Integrated Natural Gas Pressure Regulating & Metering Skid

Product Overview

HUAYI Integrated Natural Gas Pressure Regulating & Metering Skid is engineered for high-capacity natural gas transmission, distribution and industrial gas supply applications.

The integrated skid-mounted system can combine gas filtration, gas heating, flow metering, pressure regulation, instrumentation, valves and process piping within a factory-assembled configuration. Associated pigging equipment can also be supplied according to pipeline and project requirements.

A reference project configuration incorporates multi-stage filtration, ultrasonic and turbine flow metering, hot-water heat exchange and multi-group pressure regulation for high-flow natural gas service.

Final process design, equipment configuration, instrumentation and component selection are engineered according to the gas composition, flow rate, inlet and outlet pressures, operating temperature, metering requirements and applicable project specifications.

Reference System Configuration

A reference system can include:

• 1 set of pig launcher and receiver equipment

• 1 integrated filtration, metering and pressure regulating skid

• 2 filter separators

• 2 ultrasonic flow meters

• 2 hot-water heat exchangers

• 12 pressure regulators

• 2 turbine flow meters

• 2 vertical gas filters

• Supporting manifolds and process piping

• Process valves

• Pressure and temperature instrumentation

• Associated control and monitoring components

The above configuration represents a reference project and can be modified according to specific operating conditions and customer requirements.

Reference Technical Parameters

The above values are based on a reference project configuration. Final design parameters are subject to project-specific process conditions and engineering confirmation.

Key Functions

Gas Filtration

The reference configuration incorporates vertical gas filters and filter separators to remove solid particles and entrained liquids from the natural gas stream, helping protect downstream metering and pressure regulating equipment.

Gas Heating

Hot-water heat exchangers can be incorporated to provide gas heating before or during pressure reduction where required by the process conditions. Heating capacity and configuration are determined according to inlet gas temperature, pressure reduction ratio, gas flow and required outlet temperature.

Flow Metering

The reference configuration includes both ultrasonic and turbine flow meters. Metering technology and arrangement can be selected according to project accuracy requirements, operating range and applicable measurement specifications.

Pressure Regulation

Multiple pressure regulators can be arranged according to the required flow capacity, pressure reduction ratio, operating philosophy and redundancy requirements. The regulating system is engineered according to the specified inlet pressure range and required downstream pressure.

Pigging Support

Associated pig launcher and receiver equipment can be supplied for pipeline inspection, cleaning and maintenance requirements when included within the project scope.
