Design

The SOFREGAZ BOG Recondenser is installed in a bypass of the header between the LNG in-tank pumps and the LNG high pressure pumps.

Only the quantity of LNG required for BOG condensation is fed to the BOG Recondenser.

Advantages

LOW OPEX

  • Low pressure drop between BOG compressors outlet and BOG Recondenser
  • Adjustment of the operating pressure in the vessel in accordance with LNG Terminal operation

LOW CAPEX

  • Reduced vessel size
  • Reduced footprint

SMOOTH OPERATION

  • Only two control loops
  • Feed forward controls
  • Very low turndown
  • Stable pressure at LNG high pressure pumps suction
  • Maintenance without LNG Terminal shutdown

Options

  • Nitrogen ballasting for Wobbe index adjustment
  • Control of LNG in-tank pumps VFD
