Detecting Butane in the Oil & Gas Industry

Where does Butane come from?

Butane is derived from the refining of crude oil and natural gas, and it can also be a by-product of biomass and landfill gas. As a highly flammable gas, butane ignites easily when exposed to heat, flames, embers, or sparks, presenting a significant explosion risk. To mitigate this danger, it should only be used in well-ventilated areas, away from potential ignition sources, and never in confined spaces.

During transportation, butane is stored as a liquid under pressure. This is because it rapidly converts from liquid to gas under normal temperature and pressure conditions. By storing butane in liquid form under pressure, the risk of explosion is reduced, ensuring safer storage, transport, and controlled vaporisation when it is needed.

What are the side affects of inhaling?

Accidental inhalation of butane can lead to a range of symptoms and health complications, with the severity depending on the concentration and duration of exposure. Immediate effects may include:

  • Dizziness and lightheadedness
  • Headaches and confusion
  • Nausea and vomiting
  • Difficulty breathing and chest pain
  • Loss of consciousness in severe cases

If exposure is prolonged or repeated, butane can cause long-term health issues, such as:

  • Respiratory system damage, which increases the risk of chronic conditions like asthma, bronchitis, or emphysema.
  • Central nervous system effects, including cognitive impairments, memory loss, mood swings, anxiety, and depression.
  • Heart complications, including a higher risk of sudden sniffing death syndrome (SSDS), which can cause fatal irregular heart rhythms.
  • The potential for dependence and abuse, driven by its psychoactive effects.

Butane TWA and STEL

Long-term exposure limit (8-hour TWA): WEL 1000 ppm 1750 mg/m³

Short-term exposure limit (15-minute): WEL 1250 ppm 2180 mg/m³

Products to detect Butane

Honeywell Microclip XL

The BW GasAlertMicroClip XL portable multi-gas detector can be configured to monitor a range of combustible gases, including LEL, Hydrogen Sulphide (H2S), Carbon Monoxide (CO), and Oxygen (O2).

While it shares the same core design as the bestselling BW MicroClip, the BW GasAlertMicroClip XL has been redesigned and rebranded. It now features a cutting-edge new battery design that provides up to 18 hours of operation—eight hours longer than its predecessor.

To detect Butane, you can use an LEL (Lower Explosive Limit) sensor. These sensors are specifically designed to detect combustible gases, including hydrocarbons like Butane, by measuring the concentration of gas in the air as a percentage of its LEL.

Honeywell Sharepoint

Honeywell XRL

The Honeywell Sensepoint XRL Fixed Gas Alarm is ideal for industrial environments, offering a reliable solution for detecting selected gases in the atmosphere.

Although the device is hardwired to a wall, it provides remote access through an intuitive smartphone app. This app enables real-time measurements from up to 10m away, along with quick calibration, configuration, and bump tests.

Thanks to its modern design, the device is robust enough to withstand various outdoor environments. Additionally, its straightforward installation and easy maintenance help keep costs low.
