LumaSense Technologies® explains how its range of temperature monitoring equipment can help to keep assets efficient and safe
LumaSense Technologies® designs and manufactures a range of products and systems to monitor critical temperature applications, of particular use to the upstream and refining sectors of the oil and gas industry. Its equipment, from single-spot infrared radiation pyrometers to thermal vision and imaging systems, can be used to monitor processes accurately and provide reliable temperature readings throughout production infrastructure.
For gas detection and analysis, LumaSense also produces analysers, monitors, and detectors which use the latest photoacoustic spectrometry (PAS) and non-dispersive infrared (NDIR) technology.
The optimal operation of sulphur recovery units (SRUs) requires the measurement and control of a complex sequence of processes. Of particular importance is the accurate control of the reaction furnace temperature to avoid damage to the refractory wall at high temperatures, and the prevention of ammonium salt from plugging the converters at low temperatures.
Installations that use the reaction furnace to incinerate waste gases such as ammonia and hydrocarbons must maintain an adequate temperature to assure gas destruction. Advanced processes, such as O2 enrichment, normally involve even higher temperatures and demand close monitoring.
The LumaSense E²T Pulsar family of detection systems are designed for continuous and instantaneous measurement of refractory temperature, gas temperature or integrated temperature in a given vessel. Measurements are calculated via infrared technology, while the unit is kept away from heat, vibration and corrosive gases.
Flare stack monitoring
Pilot flame detection must be monitored to assure ignition of gases during flare operation. Continuous monitoring of pilot flames and flared gases is critical to ensure that the gases will be ignited and to confirm compliance with government-set pilot status recording requirements.
LumaSense’s E²T QUASAR family of detection systems are built for continuous monitoring of pilot flame (PM), flared gases (FM) and smoke particulate (SM) from flare stacks. The optical viewfinder and variable fields of view allow the QUASAR to be positioned up to 400 m from the flare stack.
Critical vessel monitoring
Critical vessels can also be notoriously difficult to monitor, as extreme temperatures and temperature variability pose significant challenges to traditional methods. LumaSense thermal imaging cameras and LumaSpection™ systems accurately measure temperature and operate by using reliable infrared technology. These high-tech instruments can operate remotely and can precisely determine the object temperature and temperature distributions, even on small objects. These systems also have the ability to see through flames and detect weak parts before they lead to critical damage.
Dissolved gas analysis
Within refineries and other sites, transformer condition assessment and failure analysis is a high priority. Electrical and thermal stresses on insulating materials – arcing, corona discharge, sparking and overheating – can result in transformer faults. The accumulation of such stresses on the insulating material results in their breakdown, and the release of different gases.
Detecting these gases via dissolved gas analysis (DGA) systems provides a sensitive and reliable way to determine the type of pending or occurring fault – so much so that DGA of transformer insulating oil is considered the single best indicator of the transformer’s overall condition.
LumaSense’s SmartDGA online diagnostic methods can therefore improve service reliability, avoid transformer failure and defer capital expenditures for new transformers.
