Flame & Gas Detection Application Spotlight: LNG/CNG Loading Racks

Liquefied natural gas and compressed natural gas loading racks are used for the transfer of pressurized gases between storage tanks and various transportation mediums including truck, train, or marine vessels. Protection of these facilities is critical due to the large inventory of flammable substances on-site. Acoustic gas leak and flame detection technologies could improve safety at these facilities by quickly and accurately detecting the presence of hazardous material releases.

Watch this video to see how Flame & Gas Detection devices can help increase safety at loading racks.

  Thanks Amanda,
  I am aware of Ultrasonic and infra red leak detectors and condition monitoring.
  I started using these around 2000.
  I am also aware of weld detectors various tuners and the like.
  I had forgotten about the issues the issues of gas leaks and Liquid gas leaks
  New Zealand had an issue with a leaking underground gas main that shut the city of Auckland down for 5 days.
  The City also had an issue with a ruptured underground pipeline a few years later.
  
  I will work on detection of gas leaks and variation in the thickness of pipes
  My idea is to feed the resultant signal from the sensors into condition monitoring software
  This will allow continuous monitoring of all parameter that change with the resonance of a pipe or container
  Leaks, flow, composition, variation in thickness, and the formation of sinkholes all change the resonance of pipes and containers.
  
  Would you like to be informed of progress on the gas leak front
  
  Thanks

  Hi Amanda,
  I will be setting up a trial to determine
  1/ The presence and location of gas leaks
  2/ the formation of a variation in the thickness of a pipe
  3/ The formation and location of sink hole around a pipe.
  
  Ultrasonic frequencies are easily absorbed so I will be using frequencies around 200hZ or lower
  From a safety perspective using condition monitoring is preferable because it allows for the detection of faults before they become leaks.
  Gas leak detectors generally only detect leaks.
  It would be better to detect potential leaks before they become actual leaks.
  
  My concept is to obtain a stable and precise signal that can be used by condition monitoring software.
  My friend Dr Rajendra Prasad has been working on this with me.
  We can convert weak and indistinct signals associated with resonance to strong stable signals that respon in micro and nano Hz resolution
  
  
  Details of how this works is in the following patent links.
  There is no prior art on this method of measurement.
