LiBro® Pre-cooling Technology

The LiBro® unit, Lithium Bromide based Absorption Refrigeration unit, is integrated with Air Products® AP-N LNG Process and the chilled water produced in the LiBro® unit is used for precooling of the natural gas and cooling of N2 refrigerant for improved LNG train efficiency. Produced chilled water is also used for cooling of the gas turbine combustion air for maximizing output of gas turbine driver.

With the LiBro® unit integration, the overall efficiency of LNG train is improved, greater gas turbine power is made available, and increased LNG production capacity with the gas turbines selected is achieved.

[Key features]

  • Pre-cooling technology for liquefaction system
  • Capability to combine with N2 expander, SMR and others.
  • Proven technology widely used for centralized air conditioning application onshore
  • Stable performance under sea motion conditions with proprietary technology of MODEC
  • Usage of waste heat from gas turbine exhaust as motive power
  • Verified effectiveness and performance by full scale dynamic motions tests
  • More efficient production with Cooled GT intake air
  • Whole system is designed as absolute no liquid-leak of Lithium Bromide and no refill operation is required.
