Hydrogen Pressure Reducing Skids for Blending with Natural Gas
Hydrogen Pressure Reducing Skids for Blending with Natural Gas
Hydrogen pressure reducing skids (PRS) can be used for blending hydrogen with natural gas at city gate stations to meet specific gas quality requirements or to increase the use of renewable hydrogen as a fuel source. The PRS is designed to reduce the pressure of high-pressure hydrogen gas to the required pressure level for injection into the natural gas pipeline.
The PRS typically consists of the following components:
Inbuilt Safety : Being a high-pressure section two level safeties are incorporated at first stage regulator i.e. Safety shutoff loop & full capacity safety relief valve to safeguard the further equipment's in case of malfunction of the regulator.
Pressure Regulator : The pressure regulator reduces the pressure of the high-pressure hydrogen gas to the required level for injection into the natural gas pipeline.
Pressure Gauge : The pressure gauge measures the pressure of the hydrogen gas before and after the pressure regulator.
Safety Relief Valve : The safety relief valve is a safety device that opens automatically to relieve pressure in case of an overpressure event.
Filter : A filter is typically used to remove any impurities or moisture from the hydrogen gas before it enters the natural gas pipeline.
Flow Meter : A flow meter is used to measure the flow rate of the hydrogen gas entering the natural gas pipeline.
Control System : A control system is used to monitor and control the operation of the PRS.
The hydrogen PRS can be designed to operate automatically or manually, depending on the specific application requirements. The PRS can be installed as a standalone unit or as part of a larger hydrogen injection system. It is important to follow all applicable regulations and industry standards when designing, installing, and operating a hydrogen PRS for blending with natural gas injection at city gate stations.
