、ork of harmonization of the terminology used in the standards pertaining to natural gas. The intention of this International Standard is to incorporate the reviewed definitions into the ISO/TC 193 source International Standard.As the aim is to create a coherent body of standards which support each o
27、ther with regard to their definitions, common and unambiguous terms and definitions used throughout all International Standards is the starting point for the understanding and application of every International Standard.The presentation of this International Standard has been arranged to facilitate
28、its use as follows: Major headings pertain to specific fields of the natural gas industry. All definitions that fall under these headings, as gleaned from ISO International Standards issued through ISO/TC 193, are listed under that heading. A review of the contents will serve to facilitate finding s
29、pecific terms. Notes are given under numerous definitions where it was deemed important to give informative guidance for a given definition. The Notes are not considered a part of the definition.

30、abulary1 ScopeThis International Standard establishes the terms, definitions, symbols, and abbreviations used in the field of natural gas.The terms and definitions have been reviewed and studied in order to cover all aspects of any particular term with input from other sources such as European Stand
31、ards from CEN (The European Committee for Standardization), national standards, and existing definitions in the IGU Dictionary of the Gas Industry.The definitive intention of this document is to incorporate the reviewed definitions into the ISO/TC 193 source standards.2 Terms and definitionsFor the
32、purposes of this document, the following terms and definitions apply.2.1 General conditions2.1.1 Natural gas2.1.1.1natural gas NGcomplex gaseous mixture of hydrocarbons, primarily methane, but generally includes ethane, propane and higher hydrocarbons, and some non-combustible gases such as nitrogen
33、 and carbon dioxideNote 1 to entry: Natural gas can also contain components or containments such as sulfur compounds and/or other chemical species.2.1.1.2raw gasunprocessed gas taken from well heads, through gathering lines, to processing or treating facilitiesNote 1 to entry: Raw gas can also be pa
34、rtially processed well-head gas,taken from basic upstream processing facilities.2.1.1.3substitute natural gasSNGgas from non-fossil origin which is interchangeable in its properties with natural gas2.1.1.4manufactured gassynthetic gasgas which has been treated and can contain components that are not
35、 typical of natural gasNote 1 to entry: Manufactured (synthetic) gases can contain substantial amounts of chemical species that are not typical of natural gases or common species found in atypical proportions as in the case of wet and sour gases.Note 2 to entry: Manufactured gases fall into two dist
36、inct categories, as follows:a) those that are intended as synthetic or substitute natural gases, and that closely match true natural gases in both composition and properties;INTERNATIONAL STANDARD ISO 14532:2014(E/F) ISO 2014 All rights reserved/Tous droits rservs 1BS EN ISO 14532:2017ISO 14532:2014
37、(E/F)b) those that, whether or not intended to replace or enhance natural gas in service, do not closely match natural gases in composition.Case b) includes gases such as town gas, coke oven gas (undiluted), and LPG/air mixtures. None of which is compositionally similar to a true natural gas (even t
38、hough, in the latter case, it can be operationally interchangeable with natural gas).2.1.1.5lean gasnatural gas having a relatively low energy content, close to or lower than that of pure methaneNote 1 to entry: Lean gas typically contains high amounts of nitrogen and carbon dioxide.2.1.1.6rich gasn
39、atural gas having a relatively high energy content, higher than that of pure methaneNote 1 to entry: Rich gas typically contains high amounts of ethane or propane or higher.2.1.1.7wet gasgas which falls short of qualifying as pipeline quality natural gas by the inclusion of undesirable components su
40、ch as free water, water vapour and/or high hydrocarbons in such amounts that they can condense at pipeline conditions2.1.1.8sour gasgas containing significant amount of acid gases such as carbon dioxide and sulphur compoundsNote 1 to entry: The presence of acid compounds is more detrimental in wet g
41、ases.Note 2 to entry: Typically, wet and sour gases can be unprocessed (well head) or partially-processed natural gases and can also contain condensed hydrocarbons, traces of carbonyl sulphide, and process fluid vapours such as methanol or glycols.Note 3 to entry: Carbon dioxide in the presence of f
42、ree water can be an important cause of corrosion damage to pipelines.2.1.1.9dry natural gasnatural gas containing a mole fraction of water of no more than 0,005 % 50 ppm (molar) in the vapour phaseNote 1 to entry: Water vapour content in natural gas can also be expressed in terms of water concentrat
43、ion (mg/m3).Note 2 to entry: The correlation between water content and water dew point is given in ISO 18453.172.1.1.10saturated gasnatural gas that at the specified conditions of temperature and pressure is at its water dew-point2.1.1.11compressed natural gasCNGnatural gas that has been compressed
