The invention relates to a
BOG comprehensive utilization
system for an LNG receiving
station. The
BOG comprehensive utilization
system for the LNG receiving
station comprises an LNG transport ship, an
LNG storage tank, an immersed pump, a high-pressure pump, a
vaporizer, a
pressure regulator A, a metering device A, a buffering tank, a
BOG compressor, a recondenser, a sea water pump, a
heat exchanger A, a
heat exchanger B, a power generation device, a
lithium bromide unit, a
waste heat boiler, a
torch and a plurality of valves. The BOG comprehensive utilization
system for the LNG receiving
station has the following beneficial effects: a gas internal-
combustion engine is used for combusting BOG for power generation, and BOG originally discharged through
combustion is reused, so that the technical effects of
energy conservation and emission reduction are realized; a heat exchange pipeline is arranged, and a free cold source is provided for an air conditioner through
seawater; while the need of a
vaporization process is met, gradient utilization of energy is realized through cold
energy recovery, and
energy conservation and emission reduction are achieved; and different
energy consumption requirements of the LNG receiving station can be met, waste can be turned into wealth,
energy loss and waste are reduced, the energy
utilization rate is increased, the gradient utilization of energy is realized, and a good good economic value is achieved.
