Boost reliability of your natural gas liquefaction processes
Minimize unforeseen shutdown and downtime of gas processing and liquefaction process trains
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.
>USD 200K
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.
How we can help
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.
Coriolis technology offering multivariable measurement with optimized performance for liquids with entrained gas – MFT (Multi-Frequency Technology)
Multivariable vortex flow meter with excellent measuring accuracy at low flow rates
Ensure gas meets specifications for LNG cryogenic liquefaction: Tunable Diode Laser Absorption Spectroscopy (TDLAS) analyzers provide fast, accurate on-line measurement of water (H2O) and carbon dioxide (CO2) in amine treatment units
Highest plant availability and safety with reliable temperature sensor technology
Heartbeat Technology: diagnostics, verification and monitoring functions ensure high system availability and safety with minimal effort
Applications
Precision flow measurement for entrained gas applications
Cryogenic flow applications in an LNG liquefaction plant bring measurement challenges due to two-phase flow conditions. Variations in temperature and pressure drop result in vaporization and entrained gas that cause under- or over-read, or stops the measurement altogether.

No maintenance and compact design enabling installation flexibility
Heartbeat technology enables inline verification without process interruption
Improved low flow measurement with Vortex flowmeters
Vortex flowmeters have become the workhorse in LNG plants for both liquid and gas applications but most vortex flowmeters lose signal at low flows and measure inaccurately below a Reynolds number of 20,000.

We help to overcome these challenges and more. Endress+Hauser’s Vortex flow meter is an excellent choice because of its low flow performance, robustness against temperature shock and vibration, and multivariable (pressure & temperature) options. For gases, liquids and steam.
Improved signal processing leads to optimum turndown: starts measuring 16% lower in Reynolds than any other vortex flowmeter in the market and versions with integrated two-line size reduction measure 76% lower
Most linear vortex body with flat accuracy down to Reynolds no 10,000
PremiumCal guarantees excellent measuring accuracy +/- 0.65% (liquids) / +/- 0.9% (gas) enabling highest availability of your LNG plant at low flow rates
Precise temperature measurement plays a vital role in gas processing facilities. Temperature differences more than the stipulated limits between the natural gas and amine / glycol entering the contactor in gas sweetening and dehydration units results in gas condensation, foaming and losses. Also, reliable monitoring of temperature across the heat exchanger walls is required to detect fouling.
On-line monitoring of H2S and CO2 in gas sweetening
Gas sweetening processes remove acid gases (H2S and CO2) from sour gas to meet specifications for cryogenic liquefaction. Measuring H2S and CO2 concentrations in sour gas at the inlet and sweet gas at the outlet of amine treatments units is important for control and optimization of the treatment process to ensure the quality of LNG feed gas and prevent potential damage to plant equipment during liquefaction.

Tunable Diode Laser Absorption Spectroscopy (TDLAS) analyzers are proven to be highly effective in these critical measurements.
Exceptionally fast response to H2S and CO2 concentration changes, an important performance characteristic for control of amine treatment units
Patented Differential Spectroscopy technique measures H2S at low ppm levels
Low maintenance and OPEX costs, as no cylinders of carrier and combustion gases, or lead acetate tape are required to perform measurements
Non-contact laser measurement avoids fouling and corrosion for reliable long-term operation of your LNG plant
The Oil & Gas industry operates in tough environments. You're looking for better visibility into the condition of your process equipment to avoid costly unscheduled maintenance and downtime, reduce maintenance costs, and increase system availability.
