The determination of water vapor (and water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to freezing and corrosion of plant and equipment. There are a number of ways of determining the water vapor concentration in natural gas, including the use of advanced, near-infrared tuneable diode laser absorption spectrometers (TDLAS).
This paper will discuss AMETEK’s experience with water vapor measurements in natural gas applications and highlight the development of their laser-based instruments for the measurement of water vapor in stationary and portable applications in the natural gas and LNG industry.
