Sources of VOCs Emissions in Oil & Gas Operations VOCs emissions in oil and gas field scenarios primarily originate from upstream and midstream processes: extraction, gathering, transportation, storage, and on-site wastewater treatment. ...
PureAire Monitoring Systems is excited to announce the launch of our latest offering—the PureAire CloudConnect module, provides for internet connectivity (with Cloud storage capabilities) for our full line of Oxygen and Carbon Dioxide Monitors, as well as our Toxic and LEL Combustible Gas Detectors. Our new CloudConnect module will send continuous ...
PureAire Monitoring Systems is excited to add its 0-10 parts per million(ppm) Trace Oxygen Analyzer to our full line of Oxygen Deficiency Monitors, Carbon Dioxide Monitors, Toxic Gas Detectors, and LEL Gas Monitors. The new Analyzer measures trace levels of oxygen across a wide variety of applications where precise, ultra-low gas ...
The gas detection system should continuously monitor the area and, if gas concentrations exceed the permissible exposure limit, activate an alarm, turn off the gas at the source, and turn on the ventilation system. ...
In the event of a leak, and an accumulation of solvent vapors, an LEL gas detection monitor should activate visual and audible alarms, and turn on the ventilation system. PureAire Monitors PureAire Monitoring Systems’ line of LEL Combustible Gas Monitors is designed to meet the safety needs of pharmaceutical manufactures ...
Butane is highly flammable and explosive gas as well. Absent appropriate gas monitoring, an explosion can occur if butane vapors are ignited by a spark, heat, or open flame. ...
PureAire Monitors PureAire Monitoring Systems’ Combustible Gas Monitor (LEL) offers continuous readings of ethanol (and can also be programed to detectisopropyl alcohol, ethane, ethylene, and methyl alcohol). ...
Hydrogen generators from Peak are the safest and most convenient method of supplying high-purity carrier and detector hydrogen gas to GC instruments. We were recently contacted by a service engineer from Wasson-ECE, a Peak reseller in Singapore. Wasson is a value added partner for Agilent GC systems, selling Agilent GCs with Peak Precision generators for carrier and detector gas. Peter Tran ...
However, an odorant is normally added to natural gas to alert users if there is a leak. If a natural gas leak occurs indoors, the gas is likely to rise and remain at ceiling level until ventilated outside. ...
Ethylene is a highly flammable and combustible gas. If the gas lines used to pipe ethylene into the ripening chambers were to develop a leak, the chamber could fill with ethylene and reach combustible levels. ...
Although regulatory standards were written primarily for 4-gas confined space entry meters that have electrochemical sensors and pellistor-type combustible gas (LEL) sensors, this article is intended to include any Ion Science instrument used for industrial hygiene, including also PIDs, infrared sensors, and fixed instruments. ...
In order to ensure safety it is necessary not only for the gas meter to read accurately but also to have functional alarms that alert the worker to a hazardous condition. ...
It’s in the news every day; the natural gas production industry is experiencing record growth. The gas reserves in the United States are thought to hold enough natural gas for hundreds of years and the gas and oil industry has improved extraction techniques that make gas production more affordable and less ...
The majority of laboratories worldwide use gas cylinders to supply their analytical instruments, sample prep systems and other lab applications. ...

A risk assessment must identify all potentially explosive gases then the gas with the lowest LEL (lower explosive limit) must be selected as your target gas; this is often Methane or Pentane. ...

It is therefore necessary to examine containers before entry and this work is usually conducted with a wide variety of gas detection techniques in order to be able to assess, individually, all of the substances of greatest concern. ...

To this end, flammable gas detectors are scaled in the ‘%LEL’ range (100%LEL equating to the concentration at which as may become ignitable), toxic gas sensors are scaled in the ‘ppm’ range (parts per million), and oxygen sensors measure form 0-25% volume (with 20.9% representing the normal oxygen ...
Performance Criteria The standard ISA92.0.01 is a widely accepted standard for toxic gas detection. It defines performance requirements for toxic-gas detection instruments. ...
