Maximize the efficiency of your natural gas processes

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.

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.

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.

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.
