Challenge

Customer operates a coke manufacturing facility. The coke produced in the plant is transported to a steel mill. The coke manufacturing process results in numerous hazardous by-products such as toxic hydrogen sulfide (H2S). H2S needs to be monitored for personnel protection due to its lethal effect even in minute concentrations. Adding new gas measurement points in an existing facility can be inconvenient and very costly. Such costs includes obtaining ‘hot’ work permits, running conduits for wires across various elevations and can amount to about $10,000 per device.

Solution

Wireless gas detectors like the Vanguard can augment existing gas detection coverage with minimal financial and labor outlay. The Vanguard can be plugged-and-played anywhere in an existing WirelessHART mesh and perform its role as a first line of defense for H2S monitoring. The Vanguard provided a cost effective additional layer of personnel protection against toxic H2S. Devices can be easily deployed in locations known to emit H2S and also redeployed readily if needed. Vanguard was interoperable with other WirelessHART® devices, all of which was managed through an Emerson gateway.
