Despite the active development of power-oriented technologies and the most invested projects to transition to alternative energy sources, today global processes cannot be imagined without the use of electricity. use natural gas. Gas is one of the most valuable factors in the functioning of the global energy system, thus creating certain conditions that cause its price to fluctuate and provide a basis for speculation. However, it should be remembered that the subject of gas production is first and foremost involved in hazardous activities and therefore requires clear regulation by means of a number of documents, standards and rules. Today we will introduce you to the main international standards in the field of natural gas production.
Natural gas — Deodorization
ISO/TS 16922: 2022
Since the natural gas extraction process is exposed to a certain amount of toxic elements that can adversely affect human health, it is necessary to control this process and standardize according to international documents such as ISO/TS 16922: 2022. This document provides specifications and guidelines for the methods used in the odorization of natural gas and other methane-rich gases provided by the natural gas network for gas applications. burning from a safety perspective. This document also specifies the principles of odor engineering (including the handling and storage of odorants) and the control of odor generation of natural gas and other methane-rich gases.
NOTE General requirements for odorants and the physical and chemical properties of commonly used odorants are specified in ISO 13734. Since this international document contains only general requirements and standards, it is necessary to note that the maximum effectiveness of its application will only be achieved by combining it with similar international standards to create a comprehensive legal and regulatory complex of the business.
Natural gas — Gas chromatography requirements for the calculation of the dew point of hydrocarbons (ISO 23874:2006)
SIST EN ISO 23874:2018
The calculation of several indicators significantly affects the prediction of the final result, as well as the safety of the operation of the equipment in a particular area. Today, an international standard such as SIST EN ISO 23874:2018 is used for costing activities in the natural gas production industry. ISO 23874:2006 describes the performance requirements for the analysis of processed pipeline or pipeline-grade natural gas in sufficient detail that the dew point temperature of hydrocarbons can be calculated using Equation d. appropriate status.
ISO 23874:2006 can be applied to gases with maximum dew point temperatures (cricondentherms) between 0 °C and - 50 °C. The pressure at which these maximum dew temperatures are calculated ranges from 2 MPa (20 bar) to 5 MPa (50 bar). The procedure described in ISO 23874:2006 covers the measurement of hydrocarbons in the range C5 to C12. n-Pentane, measured quantitatively using ISO 6974 (all parts), was used as the bridging component and all hydrocarbons C6 and above were measured in terms of n-pentane.
Principal components are measured according to ISO 6974 (all parts) and the range of measurable components is as defined in ISO 6974-1. As key aspects of the regulations in this document overlap with several related industry standards, be aware that sometimes a single standard is not enough to ensure overall productivity and safety.
Natural gas powered vehicles - Vehicle refueling equipment
SIST EN 17278:2021
While most standards contain standards for more general categories, the importance of specific standards such as SIST EN 17278:2021 should not be overlooked. These international standards only govern part of the whole system, but they are still very important. This document deals with the design and manufacture, installation and testing, operation and maintenance of vehicle refueling units (VFAs) - pressure equipment sets with limited specifications. , used to refuel non-commercial natural gas vehicles (NGVs) with compressed air. natural gas (CNG).
This document applies to VFAs fueled with natural gas as defined in the applicable local regulations on gas composition or in EN 16723-2 or to other gases that meet the requirements. This requirement includes biomethane, coal-fired methane (CBM) and liquefied natural gas (LNG). ) vaporizers (on-site or off-site). In the case of a combination of a certified VFA set with additional equipment, such as an external storage and/or dispenser, EN ISO 16923 applies to a new set - certified VFA set with external equipment additional. Since this international document only deals with a certain type of equipment, its application can only be applied to a narrow industry.

Natural gas - Determination of energy (ISO 15112:2018)
EN ISO 15112:2018
The energy complex is one of the industries that uses a large number of devices and elements that can endanger life. This is why a large number of regulatory documents are being created, such as EN ISO 15112:2018. This document provides a means of determining the energy of natural gas by measurement or calculation, and describes the techniques and associated measurements to be performed. The calculation of thermal energy is based on a separate measurement of the quantity, by mass or by volume, of the gas being transferred and its measured or calculated calorific value. General means for calculating uncertainty are also given. Only systems currently in use are described. NOTE The use of such systems in commercial or official commerce may require the approval of national licensing authorities and compliance with regulatory requirements.
This document applies to all gas measurement stations from domestic to very high pressure transmission lines. New techniques are not excluded, provided their proven performance is equal to or better than the techniques mentioned herein. Since any change with significant impact must be regulated by the local government in the first place, we recommend that you carefully study the government's standards and requirements and compare the performance changes specified in international standards.
Why is it important for companies to follow international standards?
Since the energy sector is global and therefore has a number of widely accepted standards and rules, it is important to conduct global economic activity with confidence in compliance with all security measures. . This is only possible when the clear rules set forth in international standards are followed. Therefore, any company that is active in the gas production sector and has several scaling projects, or is already an important player in the international market, must comply with the standards. international standardization to be able to maintain its business. leading position. and climb a level higher and further.
