LNG Regasification & Pressure Regulating Skid

Product Overview

The HUAYI LNG Regasification & Pressure Regulating Skid provides an integrated solution for converting LNG into gaseous natural gas and regulating the gas to the required downstream pressure.

Depending on project requirements, the system can integrate LNG vaporization, gas reheating, pressure regulation, flow metering, safety protection, control and odorization on a skid-mounted platform. This integrated configuration can reduce field installation work and simplify the interface between major process components.

Typical Process

LNG from the storage and supply system enters the vaporization section, where it is converted from the liquid phase into gaseous natural gas.

The vaporized gas can then pass through reheating, pressure regulation and metering sections according to the required process configuration. For applications requiring odorized natural gas, an odorization system can be integrated downstream according to project requirements.

The treated natural gas is subsequently supplied to the downstream gas distribution system or end user at the specified operating conditions.

Typical System Components

Depending on the project configuration, the LNG regasification skid may include:

• LNG vaporizer

• Gas reheater

• Pressure regulating system

• Flow metering system

• Safety shut-off and pressure protection devices

• Valves and process piping

• Instrumentation and control system

• Optional gas odorization system

• Skid structure and associated auxiliary components

LNG storage tanks, unloading systems and other upstream equipment can be engineered separately according to the overall LNG station configuration.

Pressure Regulation

The pressure regulating section reduces the vaporized natural gas to the pressure required by the downstream pipeline or gas-consuming equipment.

The regulating arrangement, number of pressure reduction stages and safety protection configuration can be selected according to inlet pressure, outlet pressure, flow capacity and operating requirements.

Gas Metering

A gas flow metering system can be incorporated into the skid for monitoring and measuring downstream natural gas flow.

The meter type and instrumentation configuration can be selected according to flow range, pressure conditions, measurement requirements and project specifications.

Optional Odorization

Where odorization is required, the skid can be equipped with an odorant injection system.

The odorization configuration and dosing method can be selected according to the applicable gas supply requirements and project specifications.

Control and Safety

The skid can incorporate pressure and temperature monitoring, safety shut-off devices, alarms and automatic control functions according to project requirements.

Remote monitoring and communication functions can also be considered when required by the overall station control philosophy.

Typical Applications

The system can be configured for applications including:

• Industrial LNG gas supply

• Distributed LNG gas supply stations

• Commercial and utility gas supply

• Temporary natural gas supply

• Emergency gas supply

• Areas without direct pipeline natural gas access

• LNG satellite and regasification stations

Customized Engineering

Each LNG regasification project may have different operating conditions. HUAYI can configure the system according to project-specific information such as:

• Required natural gas flow rate

• LNG supply pressure

• Required outlet pressure

• Ambient temperature

• LNG composition

• Required gas outlet temperature

• Metering requirements

• Odorization requirements

• Control and communication requirements

• Applicable project specifications

Final equipment configuration and technical parameters should be determined based on the confirmed project operating conditions.
