Optimized Boil-off Gas (BOG) Solutions

Product storage tanks provide a regulated environment in which chemicals are carefully maintained in order to reduce hazards and potential degradation. Consistent and reliable control of storage temperatures requires solutions which deliver monitoring accuracy and the optimal choice of insulation and coolant. GEA’s expertise in cooling technologies is integrated with its ability to identify BOG solutions with minimal maintenance cost, maximum energy saving and easy installation, based on customer requirements.

The Boil-off Process

Refrigerants based on ammonia or hydrocarbons – as well as liquid propane, propylene, and ethylene – are stored in special vessels at low temperatures. Ambient warmth raises this temperature. The resulting vapors must be vented to avoid pressure build up. They are changed to liquid form and returned to the storage vessel. 

Flexibility

GEA’s BOG solutions are customized for each application and utilize the compressor type suited to meet customer requirements and specifications, including:

  • Oil-injected screw compressors, comfortably limiting oil carryover to <1ppm (parts per million)
  • Oil-free compressors (dry screw or piston) 

Applications

  • BOG compression and refrigeration in fertilizer plants employs screw compressor packages and condensing systems for ammonia boil-off systems. 
  • BOG compression and refrigeration in hydrocarbon storage facilities is enabled by GEA’s line of API-619 compliant compressors, which are also uniquely suited for tank loading & unloading facilities. 
  • BOG condensing units in LNG plants.

Safety Excellence

GEA’s compliance with health, safety and environmental regulations supports international standards of best practice and promotes operational efficiency. Site layout and logistics complete the holistic approach to tank and storage cooling, with isolation and available space constraints all taken into consideration.

Optimization

GEA’s global oil & gas team delivers complete boil-off packages which reduce the utilities consumption for classified and safe areas.
