Flow measurement devices for natural gas and LNG, monitoring of high-pressure natural gas injection to produce crude oil
Measurement solutions for Liquefied Natural Gas
Quality and composition-based measurement of drying, filtering and liquefaction
After the natural gas entering the liquefaction plant has been measured by a Custody Transfer metering system, the filtering and liquefaction process can start. During that process, KROHNE Ultrasonic OPTISONIC flowmeters are used to measure the natural gas flows and in the same process the coolants used in the cold boxes. KROHNE OPTIWAVE and OPTIFLEX level instrumentation is used to measure the level in separators, scrubbers and tanks. CalSys (AMADAS Analyser Management) software systems guarantee the performance of the analysers used to determine the quality of the natural gas and LNG.
Monitoring of loading and fuelling
KROHNE OPTIMASS Coriolis meters are used in small scale LNG and break bulk projects to measure the amount of LNG that is loaded in a truck or bunker ship. KROHNE also supplies custody transfer approved delivery systems on LNG tanker trucks. These systems include an OPTIMASS Coriolis flowmeter, a SUMMIT 8800 flow computer and a ticket printer, all per local metrology regulations.
Regasification – Converting LNG to natural gas
In receiving terminals KROHNE ultrasonic flowmeters are used to check the delivered amount of LNG and the amount of boil of gas that is being returned to the shuttle during offloading. During regasification, KROHNE flowmeters are used to measure natural gas, with process or custody transfer accuracy, and seawater that is pumped through the heat exchanger.
Storage and shipping – Delivery flow monitoring of cryogenic LNG
For loading and unloading of LNG shuttle tankers, KROHNE flowmeters and Custody Transfer metering systems are used to measure the volume of LNG and Boil-Off gas. KROHNE also provides analyser systems to measure the LNG quality and calorific value. KROHNE L-QRS software is used to fully automatically issue the Bill of Lading and Quality Release Certificate directly after loading or unloading has been completed, without the need for manual sample handling.
