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.

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

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.

Our expertise in the field

Our TDLAS analyzers support you in this task as they help to quickly detect adsorbent bed saturation and breakthrough.

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.

Sentasy’s process ultrasonic gas flow meter precisely measures dry and wet gases in all gas processing steps including sweetening, dehydration, fractionation, and NGL recovery

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.

Our expertise in the field

The Kaiser Raman analyzer measures LNG composition directly in the cryogenic liquid, assuring fast response without the need to vaporize 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.

Our expertise in the field

We offer a wide instrumentation portfolio dedicated to water and steam analysis and treatment.

LNG custody transfer truck loading-offloading skids

LNG truck loading helps distribute natural gas in areas where there is no pipeline network connecting power plants, industrial and residential customers, and the transport sector. You're looking for an integrated and compact solution that provides measurement of quantity and composition to determine energy content, without sample extraction.

Our expertise in the field

We offer complete design, engineering, procurement and construction of LNG truck loading and unloading solutions, and a unique small footprint skid design with integrated LNG composition measurement and energy calculation.
