1.1 Skid mounted BOG recovery device


Product Description:

BOG, Boiled off Gas. Due to the cryogenic liquefied natural gas (LNG), LNG is evaporated by external heat so as to generate boil-off gas.

»  BOG compressed into the pipe network

The BOG in the tank is warmed by a heater or directly pressurized by a BOG compressor and then fed to the natural gas pipe network. The device is mainly composed of air temperature vaporizer, water bath heater (optional) and compressor, the process is simple, small footprint.

»  BOG compression CNG

The BOG was warmed by a heater and then pressurized by a high pressure compressor to 25.0 MPaG for use as CNG. The device is mainly composed of air temperature vaporizer, water bath heater (optional) and compressor, simple structure, small footprint.



»  BOG reliquefaction

The BOG gas in the storage tank is reliquefied through compression and heat exchange. The device is mainly composed of a low-temperature heat exchanger, a BOG compressor, a refrigeration compressor and a cold box. The whole process of the BOG is simple and occupies a small area.

»  BOG compressed back to the car

For the LNG gasification station, the BOG gas in the storage tank is compressed by the low-temperature BOG compressor and then returned to the LNG tanker by the gas phase during the unloading process of the LNG tanker so that the tanker truck is pressurized to realize unloading. The device is simple to operate, unload fast, and can avoid BOG loss during unloading.

Scope of application:

LNG peaking station, LNG liquefaction plant, L-CNG filling station, LNG gasification station and so on
