1．air separation plant

In an area or a region，According to different situation that consisting of at least have Oxygen generator station、Oxygen filling station and Oxygen compressor Station or any other building or construction which to be generally called air separation plant。

2．air separation station

Mainly on product oxygen or ASU product equipment，Including mainly or assist production building
3．oxygen filling station

Mainly on filling , store and delivery or only compress oxygen and delivery or any other ASU product equipment，Including mainly or assist production building

OXYGEN

Oxygen, or O2, which comprises 21 percent of the earth's atmosphere, supports life and makes combustion possible. The most abundant of all elements on earth, oxygen comprises 85 percent of its oceans and, as a component of most rocks and minerals, 46 percent of its solid crust. In addition, it constitutes 60 percent of the human body.
Colorless, odorless and tasteless, oxygen has poor solubility in water. A specific gravity of 1.105 makes it slightly heavier than air. When cooled to its boiling point of -297o F (-183o C), oxygen becomes a transparent, pale blue liquid that is sligh

oxygen cylinder filling according to different sources, there are two methods

No.1.First is that the source of oxygen from air separation plants for gaseous oxygen, used  pressurized oxygen compressor compresse oxygen  to 16.5Mpa, then by oxygen collecting bar to oxygen cylinder

No.2. the oxygen source is liquid oxygen from air separation plant, you can use liquid oxygen pumps for liquid oxygen and pressurized to 16.5Mpa, high-pressure liquid oxygen through the carburetor, liquid oxygen into high pressure gaseous oxygen, then by oxygen collecting bar to oxygen cylinder

The uses of liquid nitrogen

Liquid nitrogen is a compact and readily transported source of nitrogen gas without pressurization. Further, its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications, primarily as an open-cyclerefrigerant, including:
•in cryotherapy for removing unsightly or potentially malignant skin lesions such as warts andactinic keratosis
•to store cells at low temperature for laboratory work
•in cryogenics
•in a Cryophorus to demonstrate rapid freezing by evaporation
•as a backup nitrogen sourc

The effects of nitrogen
-Nitrogen gas  come from cryogenic nitrogen plant
1、as the preparation of nitrogen fertilizer raw materials
2、the nitrogen filled packaging, nitrogen filling bulbs (using chemical "chemical properties is very stable, normal temperature is difficult and other material reaction")
3、as a protective gas
4、synthetic dyes
5、The manufacture of explosives (5, 2, 3, 4 "by chemical properties at high temperature, high energy conditions and some chemical reaction")

Air separation plant can separate air into an oxygen/nitrogen and argon，And the oxygen / nitrogen gas and argon gas through the pipeline to the user or other ways to store.

Oxygen can be used in industries such as steel cutting, oxygen-enriched combustion, medical oxygen, petrochemical engineering, electric stove steel making, glass industry, papermaking, ozone generation, aquaculture and aerospace. According to requirements for oxygen of different customers, Henan Kenuo Energy Plant Co., Ltd.can provide individual and professional oxygen generators in order to meet different needs.

Our Company specializes in manufacturing LNG liquefaction plant.

The air separation plant with oxygen output ＞1000 Nm3/h can extract argon.

A: Start-up time:
The start-up time (from start-up of expander to up-to-standard of oxygen purity) is about 48 hours.
The start-up time to generate oxygen after temporary stop:
8 hours after temporary stop: 4-6 hours
24 hours after temporary stop: 8-10 hours
The time needed to discharge liquid from cold box (cooling tower and condenser) is about 8 hours.
The time of defrosting of cold box is about 36 hours.
The required time of load variation:
From full load to 90% load or otherwise: 1 hour
From 90% load to 75% load or otherwise: 2-3 hours
