The BOG compressor is specially engineered to handle boil-off gases in cryogenic applications, playing a vital role in LNG logistics and vapor management. It compresses evaporated LNG vapors, commonly known as boil-off gas, to reinject them into the system or direct them for energy recovery, ensuring pressure balance and fuel conservation.

Product Introduction

In recent two years, all cities in China are building LNG stations, LNG storage equipment volatile flash vapor, that is, BOG gas, in order to make full use of this part of the gas, through the compressor will be BOG gas pressurization to a certain pressure and then directly supplied to the city pipeline network, but also can be pressurized to 250 kg to be transported to the CNG station to use.

The BOG compressor is specially engineered to handle boil-off gases in cryogenic applications, playing a vital role in LNG logistics and vapor management. It compresses evaporated LNG vapors, commonly known as boil-off gas, to reinject them into the system or direct them for energy recovery, ensuring pressure balance and fuel conservation.

This BOG compressor features a corrosion-resistant build and cryogenic-grade components, enabling it to function effectively under extreme cold temperatures. Its robust design ensures uninterrupted performance, even under variable load conditions. The compressor supports both continuous and intermittent operations, making it versatile for a range of industrial uses.

With automated controls and real-time monitoring, the BOG compressor provides operators with accurate feedback on pressure, flow, and temperature, allowing for optimized gas management. Its high-efficiency drive system reduces energy consumption, while its modular design simplifies maintenance and system upgrades.

Used extensively in LNG terminals, marine LNG carriers, and gas processing plants, the BOG compressor enhances safety, improves fuel efficiency, and ensures regulatory compliance by capturing and compressing excess vaporized gas before it escapes into the atmosphere.
