- 12. Gas Detection Hazards
12
3 main types:
Toxic
Units: Parts Per Million (PPM - PPB)
e.g., Hydrogen sulfide, Carbon monoxide, Chlorine
Combustible
Units: % Lower Explosive Limit (LEL)
e.g., Methane, Propane, Butane
Asphyxiate
Oxygen deficiency
- 13. Why Hydrogen Sulfide (H2S)?
H2S IS EXTREMELY POISONOUS AND EXPLOSIVE
1. Fatal in high concentrations
2. Biggest risk in upstream O&G and refining
3. Causes 1/3 of all fatalities
4. Soluble in liquids like oil
5. Expands when reaching atmosphere
6. Colorless, smells like rotten eggs, can’t smell in
high concentrations (100 PPM)
- 14. Why Methane (CH4)?
METHANE (CH4) CLOUD IS EXTREMELY EXPLOSIVE
Hi pressure natural gas leaks
expand into a cloud and explodes when
it reaches an ignition source

Toxic and Combustible gas detection
- Simple 4-part agenda
Combining wireless with gas detectors
Explore customer problems uncovered by our market research
Co-presenter Wil Chin will provide some solutions to those problems
And finally, we’ll share the best practices for wireless gas detection
- Title slide
- Portable detectors are battery powered, carried by plant personnel. Pocket-sized and can detect several different gases
Fixed detectors are single gas devices installed in permanent installations similar to other field devices - like pressure transmitters
Point detectors are placed where gas emissions are most likely to occur. Gas must come into contact with the device’s sensor to be detected.
Open path detectors cover a wider area but may be less effective in protecting specific areas. Gas concentrations can vary depending on the weather
Ultrasonic detectors (are the most expensive and) detect high pressure gas leaks by sensing the ultrasonic "noise" generated by the leak. These detectors do not measure gas concentrations but may determine the volume of the leak.
Portable/Personal - 65%
Fixed -35%
-Point - 85%
-Ultrasonic - 12%
-Open Path - 3%
This presentation is for Fixed Point gas detectors
-
Only fixed point detectors are available in a wireless configuration. We’ll concentrate on Fixed Point gas detectors for this presentation
- Wireless plays a large role in gas detection by providing more freedom on where the detectors are located, or placed.
Methane gas will rise and collect at the highest point. This is typical of the ceiling of a garage where CNG vehicles are operated and refueled, for example. Methane will collect there so it’s necessary to mount the gas detector high in the ceiling of these facilities.
Hydrogen sulfide, on the other hand, is heavier than air and will tend to collect at the lowest point. Wells and vaults are known to collect H2S so detecting gas from inside these areas is essential for maximum safety.
Common to both of these areas is the lack of power and wiring for field instrumentation to transmit their signals to a monitoring control station, thus the need for wireless.
- Here are some numbers to consider:
Approximately 40M HART devices currently installed
More than 26K WiHART networks currently operating worldwide
Commercial and residential wireless sensors are growing at a rate of almost 28% annually
More than 50 different WiHART products are currently available
Network reliability has dramatically increased to better than 99%
The other leading process industry wireless standard is ISA100.
There are only a few suppliers of ISA100 with limited adoption compared to over 26,000 WirelessHART networks and over 50 suppliers of WirelessHART devices
- Characteristics of self-organizing mesh networks:
Read the bullet points on the slide and elaborate
Talk about the red circle and how it indicates a stationary or moving/mobile obstruction and how the gateway deals with it.
Any WirelessHART device – P, T, Flow, Level, Gas detection functions, brands, etc.
To add a device to the network, use a field communicator to provide the gateway network ID and the join key.
The gateway will then detect the device, add it to the network
The gateway automatically optimizes the wireless network connections for obstructions, distance and signal strength
- Why WirelessHart? Interoptibility!
Interoperable = works with any WiHART compatible device!
The map here shows a wide variety of devices from several different manufacturers all coexisting together on the same wireless network.
This topology map shows the physical location of the wireless field instruments and shows how the network is formed to connect each device to the gateway.
Maps like this provide a graphical representation of the network and can be used to adjust device locations in order to minimize obstructions.
The red circle shows the location of the UE Vanguard gas detector relative to other devices in the network and the signal paths to the gateway.
Many suppliers, typical map, shows interoperability.
- In heavily obstructed areas, signal distance may be affected
4 levels from heavily obstructed to clear line of site
800 feet is the recommended maximum distance between field instruments with clear line of sight
The field instruments use each other to help communicate with the gateway
Frequency hopping provides:
Primarily: optimization for traffic and
Secondarily: security
ISA100 networks or topologies can provide larger distances but are better suited for star topologies
- For those that considered wireless in the past, the technology has changed to increase reliability while reducing complexity.
