Solution advantages |
|
The process organization is advanced and reasonable, which not only can run stably for a long time, but also has a large amount of liquefaction and low energy consumption. It adopts pressurized turbine expander, which has small volume, few units, stability, safety, reliability and high efficiency, so it has high liquefaction rate and less energy consumption per unit. Adopt circulating compressor, with small volume, few units, stable, safe and reliable, high efficiency and less energy consumption per unit. It adopts aluminum plate heat exchanger with high heat exchange efficiency, small volume and light weight. The cold box piping, Valve and primary measurement and control components of the liquefaction unit are all made in the factory. After passing the pressure test and leak test, they will be delivered as a whole, which is convenient to transport and easy to install. |
