Hydrogen Sulfide Measurement With Wireless Technology

Fig. 1—Point-to-point decision tree.

Hydrogen sulfide (H2S) represents a major hazard in oil and gas production, and the efficient and reliable detection of gas leaks is a critical safety aspect. Wireless-detection systems offer an opportunity to expand the measurement area. This paper reviews a specific application of wireless technology in gas detection and details the steps taken to assess the integrity of the wireless system and the considerations necessary to ensure the reliability and availability of the signal transmission.

Wireless-Sensor Networks (WSNs)

WSNs are an alternative to hard-wired systems where the cabling is replaced by radio-frequency (RF) transmission of the measured data into a host system. The network may be point-to-point or meshed transmission. Meshed transmission allows for multiple alternative routes and, therefore, offers potential improvements in the ability of the system to ensure that the data are delivered to the host system.

WSNs have been developed since 2003 on the basis of Institute of Electrical and Electronics Engineers (IEEE) Standard 802.15.4, which defines the operating frequency of 2.4 GHz and other aspects of the basic physical layer of communication. This is currently adopted by the process industry as the essential foundation for most wireless-measurement systems.
