We have two series of nitrogen plants to meet the different need of product nitrogen

The first type works on traditional process of back-flow expansion and single stage rectification .With this process ,the gas nitrogen and liquid nitrogen usually get a high pressure (0.5-0.9MPa) and large output.

The second type works on our exclusive process of back-flow expansion and double stages rectification .With this process, the nitrogen gets a high recovery ratio up to 75% and low power consumption. The gas nitrogen pressure usually gets 0.15~0.25MPa; and liquid nitrogen pressure gets 0.5~0.8MPa.This process could also produce two kinds of gas nitrogen with different
pressure,i.e.0.6-0.9MPa and 0.15-0.25MPa.
