天然气碳氢露点的测试理论、方法及溯源

MEASUREMENT OF NATURAL GAS HYDROCARBON DEW POINT: PRINCIPLES, METHODS AND ORIGIN

天然气能源体系中扮演着越来越重要的角色,人们对天然气性能的认识也在不断加深。其中天然气的碳氢露点对天然气的质量、运输、买卖双方的利益等有着重大的影响,因此受到越来多的关注。在本文将从天然气的组成、碳氢露点的定义及影响因素、测试理论及方法、测试仪器的校准等方面进行阐述。

The position of natural gas in the system of energy sources becomes increasingly important, and the understanding of its properties is ever expanded. The hydrocarbon dew point calls attention for it affects natural gas quality, transport and interests of both its buyer and its seller. This paper expounds how to achieve the hydrocarbon dew point determination by analyzing the composition of natural gas, the definition of hydrocarbon dew point, its affecting factors, measurement principles, methods and instrument calibration.
