Nitrogen Air Separation Unit

We’re launching a new project with two 5400m³ cryogenic flat bottom tanks. They’ll store large quantities of Liquid Oxygen (LOX) and Liquid Nitrogen (LIN). A nitrogen air separation unit in the vicinity of the project will provide this gas.

Nitrogen air separation units segregate atmospheric air into primary components through cryogenic distillation. This separates oxygen, nitrogen and other components naturally occurring in the air around us. The gases obtained are stored in liquid form to reduce their size so larger quantities of these gases can be moved on tanker trucks to consumers.

The advantage of air separation unit:

Remaining between the advantages and disadvantages of cryogenic method, pressure swing adsorption method and membrane separation method, the separation method combining the two is often used.

For example, the low-temperature method and the membrane separation method are organically combined to reduce production costs, increase oxygen production efficiency, and increase the output and purity of gas products to adapt to multiple uses of gas.

For example, the membrane separation method and the cryogenic method are combined to separate hydrogen and hydrocarbons from the dry gas of catalytic cracking. The membrane separation method is used to recover most of the hydrogen in the dry gas to enrich the remaining components in the dry gas. The dew point of the top gas of the demethanizer is increased, and the energy consumption and ethylene loss of the demethanizer are reduced. The combined process is particularly suitable for large-scale refineries with low-temperature separation devices that are short of hydrogen resources, and plays a great role in economic development.
