LNG Satellite Station Solution

Solution Overview

An LNG satellite station provides a localized natural gas supply solution by receiving LNG from road tankers, storing it in cryogenic storage facilities and converting the LNG into gaseous natural gas for downstream distribution or industrial consumption.

HUAYI can configure the LNG gas supply system according to required gas capacity, inlet and outlet pressure, LNG storage requirements, site conditions and downstream gas demand.

Typical Process

LNG is transferred from the delivery tanker to the storage system. Depending on the station configuration, tank pressure can be maintained through a pressurization system. LNG is then supplied to the vaporization system, where it is converted from liquid to gaseous natural gas.

The gas can subsequently pass through pressure regulation, metering and odorization before being delivered to the downstream gas network or industrial gas users.

Integrated Functions

The solution can integrate:

• LNG unloading and transfer

• LNG storage and tank pressurization

• LNG vaporization

• Gas pressure regulation

• Gas flow metering

• Gas odorization

• Emergency shut-off and pressure relief

• Pressure and temperature monitoring

• Instrumentation and electrical control

• Remote monitoring according to project requirements

Safety and Control

Depending on the project configuration, the system can incorporate cryogenic emergency shut-off valves, pressure relief devices, gas-phase overpressure protection, grounding arrangements and instrumentation for monitoring pressure, temperature and other operating parameters.

Control and monitoring functions can be configured according to the required operating philosophy and project specifications.

Typical Applications

• City gas supply

• Industrial natural gas supply

• Areas without pipeline natural gas access

• Supplemental or peak gas supply

• Temporary or distributed LNG gas supply projects

Project-Specific Engineering

LNG satellite station configurations vary significantly according to gas demand, storage capacity, operating pressure, ambient conditions and local project requirements.

HUAYI can engineer the system according to project-specific gas flow capacity, LNG storage requirements, outlet pressure, equipment arrangement, instrumentation, control requirements and applicable project specifications.
