Maximize the efficiency of your natural gas processes

Enhance your productivity in natural gas processing, liquefaction and LNG facilities

Varying compositions of raw natural gas and fluctuating process and environmental conditions challenge the efficient, uninterrupted operation of natural gas processing, liquefaction trains and related facilities. LNG storage, distribution and regasification facilities also need state-of-the-art process control for maximum efficiency. In short, your competitiveness demands greater measurement accuracy and enhanced control of all natural gas processes along the gas value chain.

  • 22%

    of global energy demand is supplied by natural gas. Demand grew 4.6% in 2018, the quickest annual pace since 2010. Demand is expected to rise by more than 10% over the next 5 years

Applications

Reliable level measurement in gas sweetening units

Raw natural gas from reservoirs contains varying amounts of acid gases (H2S and CO2). Gas sweetening units remove acid gases using a chemical absorption process. A typical process unit includes contactor (absorption) and stripper (distillation) columns. Effective level control in these columns is vital for stable operation to ensure uniform flow of amine out of the unit.

Amine treatment unit
Our expertise in the field

Guided wave radar technology offers unique benefits ensuring smooth operation and high productivity of the unit.

  • Reliable measurement even with changing product and process conditions

  • No maintenance: no moving parts unlike mechanical level instruments

  • Easy commissioning and diagnostics from HistoROM data management

  • Seamless integration into control or asset management systems

On-line monitoring of trace-level H2O

Sweet natural gas exiting the amine treatment unit is saturated with water vapor. Molecular sieve dehydration is used to obtain the very low H2O concentrations (< 0.1 ppm) required for cryogenic processes in NGL recovery units and for LNG production. Highly accurate measurement is needed to rapidly detect moisture breakthrough in the adsorbent bed to enable the operator to switch gas flow to a vessel with a freshly regenerated adsorbent bed.

Ultrasonic flow measurement in natural gas processing plants

Reliable flow measurement is crucial for optimized natural gas processing and to minimize operational challenges. Inherent challenges exist due to wet gas conditions and varying compositions of feed gas. Accurate measurement of gas flow into dehydration and sweetening units is essential for better process efficiency and to minimize problems associated with re-boiler overload and chemical losses.

Composition measurement of liquefied natural gas (LNG)

Accurate measurement of LNG composition is necessary for calculating the energy content (BTU value and Wobbe index) and monetary value of the fuel during production and at downstream custody transfer points. Composition data is essential to transactions in LNG import / export terminals, marine bunkering, and truck-loading operations. You're looking for quick, accurate analysis, preferably without having to extract a sample.

Utilities: analytical solutions for water and steam

Water and steam play important roles in natural gas processing & liquefaction. Steam is used for power generation or as a heating medium – for example in solvent regeneration in acid gas removal units, or regeneration gas for molecular sieve dehydration beds. To maximize process efficiency and safety, make-up water, cooling water, and steam must meet specific quality specifications.
