LNG Satellite Station

LNG satellite stations are facilities that handle LNG transported from LNG storage terminals through gas tank trucks or trains. The system consists of LNG storage tanks, vaporizers, heat control devices, etc. Establish LNG virtual pipelines through LNG satellite stations. This allows natural gas to be transported to remote areas that natural gas pipelines cannot reach. The station is typically designed to meet a demand of over 1000 Nm3/hour and has multiple LNG storage tanks and vaporizers.

1. Flexibility: LNG satellite stations are more flexible compared to large LNG receiving stations, and can be quickly built and put into operation as needed. This is very important for some small and medium-sized towns and special manufacturers that need to use clean energy.
2. Moderate scale: The scale of LNG satellite stations is usually moderate, as they do not require the same storage capacity as large LNG receiving stations and can also meet certain supply needs.
3. Flexible transportation methods: The transportation methods of LNG satellite stations are relatively flexible, and suitable transportation methods can be selected according to the actual situation, such as railway, water transportation, etc.
4. Convenient operation and management: LNG satellite stations usually adopt advanced automation control systems, which can achieve remote monitoring and operation, greatly improving the convenience and efficiency of operation and management.
5. Low operating costs: Due to the moderate scale of LNG satellite stations, more economical and reasonable equipment and technology can be adopted, thereby reducing operating costs.
6. Environmental friendliness: As a clean energy source, the use of LNG satellite stations can reduce the impact on the environment and meet environmental requirements.

Discharge Stations: The LNG Satellite Plant receives its supply through cryogenic LNG containers. Transfer operations are managed by operators at two stations, utilizing cryogenic pumps and allowing for simultaneous operations. These discharge stations facilitate the transfer of LNG to storage reservoirs.

Storage: The station houses three horizontal cryogenic reservoirs, each with a maximum capacity of 200 m3. These reservoirs consist of inner (reservoir) and outer (containment) tanks, equipped with thermal insulation.

Supply: The LNG Satellite Plant delivers natural gas to the Vitória Thermoelectric Power Plant via a dedicated pipeline, maintaining suitable pressure and temperature levels. Prior to transfer, the stored LNG undergoes regasification (conversion from cryogenic liquid to gas with a temperature above 0°C) and processing. This process ensures the safe operation of the installed equipment and includes the following:

• Regasification and Heating Unit: Regasifies the LNG to enable conveyance at approximately 15°C within the pipeline.
• Adjustment and Measurement Unit: Maintains a constant gas pressure within defined limits in the pipeline.

Odorization Unit: Adds odorants to natural gas, enhancing its detectability and ensuring safe distribution and use.

Management and Control Unit: Enables autonomous operation of the LNG Satellite Plant and remote monitoring of key parameters such as pressure, stock levels, temperatures, gas detection, etc.
