What Are The Causes of Negative Transmission Difference of Natural Gas?

Analysis of the Reasons for Negative Gas Transmission Differences in Natural Gas Transportation

As a clean energy source, natural gas has always been widely concerned about the transmission and distribution issues that arise during its transmission and distribution process. The situation of negative transmission difference, that is, the actual gas transmission volume is greater than the gas transmission volume measured by the meter, has sparked in-depth discussion in the industry. This article will focus on analyzing the reasons for negative natural gas transmission differences.

Firstly, we need to clarify that the measurement of natural gas is a rather complex process that involves multiple factors, such as the physical properties of the gas, environmental factors, and errors in the measuring equipment itself. This provides a possibility for the occurrence of negative transmission differences.

1、 Physical property influence

The physical properties of natural gas, such as density, pressure, temperature, etc., can affect the measurement results. Especially the influence of temperature, due to the compressibility of gases, temperature changes can lead to significant changes in gas volume, thereby affecting measurement accuracy. In addition, the flow state of gas in pipelines may also affect the measurement results. Turbulence, vortices, and other flow states may cause the actual volume of gas passing through the measurement equipment to be greater than the theoretical value.

2、 Environmental factors impact

Environmental factors such as atmospheric pressure, humidity, wind speed, etc. may also have an impact on natural gas metering. For example, in areas with lower atmospheric pressure, due to gas expansion, the actual volume of natural gas passing through metering equipment may increase, leading to negative transmission differences.

3、 Measurement equipment error

The error of measuring equipment is an important reason for the negative transmission difference. The aging, wear, or improper use of equipment may lead to deviations in measurement results. In addition, the accuracy issue of measuring equipment itself is also an undeniable factor.

4、 Human error in operation

Human error is also a common cause of negative transmission differences. For example, in the case of switching gas sources or handling large amounts of gas, operators may neglect or operate improperly, resulting in inaccurate readings of measuring equipment that reflect the actual situation.

In summary, the reasons for negative natural gas transmission differences are multifaceted, including the influence of physical properties and environmental factors, as well as factors such as measurement equipment errors and human operational errors. In order to reduce the occurrence of negative transmission differences, we need to improve and optimize in multiple aspects. Firstly, improving the accuracy and stability of measuring equipment is crucial. The use of high-precision and highly stable measuring equipment can effectively reduce errors. Secondly, strengthening the maintenance and upkeep of equipment is also a necessary measure. Regular inspection and maintenance of equipment can ensure its normal operation and service life. In addition, improving the skills and qualities of operators is also one of the important measures. Training and assessment can improve the skill level and work responsibility of operators, thereby reducing the occurrence of human operational errors. Finally, strengthening supervision and management is also one of the necessary measures. By establishing a sound regulatory mechanism and management system, the correct use and operation of equipment can be ensured, thereby reducing the occurrence of negative transmission differences.
