A new hydraulic turbine approach to increase LNG production and efficiency

Expanding liquid hydrocarbons with hydraulic turbines in place of control valves offers thermodynamic benefits that can be effectively used in all LNG liquefaction processes, including the common propane precooled mixed refrigerant (C3MR) process.Hydraulic turbines provide additional refrigeration that can be efficiently used to: Increase production at the original LNG temperature  Reduce refrigeration power to achieve the original production  Reduce end-flash by producing colder LNG.  Recent turbine design advancements directly improve reliability and further increase LNG production.A new turbine offering from the authors’ company incorporates these developments with:  Adju
