Abstract

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.

Description

Technical field

[0001] In particular, the present invention belongs to the technical field of evaporation gas in liquefied natural gas, and more particularly to an LNG (liquefied natural gas) receiving station BOG (evaporation gas) comprehensive utilization system. Background technique

[0002] At present, there are two main types of operating conditions in China's large LNG receiving station. First, unload ship operating conditions, one is the external operational operating conditions. When the unloading operating conditions, the discharge enters the LNG (liquefied natural gas) storage tank, and a certain amount of BOG (evaporation gas) occurs, so that the pressure of the LNG tank is raised, and the portion of the BOG will return to the pipe through the gas phase. On the LNG board, the amount of flash generation and returning to the ship mutually cancel each other, the total amount of system BOG may increase, the key depends on the integration of multiple factors such as unloadi...
