 ForewordThis standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 13609-2012 Natural Gas Sampling Guidelines.
Compared with GB/T 13609-2012, the main technical changes in this standard are as follows.
---In the scope of the increase of "multi-source mixing, the gas should be mixed after sampling;"
--- In the 8.1 sampling probe c), the.2012 version of the "recommended probe position was removed at least 20 times downstream of the choke element.
Baffle elements include recommendations for elbows, headers, valves, T-tubes, etc.. Deleted.2012 version "Sampling probes should be inserted straight
1/3 of the diameter of the description was added to an informative appendix, “Sampling Probe Installation Locations and Tests,” and successively modified
The number of the appendix.
This standard uses the redrafted method to amend ISO 10715.1997 "Natural Gas Sampling Guidelines."
The technical differences between this standard and ISO 10715.1997 and its causes are as follows.
--- Added "CNG pressure up to 30 MPa in the range, which can be used to ensure the safety of the sampling system.
Use this standard" to increase operability.
---In the scope of the increase of "multi gas source mixed, you need to pay attention to sampling after the gas is evenly mixed," the sampling of multiple gas source mixed transmission
Tips to adapt to our technical conditions.
--- In the 8.1 sampling probe c), delete the "Recommended probe position at least 20 times the diameter of the downstream of the baffle element, the baffle element
Including bends, manifolds, valves, and T-tubes, etc. "Recommendations for sampling probes should be inserted in 1/3 of the diameter of the tube."
An informative appendix "Location and installation of sampling probes", and successively revised the number of each appendix;
Part of the test and the test results are given in the appendix.
--- Added "8.9 gas sampling bags" to increase operability.
--- Added "9.7 Insulation, Pressure Maintenance Sampling Method" and a normative appendix "Sampling Procedures for Insulation and Pressure Keeping Sampling Methods" to increase the number of operations
For sex.
This standard has made the following editorial changes.
--- Deleted "ISO 10715.1997 Appendix J References".
This standard was proposed by China National Petroleum Corporation.
This standard is under the jurisdiction of the National Natural Gas Standardization Technical Committee (SAC/TC244).
This standard was drafted by. PetroChina Southwest Oil & Gas Field Branch Natural Gas Research Institute, PetroChina Beijing Huayou Natural Gas Co., Ltd.
the company.
The main drafters of this standard. Tang Meng, Zhou Li, Li Ke, Zeng Wenping, Cai Li, Luo Qin, Chen Yong, Chi Yongjie, Li Guohai, Chang Honggang, Han Hui.
The previous version of the standard replaced by this standard.
--- GB/T 13609-1992, GB/T 13609-1999 and GB/T 13609-2012.
Natural Gas Sampling Guidelines
Warning --- Use of this standard may involve hazardous materials, processes and equipment. This standard does not mean that the accompanying standard
All safety issues brought about by the quasi-use. Users of this standard are responsible for establishing appropriate safety and health measures and clarifying them before use
Application restrictions or regulatory restrictions.1 ScopeThis standard establishes guidelines related to various aspects of natural gas sampling that have been processed. Unless otherwise specified, all pressures in this standard are
Given by gauge pressure, the pressure can be as high as 15 MPa. Compressed natural gas (CNG) pressures up to 30 MPa to ensure the safety of the sampling system
Next, this standard can be used.
This standard does not apply to the sampling of liquid or multiphase fluids. When multiple gas sources are mixed, it is necessary to take care that the samples are mixed after the gas is mixed.
This standard covers point sampling, combined sampling (accumulated sampling) and continuous sampling systems.
This standard considers components such as oxygen, hydrogen sulfide, air, nitrogen, and carbon dioxide in the gas stream.
If traces of liquids, such as glycols and compressor oils, are seen as interfering impurities, not as part of the sampled gas, they should be divided
Go to protect the sampling and analysis equipment from being contaminated.
This standard applies to delivery metering systems and transmission and distribution metering systems.
This standard applies to those situations where the sampling is not described as an analytical step. This standard focuses on the sampling system and steps
Step. The analysis of samples obtained using these systems and procedures can be used in many ways, including calculations to determine the amount of heat generated by the gas flow, and the identification of gases.
The presence of pollutants in the flow, from the composition of the situation to determine whether the air flow meets the contract specifications.2 Terms and definitionsThe following terms and definitions apply to this document.
2.1
Direct sampling directsampling
Sampling where the sampling medium is directly connected to the analysis unit.
2.2
Mobile piston cylinder floating-pistoncylinder
A container with a removable piston inside it is used to isolate the sample and the buffer gas. The pressure on both sides of the piston is balanced.
2.3
Flow ratio cumulative sampler flow-proportionalincrementalsample
At a certain time interval, the sampler is sampled at a rate that is directly proportional to the airflow of the gas source duct.
2.4
High pressure natural gas high-pressure naturalgas
Refers to natural gas with a gas pressure of 0.2 MPa or more.
2.5
Hydrocarbon dew point
At a given pressure, the temperature at which hydrocarbon vapors begin to condense.
2.6
Accumulative sampler incrementalsampler
Collect a series of samplers and collect them into a sampler.
