LNG whole point solution

LNG-- liquefied natural gas (Liquefied Natural Gas, referred to as LNG) is recognized as the most clean energy on the earth. A colorless, tasteless, non-toxic and non corrosive, its volume is about the same amount of gaseous natural gas volume 1/600, liquefied natural gas's weight is only about 45% of the same volume of water. The manufacturing process is the first gas field production of natural gas purification treatment, liquefied under ultra-low temperature, the use of liquefied natural gas ship.

LNG is currently mainly used for city taxis, buses provide liquid or gaseous fuels. Compared with CNG, LNG has higher compression ratio, more easy to transport, while the gas purity and cleanliness is better. With the need of the implementation of the national clean energy policy and energy strategic reserve, the development prospect of LNG expansive.

Classification of LNG filling station:

Fixed type LNG filling station

Mainly used in filling in the 3~5 million M fand / day, filling quantity is big case of using such a filling station,
Covers an area of 5~7 acres, mainly used for heavy-duty trucks, filling more larger volume of vehicles or large city of intercity bus. 3~5 million M fand / day, standard fueling station main equipment according to double pump double liquid machine equipment configuration.

Skid mounted type LNG filling station

Flexible, less land occupation. Do not rely on natural gas pipeline network, only the LNG tanker carrying LNG as source. All process equipment in the station are mounted on a skid, small overall dimensions (length * width * height size is 12m * 2.5m * 3.31M); control system installed in a converted standard containers (size length * width * height is 6m * 2.5m * 3M); filling before LNG filling station the overall total quality is only 21.8t, very suitable for automobile transportation. Gas station location can be changed at any time according to the market demand, especially in the city proper.

Safety, environmental protection, low energy consumption. LNG has been purified, without compression, cooling, dehydration, desulfurization and the power consumption of the larger unit, the entire production process eliminates the need for natural gas purification equipment and air compressors, greatly reducing the facilities, not only saving the cost of the equipment, but also shorten the construction period.

A high degree of automation, easy operation. Equipped with automatic control system, data acquisition, the combustible gas monitoring, super pressure pump stop and low open pump process are done automatically, simple and easy to operate.

Mobile LNG refueling station

Mobile prizing station is mainly used for temporarily not conditions site conditions, the user request filling is more urgent, the use of the equipment.

Characteristic is that all devices are installed on the mobile car, strong maneuverability. The disadvantage is the storage capacity is relatively small, about 13~30m fand in storage tank.

LNG filling station working flow:

Low temperature pump unloading process: by LNG LNG LNC will be in the tanker unloading to the LNG storage tank.

Filling process: LNG LNG low temperature storage tank by a pump, filling to the car through the filling machine.

Pressure regulating process: after unloading, LNG low temperature pump from a tank out of some LNG to enter the tank through the LNG gasification regulator, when the tank pressure reaches the set pressure to stop the gasification.

To achieve the discharge liquid from the tank filling station, cryogenic storage tank on the lower liquid inlet; tank level protection system, leak proof system and automatic regulating system to realize the function of measurement; aerated aerated and quantitative filling function; automatic control system of pump can block three of variable frequency speed regulation, to realize the low speed circulating, filling and storage tank and motivated liquid function.
