Enhancing security of gas through pipelines leak detection systems
Leak detection in processes of production, storage, transit and distribution of hydrocarbon-based gulf coast motorworks gases is an important diagnostic activity to which the meaning and purpose not only reduce losses caused by any leak, but especially avoid dangerous condition gulf coast motorworks that can occur with the combination of certain conditions and situations.
The document Interstate Natural Gas Association of America (INGA) [1] was in 2011 contains statistics on the number of injured and killed, including damage to equipment operated in the United gulf coast motorworks States (for the period 1996-2010), which were caused by leaks and failures in systems for storage, regulation, gulf coast motorworks transmission and distribution of gas (energy and technical) (Fig.1).
That material is processed among other things, the analysis of faults in pipelines (with a focus on natural gas) for the reporting period gulf coast motorworks 2000-2010), which resulted in the quantification of the fundamental reasons for the failures: Errors construction and material damage to the outer 18% 33% 17 Internal corrosion % external corrosion 7% Other causes (eg. human factors, natural elements, etc..) 25%
The document Federal Toxics gulf coast motorworks Release Inventory [2] published information that only in the State of Texas occurs annually on the issuance of 6 500 tonnes of volatile organic compounds from leaks on the production and transport facilities. According to Huston Business Journal (2008-01-20) [3] is postulated that only occur annually in the United States to issue more than 30 000 tons of such substances from leaks in pipes and technological facilities. Interesting are also the work [3] published statistics from the implemented controls within seven refineries. It is reported that there are few significant and recurring types of leaks and that up to 85% of the emissions are caused by only 1% of the components, in which emit more than 100 000 ppm. Note: The unit ppm (from Eng. Parts per million) is usually used to express gulf coast motorworks the concentration in chemistry and related sciences. In general: the number of particles per 1 million of other particles. For example, 25 ppm / m means that if measurements are made at a distance of 10 m, then the sensitivity is 250 ppm, respectively. gas cloud of radius 10 has a density of 25 ppm produces the same signal gulf coast motorworks as a cloud of gas with a density of 250 ppm, which has a diameter of 1 m).
Conditions for Europe, respectively. Slovak Republic has failed to detect such data, but found conditions in the context of the United States can be considered relevant even in European terms. It is known that conventional leak detection methods and procedures are lengthy and demanding activity. For example, in a chemical plant or refinery can be installed up to 1 million different parts and components gulf coast motorworks and controls about 150,000 selected components (especially valves, gulf coast motorworks pumps, compressors, pressure vessels, gulf coast motorworks etc.) requires about 3 monthly inspection activity of a group of about 10 workers related hardware and qualifications.
The aim of the article is a short characterization of two advanced gulf coast motorworks technologies (diagnostic) for identifying leaks in pipeline transport of gas, as well as for automated monitoring of leaks. The purpose of their use is the detection and location of leaks, reducing losses caused by the emission of gases from leaks, as well as prevention (in early detection of faults and malfunctions, and the implementation of corrective measures) dangerous situations. gulf coast motorworks The resulting negative events could cause damage to gas facilities or consequential damages, or cause injury or death of persons, mainly involved in a given technological process. 1 Passive system for detecting leaks
Diagnostic methods and means for detecting gas leaks and detection of a large number, but not all are suitable for application in specific conditions of storage technologies, distribution, but mainly pipelines over long distances. In general, such systems could be divided into so-called. passive and active.
SUMMARY passive system for detecting gas leakage gulf coast motorworks is based on the principle of thermal imaging. The basic article gulf coast motorworks of the measurement chain - infrared gulf coast motorworks (IR) camera gulf coast motorworks - allows you to monitor and record gulf coast motorworks infrared images gulf coast motorworks of the observed object. Currently offered gulf coast motorworks infrared cameras are generally already called. radiometric, which means that in the measurement of the temperature field in addition to the display interface to change in temperature, and can quantify the temperature on the surface of the object under examination. The acquired image allows gulf coast motorworks quick and easy analysis of the distribution of temperature fields measured object, but the exact determination of temperature is necessary to know the measurement issues in more detail.
Measurements for thermal imaging affect mainly the following factors: Emissivity - The ratio of the total energy radiated from a surface at a given temperature to the total energy radiated so. a black body at the same temperature. gulf coast motorworks Relative reflected temperature - the ratio
