Clean Energy Compression’s Bulk Gas Transportation systems have enabled customers worldwide to take advantage of the tremendous cost reduction and environmental benefits of converting to natural gas without waiting for expensive pipeline or LNG infrastructure. The PRS system is designed for pressure let down of natural gas delivered to a customer site by mobile storage. The PRS system is made up of two modules: Pressure Reduction Module (PRM) and Heating and Control Module (HCM).

REDUCED INSTALLATION COSTThe self-contained system requires minimal onsite construction which reduces installation costs.

ADVANCED HEATING CONTROLActive heating system allows flexible and controllable heating supply while maintaining efficiency.

Complete

• Semi-permanent mounting, including concrete, asphalt, and prepared gravel.

• Compact integrated footprint featuring all major systems required to reduce CNG pressure to a working pressure on one skid

• Self-contained, modular packaging

• Oversized heating system for pressure & flow transitions

• User friendly touch-screen HMI for set-point and alarm control

• Boiler utilizes natural gas from the tube trailer

• Emergency Shutdown System (ESD)

• Uses 2-stage regulation for maximum consistency of outlet pressure

• Optimized system resistance to maximize usable gas from tube trailers

• Minimized noise levels due to Main and monitor regulation on PRS

• Continuous gas supply via optimized automated trailer switching

• Clean Energy Compression’s considerable experience in building PRS units for various markets has resulted in a quality standard design to perform under a variety of conditions

• Active heating system allows flexible and controllable heating supply while maintaining efficiency

• First stage pneumatic control valves minimize the drop that occurs in much larger regulators and provides added protection in case of a regulator failure

• Increased PRS capacity reduces capital cost by reducing a customer inventory of mobile storage units

• Control screen provides user friendly display where operator can easily control and view system status and alarms

• Intelligent controls leading to improved operational efficiency and robustness

• Remote monitoring to ensure speedy maintenance response

Features & Benefits

Clean Energy Compression's CompletePRS includes proven CleanPRS technology in a package that combines portability with configurable plug-and-play installation. Each package features a Pressure Reduction Module and a Heat Control Module. The self-contained system has a smaller footprint than a standard built-in station and requires minimal on-site

construction, making it fast to install and easy to relocate. Clean Energy Compression designers and engineers have responded to the needs of the market to deliver a comprehensive sustainable CNG fueling system with minimal environmental impact.
