We are one of the well-known industrial gas plant engineering companies in U.A.E free zone Jebel Ali with OEM factory in China which is reputed for manufacturing & fabricating BIU HANGZHOU BRAND nitrogen plant and oxygen plant which are able to generate oxygen and nitrogen in both gaseous and liquid form. The latest cryogenic distillation technology is used in the fabricating of all of our world-class plant machinery. Chinese manufacturing is not only known for their skills in building their machinery at quick pace but also for the incredible prices never losing the sight of the quality of the machinery. Our large capacity oxygen nitrogen plant can generate oxygen/nitrogen up to 20,000m3/hour. Moreover, it can generate oxygen/nitrogen with purity up to 99.7% and 99.9995% PPM, which is considered excellent for both medical process and industrial applications.

LARGE CAPACITY PLANT INNER VIEW
Process Description
- Air compressors -- The air will be compressed by it until O.5MPa-O.7MPa
- Pre-cooling unit -- The air will be pre-cooled by this unit untiI 5°C-1 O°C, and water shall be separated from the air.
- Purification -- The residual water, carbon dioxide and hydrocarbon will be separated from the air in this purifier.
- Air expansion -- The air will be expanded in this expander and produces the cold for the process.
- Air Cooling -- The air will be cooled by the counter-flowing gaseous oxygen ,gaseous nitrogen and waste nitrogen in the main heat exchanger of the rectification column until liquefing temperature of the air.
- After-cooling -- The liquid air and liquid nitrogen are after-cooled by the gaseous nitrogen before their being throttled.
- Rectification -- The air is rectified and separated in the rectification column.Thus the product gaseous nitrogen will be gained from the top of upper column and the product gaseous oxygen will be gained at the bottom of upper column.

- For cylinder filling we have to add a oxygen filling compressor in the pipeline to compress the oxygen/nitrogen coming out of the cold box at .5 t0 15 mpa as required by the process.
- For pipeline supply for steel plants the oxygen pressure coming out of the cold box has to be raised from 0.04 mpa to 0.15 to 0.3 mpa depend if we have to store in a oxygen gas buffer tank.
- KDON plant is very suitable for steel plants where oxygen gas is required at 10 to 15 bar.
- KDON means OXYGEN GAS + NITROGEN GAS.
- Nitrogen gas is a by product in this plant and is available simultaneously together with the oxygen.
