LNG is a high-quality, efficient and clean energy source. LNG can be stored and transported safely and conveniently like oil. The development of LNG technology has increased the competitiveness of natural gas in the world. As an "environmentally friendly" energy source, the status of natural gas is increasing and the market prospect is very broad. LNG engines emit only 25% of the nitrogen oxides emitted by diesel engines. Hydrocarbons and carbon oxides are only 30% and 12% of diesel engines respectively. The emissions of particulate matter are almost zero, and the sound power of LNG engines is only diesel engines. 36%; using LNG as a fuel for automobiles, the nitrogen dioxide and carbon dioxide in the exhaust gas are 98% and 30% lower than that of fuel oil, which is more environmentally friendly.
Our Machineries For Producing LNG Cylincer
We are the world's leading supplier of LNG cylinder production lines, providing all aspects of LNG cylinder production. Safety, environmental protection, high quality, high efficiency and low labor are our advantages. LNG cylinders produced with our machines can be kept at 190 degrees Celsius for up to 12 months. Currently, LNG cylinders are mainly used for fuel storage in cars, trucks and city buses. It is foreseeable that with the development of LNG as a clean energy source, high-quality LNG cylinder production will usher in a broad market.
