The invention relates to a natural gas station yard analysis cabin on-line analysis instrument installation distance design method. The method comprises: (A) collecting basic parameters of an on-lineanalysis instrument; (B) calculating blasting energy of all instruments according to the collected data, converting the blasting energy into TNT equivalent values, and selecting the instrument with ahigher value as a layout basis; (C) fitting the relationship between the correlation failure probability and the equivalent distance by combining a Gaussian distribution function probability model onthe basis of shock wave overpressure generated by explosion of 1,000 kg of TNT explosives, selecting an acceptable correlation failure probability, and qualitatively determining the equivalent distance; (D) calculating the safety distance of the selected instrument by combining the calculation results of the step (B) and the step (C) on the basis of the principle of shock wave overpressure equality; and (E) designing or adjusting the layout between the online analytical instruments according to the calculation result of the step (D). The calculated safety distance of the online analytical instrument provides guidance for installation and layout of the instrument, and provides guarantee for safe operation of an analytical cabin.
Description
technical field [0001] The invention relates to the field of on-line analysis technology and safety assurance technology of natural gas stations, in particular to a method for designing the installation distance of online analysis instruments in an analysis cabin of a natural gas station. Background technique [0002] In the natural gas industry, on-line analytical instruments are usually installed on the source fluid site for automatic measurement and analysis of natural gas components or physical parameters, and are widely used in natural gas production, purification, storage and transportation, trade and other links. The first station, intermediate station and terminal station of long-distance natural gas pipelines are generally equipped with three analytical instruments such as hydrogen sulfide, trace water, and chromatographic analyzer, and some first stations of gas transmission are also equipped with online hydrocarbon dew point analyzers. The analysis results of onli...
