LNG Dispenser Skid

Qingdao Lenado Intelligent Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of lng dispenser skid in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk customized lng dispenser skid from our factory.

The skid-mounted LNG vehicle refueling station produced by our company integrates key components-including an LNG dispenser, cryogenic pump, unloading vaporizer, tank vaporizer, piping, and control valves-centrally mounted on a single skid. This design offers high integration, easy installation, flexible mobility, and user-friendly operation. It only requires an LNG tanker truck to supply LNG as the gas source, which reduces the hazards associated with system design and equipment installation. This not only lowers equipment costs but also shortens the construction period. Equipped with an automatic PLC control system, the station automatically performs process control functions such as data acquisition, combustible gas monitoring, pump shutdown on overpressure, and pump startup on low pressure, making the operation simple and reliable.

1. Unloading Process

1) Self-pressurization unloading:​ The LNG tanker truck is pressurized by a vaporizer, and LNG is transferred from the tanker to the LNG storage tank of the refueling station.

2) Cryogenic pump unloading:​ LNG is transferred from the LNG tanker truck to the LNG storage tank of the refueling station by the LNG pump of the refueling station.

2. Pressure Regulation Process

During the unloading process, a portion of LNG is drawn from the tank by the LNG pump, then pressurized through the LNG vaporizer and returned to the tank. When the saturation pressure of the tank reaches the set pressure, the vaporization stops.

3. Refueling Process

LNG is drawn from the storage tank by the LNG pump and dispensed into vehicles through the LNG dispenser.

1. Comprehensive functionality, incorporating: refueling, self-pressurization unloading, pump unloading, tank pressurization, and temperature regulation.

2. All main process pipelines adopt vacuum-insulated piping, and critical flange connections utilize vacuum flanges.

3. High degree of automation: all commonly used functions of the station control system are performed by the PLC through pneumatically actuated shut-off valves, eliminating the need for frequent manual operation by personnel.

Supports self-pressurization unloading, pump unloading, and simultaneous self-pressurization and pump unloading.

Fast pressurization speed with convenient adjustment, improving unloading efficiency and simplifying the process flow.

Refueling of vehicles by pump can be performed simultaneously during unloading, with the unloading and refueling operations not interfering with each other.

During unloading, gas from the storage tank can be discharged into the liquid phase of the tanker truck for liquefaction, eliminating the need for venting.

An optimized pump skid cover design significantly reduces heat ingress into the system.

A closed-loop process ensures operational safety and minimizes natural gas loss, making it environmentally friendly and safe.

Ultra-insulating vacuum piping technology minimizes cold loss and venting to the lowest possible level.

Exquisite process technology, excellent overall stability, and quality installation service result in high customer satisfaction.
