LCNG filling station is a kind of multifunctional filling station using LNG as gas source to provide CNG vehicle alternative fuel. It can fill all kinds of CNG modified vehicles with gaseous CNG and inflate large-capacity CNG special transport semi-trailer, that is, it has the functions of CNG filling mother station, filling standard station and filling sub-station.
LNG gasification filling machine station
L-CNG gas filling system is mainly composed of LNG cryogenic storage tank, storage tank booster gasifier, unloading truck booster gasifier, high pressure cryogenic pump, high pressure air greenhouse gasifier, sequence control panel, gas cylinder group (or gas storage well), CNG gas filling machine, station control system.
L-CNG vehicle refueling station is a system for refueling CNG vehicles with liquefied natural gas as the gas source. Liquefied natural gas from the LNG cryogenic storage tank through the high-pressure cryogenic liquid plunger pump, into the high-pressure air temperature type gasifier (the annual average temperature is lower than the set 10 degrees should also be added to the reheater) gasification to normal temperature, through the sequence control panel distribution into the gas storage cylinder group, the CNG gas machine after measurement to the CNG car gas. It can be built alone, can also be built in conjunction with LNG filling stations, or as a supplement to the existing CNG filling stations, clean CNG can minimize the damage to automotive equipment and environmental pollution.
The LNG/L-CNG joint station has the refueling capacity of both LNG and CNG, which can meet the demand of large vehicles for LNG fuel and the common CNG refueling demand of small family cars and taxis. The gas supply of the joint station is LNG, and the gas supply is single and abundant, and the transportation economy of LNG is much higher than that of CNG, which is the most popular alternative energy of petroleum at present.
Process flow
The liquefied natural gas delivered by the LNG tanker is supercharged by the LNG unloading supercharger, liquefied in natural pressure into the LNG cryogenic liquid pump using the principle of pressure difference, and the return air valve of the cryogenic liquid pump is opened to start precooling. The pre-cooled and vaporized natural gas of the LNG cryogenic liquid pump is emptied through the EAG heater. When the precooling temperature is reached, the LNG cryogenic liquid pump will automatically start. The liquefied natural gas is pressed into a high-pressure low-temperature carburetor, and pressurized to become high-pressure gaseous natural gas, and stored in the storage cylinder group, and then filled into various CNG modified cars or natural gas steel through the gas filler
LNG filling station
The skid-mounted LNG truck filling station produced by our company integrates the refueling machine, cryogenic pump, unloading supercharger, storage tank supercharger, pipeline, control valve and other equipment in a single skid body, which has the characteristics of high integration, easy installation, flexibility, safety and reliability, and easy operation.
Basic technical parameters:

Process flow:
- Unloading process
1) Self-pressurized unloading: There is a supercharger to pressurize the LNG tanker and transfer the LNG in the tanker to the LNG storage tank of the refueling station.
2) Cryogenic pump unloading: the LNG in the LNG tanker is transferred to the LNG storage tank of the refueling station by the LNG pump. - Pressure regulation process
During unloading, LNG pump is used to extract part of LNG from the storage tank through the LNG gasifier to adjust the pressure and enter the storage tank. When the saturation pressure of the storage tank reaches the set pressure, the gasification stops. - Gas filling process
The LNG in the storage tank is extracted by the LNG pump, and the LNG is added to the car through the LNG refueling machine.
Product advantage
- High integration; The intensive nature of the skid device determines that the design and production of such products must make full use of the limited space to achieve a better configuration effect, so the skid device is compact and can reduce the footprint than the traditional installation method.
- High reliability; The production and assembly of the skid installation equipment are completed in the factory, and the assembly environment is relatively good compared with the site. Can make full use of the advanced production equipment of the equipment manufacturer’s factory; Take full advantage of the advanced inspection equipment in the equipment manufacturer’s factory.
- Simplify the process; While ensuring safety and efficiency, it greatly simplifies the process flow of L-CNG filling station, which has the functions of self-starting at pre-cooling temperature, self-cutting at outlet overpressure and low temperature, automatic cutting off and automatic alarm, etc., basically realizing automation, reducing the difficulty of operation to ensure the safety of people and equipment.
- Reduce investment costs; The skidded production mode makes the mass production of LNG station possible, and the mass production will greatly reduce the cost of the skidded equipment, including the acquisition cost of the component equipment, the saving cost of the material usage, the installation cost, etc., which saves the investment for the end user. At the same time, the installation mode of skid mounting greatly saves the installation cost.
- Shorten the construction period; Skid-mounted equipment will reduce the amount of installation on site and greatly shorten the project construction cycle. The installation cycle is shorter, about half the time.
- Easy to install; The systematic design of the skid-mounted gasification station will make the on-site installation and alignment of each skid-mounted equipment module very simple.
- Simple operation; The controllability of the design and production of the skid installation equipment can fully simplify its operating procedures. Conducive to operation.
