  • Page 13: Chapter 1. Features And Capabilities

    Features and Capabilities Overview BH’s Aurora H2O Moisture Analyzer for Natural Gas makes it possible for natural gas processing and transportation facilities to monitor moisture content in real-time with high precision and reliability. The Aurora H2O analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to measure moisture in natural gas at the speed of light.

  • Page 14: Theory Of Operation

    As the concentration of water increases, the absorption also increases. The Aurora H2O sweeps the diode laser output across a narrow band in the near infrared spectrum and, by measuring the light intensity with a photodetector, is able to provide a direct indication of the partial pressure of water.
  • Page 15 The diode laser emits low energy light, and therefore the system will not ignite the gas. The complete system is rated explosion-proof, and the Aurora H2O provides very fast response time. Once the absorption cell (see Figure 1 below) is purged, the response time is a matter of a few seconds.

    Verifying Aurora H2O Performance in the Field There are two methods for verifying the performance of the Aurora H2O in the field. The first method is to use a portable hygrometer such as BH's PM880 portable hygrometer. The second method is to use a moisture generator or standard gas cylinder.

  • Page 138: Using A Moisture Standard

    Whether using a moisture generator or a standard moisture gas cylinder, the source gas should be connected to the Aurora H2O using the PURGE INLET on the analyzer. Ensure that the sample gas pressure is regulated to a just barely positive pressure and establish gas flow from the PURGE INLET to the Aurora H2O measurement cell.
