Оnushko V. Method and Optical-Electronic Device of Measuring Control of Humidity of Natural Gas

The object of research is the process of measuring moisture control natural gas intention is to increase the probability of measuring humidity control gas on the basis of differences in the properties of absorbing infrared radiation passing through the dry gas and water vapor; methods are based on a theory of light propagation in gas environments, theory humidity substances, methods of physical and mathematical modeling, theory of measurement, control and error, stochastic processes, methods of mathematical statistics in the processing of results, methods of metrological certification and verification of non-standardized measurement tools, theoretical results - further developed a method of measuring humidity control natural gas in the infrared region and developed Dual diagram for its implementation, which helped reduce the number of controlled parameters (pressure wet gas, dry gas molar mass), which is characterized in that the humidity value of gas obtained from the ratio of the absorption of natural dry gas and water vapor; improved mathematical model of radiation transfer in a wet gas environment that adequately describes the physical processes improved mathematical model of two-channel infrared moisture measuring transducer on the basis of feedback, which takes into account the parameters of the light source. Practical results - designed and implemented an experimental model of opto-electronic moisture analyzer, wherein that increase the probability of control properties accounted absorbing certain wavelengths of both dry gas and water vapor by passing through gas environment for linearization of the output characteristics used feedback; experimentally investigated the laws of distribution of controlled variables and measurement error, it is proved that these laws are normal; established that provides a means of controlling the likelihood moisture control natural gas within 0,97-0,98, the method of experimental determination of specific molar absorption indices dry natural gas and water vapor, as well as experimental selection of the wavelength of the radiation source for dry gas and water vapor. Degree of implementation - the results of the thesis introduced in "IZODROM" Kyiv and the learning process of the Department of Electronics NTB. Scope (industry) use - transportation sector domestic gas and residential areas.
