Workers in the oil & gas industry encounter a range of dangers in inherently risky environments. In particular, they are at risk of exposure to dangerous gases. Most common of these gases is hydrogen sulphide (H2S). H2S is a colourless gas, known by its characteristic rotten egg-like odour. Because it is a naturally occurring gas contained in many of the world’s crude oils, it can be found in almost every aspect of the oil & gas production process. Every step, from exploration and drilling to refining, demands personal monitoring of this deadly gas.
Another dangerous gas often present in the oil & gas industry environments is sulphur dioxide (SO2). This also is a colourless gas with a characteristic, irritating, pungent odour. In low concentrations, SO2 can cause burning of the eyes, nose and respiratory tract, and high concentrations can cause death quite rapidly. This gas is released when burning fossil fuels, so processes that contain fuel-fired furnaces, FCC units, sulphur recovery units and flaring operations can produce high concentrations of sulphur dioxide.
The new Tango® TX1 single gas monitor with DualSense™ Technology can detect H2S or SO2 as well as carbon monoxide (CO), or nitrogen dioxide (NO2). The development of the Tango was motivated by a study of more than 2.2 million iNet® data points and 25 000 gas detectors used in the field over a two-year period, which revealed the inability of many gas detection users to bump test their instruments adequately.
The Tango uses two identical sensors to detect the same gas. The two readings are processed through a proprietary algorithm and displayed as a single reading to the user. Workers in the oil & gas industry wearing the Tango are 85 times safer than they would be using any other single gas monitor available today, regardless of bump test frequency. With the sensor redundancy of DualSense Technology, users of the Tango do not have to worry whether or not the gas detector will keep them safe in the field.
The Tango is powered by one replaceable 2/3 AA lithium battery that will power it continuously for three years, even if the instrument is being used in the optional ‘always on’ mode. When the battery can no longer support instrument operations, it can be easily replaced to enable another three years of continuous operation. With a three-year instrument warranty, three-year CO and H2S sensor warranty, and two-year SO2 and NO2 sensor warranty, the Tango is reportedly the most cost-effective instrument of its kind available.
