Potential cost of a 2-day shutdown of the molecular sieve in a natural gas plant. For an LNG plant, depending on the capacity, this could climb to over $1 million.
Liquefied natural gas (LNG) is natural gas that has been cooled to −162 °C (−260 °F). Converting natural gas to a liquid in a liquefaction plant typically involves four main processes: pretreatment, acid gas removal and dehydration, fractionation to remove heavy hydrocarbons, and liquefaction. Each of these LNG processing operations requires precise, reliable process control to ensure the continuous uninterrupted operation needed for on-time loading and shipment of liquefied natural gas.
We partner with you to select the right field instrumentation for critical measurements and reliable process control of your LNG processing operations from gas pretreatment to liquefaction. This includes highly accurate flow measurement for entrained gas and low flow applications, monitoring to ensure the removal of contaminants to trace levels from gas processed for liquefied natural gas; reliable temperature sensors, and smart field devices that ensure high system availability.
