Abstract

The invention relates to the field of natural gas calorific value measurement, and especially relates to portable conventional natural gas calorific value measurement equipment and a measurement method. A top cover for opening or closing a top opening is arranged on an integrated box, the first end of a test tube extends from the side wall of the integrated box and then is communicated with a four-way valve, the second end of the test tube is positioned outside the integrated box, the four-way valve is communicated with a gas inlet of the laser Raman spectrometer through a pipeline, the four-way valve is further communicated with a standard gas storage bottle through a pipeline, the pipeline between the four-way valve and the standard gas storage bottle is provided with a third stop valve,and the laser Raman spectrometer is electrically connected with a portable computer. According to the invention, the test tube extending out of the side wall of the integrated box is communicated with the natural gas pipeline, so that natural gas can be effectively measured. The integrated box is convenient to move and carry, and the technical problem that no portable commercialized equipment isavailable for measuring the conventional natural gas calorific value is solved.

Description

technical field [0001] The application relates to the field of measurement of natural gas calorific value, in particular to a portable conventional natural gas calorific value measurement device and its measurement method. Background technique [0002] Methods for measuring the calorific value of natural gas include calorimeter direct measurement method, component indirect measurement method and correlation method. The direct measurement method of calorimeter has strict requirements on environmental conditions, complex operation process, easy to be interfered by human factors, difficult to calibrate the equipment accurately and standardizedly, and the purchase cost is high, so its application is relatively limited. Correlation technology is used to measure the relationship between natural gas calorific value and its associated physical properties, which is still in the research stage and has not yet matured. The component indirect measurement method is mainly a kind of qual...
