Method of Measurement and Computing for Natural Gas Energy

Abstract:

Energy measurement and computing can directly reflect the value of natural gas. In our country the volume flow measurement and computing will be gradually replaced by energy measurement. In this paper the principle of energy metering of natural gas is introduced and the system of energy metering of natural gas is constructed. Based on GB/T 11062, computing method of gas energy is discussed, in which quality data of natural gas, temperature, flow, pressure parameters are measured by energy metering system and the calorific value of natural gas, relative density and Wobbe index are and computed. Also the uncertainty of and computing method for natural gas energy is analyzed in which uncertainty is within 0.1%. The results show that the uncertainty of the calorific value measurement system attained accuracy requirements of GB/T 18603-2001.