Open protocols, such as WirelessHART, promote more instrument types and vendor participation
WirelessHART gas detectors, for example, can coexist to augment and compliment wired gas detectors; not intended to replace
WiHART is a cost-effective way to increase coverage in areas of the plant that are difficult to reach
Additional sensors are easily added to existing (Pressure, Temp, Flow, Level) wireless networks
Wireless provides an instant monitoring solution, especially for brownfield facilities
Battery life with the UE Vanguard gas detector is guaranteed for 5 years
- Now I want to discuss 3 main gas detection categories: Toxic, Combustible, and Asphyxiate
Toxic gases:
Units of measure: PPM and PPB
Examples of Toxic gases are hydrogen sulfide (H2S), carbon monoxide and chlorine
Combustible gases:
Are measured in % lower explosive limit (LEL)
Examples of combustible gases are methane (CH4), propane and butane
Asphyyxiate gases create an oxygen deficient atmosphere by depleting the oxygen
These gases are all common in hydrocarbon processing operations.
- Read the slide
3. All refining fatalities
- A methane cloud is very explosive (volatile)
For ignition to occur, 3 things are required:
A fuel source
oxygen
and an ignition source
Our research for O&G toxic and combustible gas processing cited methane and hydrogen sulfide (H2S) making up more than 80% of the gases present.
Visit YouTube for some examples of methane gas accidents
- Next, we would like to share some of our market research used to uncover pervasive problems with our customers.
- Our market research over the past few years has uncovered several pervasive customer problems:, our customers have told us about:
How it is Costly and labor intensive to install wired GD
Current Infrastructure can’t support additional devices
Installing wired fixed detectors can take months (retrenching)
Proprietary wireless is too costly to install & maintain
Unavailability of line power in remote areas
NEXT SLIDE
Portable personal detectors not accurate - provide limited safety
Local alarms not visible to control room
Insufficient gas detection coverage – accidents
Can’t detect emissions leaks from pipes and infrastructure
Insufficient resources for maintenance
- Our customers also told us:
Portable personal detectors are not accurate - provide limited safety
Local alarms are not visible in the control room
Insufficient gas detection coverage leads to accidents
Customers Can’t detect emissions leaks from pipes and infrastructure
They’re dealing with Insufficient resources for maintenance
- UE Research conservative view
This graph shows a very conservative estimate of open wireless network GD growth if customer problems can be resolved!
Growth rate of proprietary wireless gas detectors is twice, double, 2X that of wired gas detectors
We expect growth of open WirelessHart gas detectors will grow at a CAGR of 30%

-place anywhere without any physical constraints
-
One WirelessHart gas detector was Co-developed with Chevron for predictive maintenance to reduce inspection rounds by identifing leaks
Appropriate for equipment such as Pipes, valves, tanks, seals, pumps, compressors
Increase productivity by improving process uptime, reducing unplanned downtime while improving safety
By Triggering inspection and mitigation of a problem before it becomes dangerous…
- Most remote sites have little to no wired infrastructure.
Adding conduit for power and signal requires design, trenching, and testing and can negatively affect project schedules
End user selected WI-HART because of long distance from controller, limited wiring infrastructure, availability of an existing Wi-HART network
- Adding new gas measurement points in an existing facility is inconvenient, time consuming and very costly, particularly when the signal crosses a street of a bridge.
The WirelessHART gas detectors can be plugged-and-played anywhere in an existing WirelessHART mesh.
The end user wanted fixed point gas detectors to complement personal detectors and warn workers from entering a dangerous space
They had power & Wi-Hart but far from control room thus selected the Vanguard WirelessHart gas detector
- The production of coke produces numerous hazardous by-products such as toxic hydrogen sulfide (H2S). As we know, H2S is lethal effect even in minute concentrations.
Customer needed to run 24 x7, lacked GD coverage, concerned about H2S wire corrosion and had a Wi-HART network
WirelessHART GD provided a quick, cost effective additional layer of personnel protection against toxic H2S.
Devices can be easily deployed and interoperated with other WirelessHART devices in the existing network .
In this application Wireless was absolutely necessary as H2S corrodes wires!
- Adding wired detectors is costly, as much as $10,000 when you add the cost of redesign, obtaining ‘hot’ work permits, retrenching, running conduits for wires particularly in remote applications across various elevations .
Excellent applications include monitoring tank farms, fence line locations
Wireless GD saves thousands in conduit, wire and labor
- Temporary worksites including: Process unit startups, shutdowns, Maintenance, and Inspection can be dangerous. Its been estimated that most accidents happen in startups and shutdowns for maintenance.
Work areas typically do not have GD in these areas as the presence of gases are not present during normal operation
Personal detectors are not sufficient as it only warns the worker when the worker is already in the area while fixed point GD can warn workers before they enter a closed spaces such tanks for cleaning
Wireless GD allows the deployment around the perimeter of work sites and inside closed spaces when & where needed
- A massive natural gas leak that was discovered on Oct 23, 2015; plugged on Feb 18, 2016, but recently leaked again
The resulting evacuations and sick residents spawned lawsuits and calls for tighter regulations
- Once a natural gas field, this Central Valley Gas converted the field into a storage reservoir through gas reinjection. These wells could be a source of methane gas leakages.
With the looming methane emissions rule, Central Valley wanted to take proactive steps to develop a cost effective way of measuring leaks.
The lack of signal and power infrastructure precluded the use of wired gas detectors in this remote location.
With the help of optical imaging technology, the GD were optimally positioned on wellheads to detect a controlled release of a methane plume with wind conditions.
The Vanguard GD reliably detected the presence and absence of gas.
It also accurately reported the concentration of the passing methane plume which was verified by the optical imaging cameras.
