CNG provides an economical and flexible alternative to the traditional pipeline delivery system. The operating module is simple: natural gas from the pipeline is compressed to approximately 250 bars and loaded into a tube skid. Then, it will be transported by trucks. When the CNG reaches its destination or also known as delivery point, the tube skid is then connected to the pressure regulating unit to reduce the pressure of CNG in accordance with customer’s requirement at approximately 1.4 bar.
