CNG Daughter Station Compressor

The CNG daughter station compressor is specifically designed for natural gas refueling stations, offering high reliability and broad adaptability.

The CNG daughter-station compressor is a core component of the CNG supply chain. Daughter stations are typically located in areas not served by natural gas pipelines; compressed natural gas is transported from a mother station via CNG trailers, offloaded through an offloading post, boosted and stored by the daughter-station compressor, and finally dispensed to vehicles via dispensers.

Specifically designed for daughter-station operating conditions, this product begins compression and boosting immediately after the trailer's gas source pressure naturally equalizes. It boasts an average processing capacity exceeding 1,000 m³, with a discharge rate that adapts dynamically-ranging from 1,800 Nm³/h down to 400 Nm³/h-as the trailer pressure drops, ensuring a stable and efficient gas supply to the storage cylinder bank and dispensers.

Product Features

Operating Principle and Process

1. The CNG trailer arrives at the daughter station and connects to the system via the unloading post.

2. The system first achieves natural pressure equalization; subsequently, the compressor draws in the gas directly for compression and boosting.

3. The pressurized gas is routed sequentially into the gas storage cylinder bank or supplied directly to the dispenser.

4. The dispenser refuels vehicles, while a gas detection system provides continuous monitoring to ensure safe operation.

The compressor's discharge capacity automatically adjusts based on the trailer's residual pressure (ranging from 1800 to 400 Nm³/h), ensuring efficient utilization of the trailer's gas supply and minimizing energy waste.

System Equipment Composition

A complete daughter station system typically includes:

Gas unloading post: Facilitates safe connection between the trailer and the station system, as well as gas unloading.
Daughter station compressor: The core pressure-boosting unit.
Sequence control panel: Manages priority control for gas storage and dispensing.
Gas storage cylinder bank: Buffers and stores high-pressure gas.
Dispenser: Provides precise metering and dispensing of gas to vehicles.
Gas leak detection system: Monitors for leakage risks in real time.
CNG trailer: The vehicle used to transport the gas supply.

These components work in concert to form a complete, closed-loop process spanning unloading, compression, storage, and dispensing.

Core Functions and Features

01/

Pressure Boosting and Regulation

Receives low- or medium-pressure gas from a trailer, rapidly compresses it to meet high-pressure requirements for storage and vehicle refueling, and precisely regulates output pressure to ensure safe, efficient gas delivery.

02/

Adaptive Discharge Capacity

Discharge capacity automatically adjusts as trailer pressure drops (ranging from 1800 to 400 Nm³/h) to match the needs of different unloading stages, thereby maximizing gas source utilization.

03/

Distribution and Supply Assurance

Compressed gas is systematically distributed to gas storage banks or directly to dispensers, ensuring a continuous and stable gas supply.

04/

Comprehensive Safety Design

Equipped with multiple safety measures-including overpressure protection, leak detection, and emergency shutdown-meeting high safety standards for compressed gas facilities.

05/

Intelligent Monitoring and Control

An advanced monitoring system tracks key parameters such as pressure, temperature, and operational status in real-time; it supports remote monitoring and fault early warning to ensure efficient, safe operation.

06/

Highly Integrated System

Seamlessly interfaces with unloading columns, sequencing panels, gas storage banks, and dispensers to form a reliable, comprehensive gas supply solution.
