Understanding LNG, CNG and BOG Gas Compressors in Natural Gas Applications

The Role of Advanced Compression Technology in Modern Natural Gas Infrastructure

Natural gas has become an important energy source in global energy development due to its high efficiency, cleaner combustion characteristics, and wide range of applications. From transportation fuel and industrial energy supply to storage and processing systems, natural gas requires reliable equipment to ensure stable operation throughout the entire supply chain.

Among various types of energy equipment, gas compressors play a critical role in maintaining gas pressure, improving transportation efficiency, and supporting safe and stable operation. Different natural gas applications require different compression technologies, including LNG compressors, CNG compressors, and BOG compressors.

As a professional gas compressor manufacturer, Bengbu Kery Compressor Co., Ltd. (KERY) focuses on the research, development, and manufacturing of gas compression equipment. With more than 20 years of industry experience, KERY provides customized compressor models according to different intake pressures, gas supply conditions, and application requirements, helping customers achieve efficient and reliable natural gas utilization.

What is an LNG Compressor?

LNG (Liquefied Natural Gas) is natural gas that has been cooled to a liquid state for easier storage and transportation. During LNG processing, storage, and refueling operations, maintaining proper pressure control is essential for ensuring system efficiency and safety.

An LNG compressor is a key piece of equipment used in LNG-related applications to manage gas pressure and support stable operation of natural gas systems.

LNG compressors are commonly used in:

Because LNG applications involve different operating conditions, compressor systems need to be adapted according to factors such as gas supply requirements, pressure levels, and installation environments.

KERY provides customized LNG compressor designs to meet different project requirements. With integrated skid-mounted structures and intelligent control systems, KERY compressors help simplify installation, improve operational efficiency, and support reliable long-term performance.

What is a CNG Compressor?

CNG (Compressed Natural Gas) is widely used as an alternative fuel in transportation due to its efficiency and environmental advantages. In CNG refueling stations, compressors are essential equipment for increasing natural gas pressure and ensuring that vehicles can be supplied with fuel efficiently.

A CNG compressor system helps transform natural gas into a high-pressure fuel source suitable for storage and vehicle refueling.

The main applications of CNG compressors include:

• CNG vehicle refueling stations
• Natural gas distribution facilities
• Industrial gas supply systems
• Energy infrastructure projects

A reliable CNG compressor should provide:

KERY designs CNG compressor systems according to different station capacities, gas supply conditions, and customer requirements. Through customized models and advanced control technology, KERY supports efficient operation and maintenance of refueling stations.

Why is BOG Compression Important?

During LNG storage and transportation, temperature changes may cause a small amount of LNG to evaporate and generate Boil-Off Gas (BOG). If BOG is not properly managed, it may increase storage pressure and lead to unnecessary energy loss.

A BOG compressor is designed to recover and compress evaporated natural gas, allowing it to be reused instead of being wasted.

BOG compression plays an important role in:

By efficiently handling BOG, operators can improve energy utilization and create a more sustainable LNG operation process.

KERY develops BOG compressor systems according to different LNG storage and transportation requirements, providing reliable equipment for gas recovery applications.
