The Future of Combustible Gas Monitoring in Oil and Gas: PureAire Safety Solutions


 

Introduction

Safety is a top priority in the oil and gas industry, where the presence of flammable gases poses significant risks. Combustible Gas Monitors for the Oil and Gas Industry help maintain a safe environment for workers.

These combustible gas monitoring devices detect and warn personnel of the presence of dangerous gases, including methane, a commonly found gas in oil and gas operations.

Gas detectors provide real-time alerts, which allow for quick response actions to prevent accidents. Companies utilizing combustible gas monitors can proactively manage risks and protect their employees, facilities, and end products.

PureAire Monitoring Systems, an industry leader in gas monitoring safety solutions, works closely with this critical sector to provide innovative, reliable, and accurate gas detection systems. By utilizing innovative and advanced technology, PureAire’s line of LEL/Combustible Gas Detectors significantly enhances safety standards within the industry. This commitment protects personnel and supports operational efficiency by reducing downtime due to unexpected incidents.

Understanding Combustible Gases in the Oil and Gas Industry

Combustible gases are a significant concern within oil and gas refineries, posing potential hazards due to their flammability. Methane and hydrogen sulfide are among the most prevalent gases encountered in these environments.

Methane (CH4) is a colorless, odorless, highly flammable gas. It is often a significant component of natural gas. When mixed with air, methane can form explosive mixtures. Detecting methane at low levels of Lower Explosive Limits (LEL) is essential for preventing catastrophic events.

Hydrogen Sulfide (H2S) is a colorless gas known for its pungent “rotten egg” odor at low concentrations. However, according to the Occupational Safety and Health Administration, do not rely on your sense of smell to indicate hydrogen sulfide’s continuing presence or warn of harmful levels. You can smell the “rotten egg” odor of hydrogen sulfide at low concentrations in the air. But after a while, you lose the ability to smell the gas even though it is still present. This loss of smell can happen rapidly and at high concentrations, and a person’s ability to smell the gas can instantly be lost. Hydrogen Sulfide is extremely flammable and highly toxic.

When working with flammable gases, knowing the Lower Explosive Limit (LEL) is vital. LEL is the minimum concentration of flammable gas or vapor that will propagate flame when exposed to an ignition source.

Industry Standards

NFPA 70 Standards and Fire Safety

The National Fire Protection Association (NFPA) sets essential guidelines for fire safety, particularly through NFPA 72, which addresses key selection factors in Chapter 17. This chapter outlines crucial considerations for the placement and spacing of combustible gas monitors and fixed combustible gas detectors. An engineering evaluation must consider:

  1. The size of the fire to be detected
  2. Fuel involved
  3. Sensitivity of the detector
  4. Field of view (FOV) of the detector
  5. Distance between the fire and the detector
  6. Radiant energy absorption of the atmosphere
  7. Presence of extraneous sources of radiant emissions
  8. Purpose of the detection system
  9. Response time required

These parameters ensure that detectors are optimally positioned to monitor hazardous environments effectively.

Understanding and adhering to Federal, State, Local, and Industry standards is vital for maintaining safety in environments where combustible gases pose significant risks. These guidelines provide a foundation for implementing advanced monitoring solutions that protect personnel.

LEL Gas Safety: Is Your Facility in Compliance?



 

What is an LEL Gas Detector?

LEL gas detectors, also known as combustible gas or gas leak detectors, are safety equipment designed to detect the presence of flammable gases. The LEL or Lower Explosive Limit (LEL) is the threshold where a gas or gas mixture is the lowest concentration at which the gas can ignite and cause an explosion. LEL gas detectors monitor combustible gases, including natural gas, methane, propane, butane, volatile solvents, sewer gases, and other hydrocarbons.  Flammable gases and gas vapors are a significant safety hazard where these gases are used, may accumulate, or are a by-product of manufacturing processes.

LEL gas detectors such as PureAire’s Molecular Property Spectrometry (MPS) LEL Gas Detector offer real-time, reliable gas detection, alerting personnel before gas levels become dangerous and enhancing safety from fires, explosions, and asphyxiation in industrial, commercial, and residential environments, including oil and gas, wastewater treatment, chemical and solvent manufacturing facilities.

  • 15+ years of operational life without requiring replacement.
  • Immune to poisoning.
  • Accurate detection of over 20 combustible gases with one monitor, including hydrogen, without the need for correction factors.
  • Consistent performance in varying environmental conditions, reducing false alarms and improving reliability.
  • RS-485 interface for seamless communication with centralized systems
  • Class l & ll, Division 1, Groups B, C, D, E, F, G

Mitigate Risks: LEL Combustible Gas Detectors

The PureAire MPS LEL Monitor continuously monitors combustible gases in challenging environmental locations where these gases pose a risk, including:

  • Oil and Gas Facilities: Ensuring safety during extraction, processing, and storage operations.
  • Wastewater Treatment Plants: Monitoring for gases produced during the treatment process.
  • Chemical Manufacturing: Detecting potential leaks or accumulations of flammable substances.

Mitigating explosion risks at locations like these and others requires a structured approach to safety, including:

  1. Prevention – This includes knowing what combustible gases are in the area, ignition sources, proper ventilation systems, and installing gas detection equipment such as PureAire’s MPS LEL Gas Monitor to detect the presence of combustible gases. The MPS Gas Monitor ensures continuous real-time monitoring to detect leaks before they reach dangerous concentrations.
  2. Detection and Early Warning – LEL gas monitoring equipment provides an early warning by triggering audible and visual alarms when gas levels approach the hazardous threshold, alerting personnel to evacuate and take corrective action.
  3. Mitigation and Emergency Response – Automated shutdowns and ventilation activation happen when LEL levels reach critical limits. Alarm relays from PureAire’s MPS LEL Monitor integrate seamlessly into safety systems, automatic shut-off valves, and ventilation systems when gas levels reach unsafe levels.

OSHA Safety Regulations for Combustible Gas Monitoring

The Occupational Safety and Health Administration (OSHA) provides strict guidelines for workplaces where combustible gases are present:

  • OSHA 29 CFR 1910.146 (Confined Space Entry) which requires continuous atmospheric monitoring to prevent explosion hazards in confined spaces such as storage tanks and process vessels.
  • OSHA 29 CFR 1910.1000 (Air Contaminants Standard) – Mandates exposure limits for hazardous gases, protecting personnel from exposure to dangerous gas concentrations.
  • OSHA 29 CFR 1910.119 (Process Safety Management of Highly Hazardous Chemicals) – Enforces rigorous controls for facilities handling combustible gases to prevent catastrophic accidents.
  • NFPA 70 (National Electrical Code – NEC) – Outlines electrical installation requirements for hazardous locations.
