BE SAFE, WITH NETSAFETY

Oil refineries, processing plants, pipelines, storage farms, LPG/LNG plants, and offshore platforms all utilize or produce a wide range of hazardous combustible and toxic gases. In addition, the processes involved in each can produce non-toxic gases which, when accumulated in high concentrations, depletes oxygen causing a hazardous condition to personnel who occupy the area without proper protection. Where hazardous conditions are the greatest, it is essential to have monitoring system that constantly monitor a facility's conditions even if personnel are not present. Hand-held/personal monitors don't have the ability to detect concentrations of combustible gases in unoccupied areas that are hazardous to equipment, personnel, and the facilities themselves. Depletion of oxygen is hazardous to individuals entering any unoccupied areas, whereas any amount of toxic gases can have serious health implications (even death) for any personnel entering an unoccupied area where they are present.

LPG/LNG FACILITIES
Liquefied Natural Gas (LNG) with its major component methane is drilled from the ocean bed in various parts of the world (especially the North Sea) using either fixed exploration platforms or Floating Production Storage and Offloading (FPSO) vessels. The natural gas is transported via pipelines and tankers to the onshore facilities where it is stored in special tank farms before it is distributed to the various users. Beside this natural resource, the petrochemical industry has developed various distillation and cracking processes that produce light hydrocarbon gases like methane, ethane, propane, butane and their derivates ethylene, propylene, butylene, etc. These refined gases, are compressed and liquefied for storage purposes and known commercially as Liquefied Petroleum Gases (LPG). One of the major concerns associated with the LNG/LPG facilities is the fugitive emissions and liquid spills that evaporate very fast when exposed to the atmospheric pressure. The light methane gas migrates very fast over large areas hence the need for reliable, fast methane monitoring, over large areas of pipelines and storage facilities. The LPG, which contains light hydrocarbon mixtures (C1-C4), is heavier than air and tends to accumulate in low areas thus posing a fire/explosion hazard in the congested production and pipelines manifolds areas. In addition to gas monitoring systems, Optical Flame Detectors and advanced CCTV Flame Detectors provide enhanced coverage of the LPG/LNG facilities.

COMPRESSORS AND PUMPS
Facilities with compressors, pumps, and valves also require continuous gas and flame monitoring. These areas are prone to spills and fugitive emissions that, if undetected, can cause extensive damage to the entire facility. The combination of heat, pressure, and vibration in compressor decks can create leakage. This, along with broken seals and gaskets in valves or pumps, provide the fuel that can come into contact with heated parts and an ignition source to develop into a fire. Flame and gas monitors minimize theses risks, and even provide a system to monitor for the maintenance needs of equipment. The monitors should be installed in areas overlooking compressors and pumps.
