WELLCARE Air separation plants are designed for a vast range of capacities and products summarized below: FOR OXYGEN 99.7 % AND NITROGEN 99.999%
Two compression methods:
1)Internal compression air separation plants:
Air-Compressed-Pre-cooling-Purifier-Rectification-heart exchanger (low pressure liquid)-Liquid oxygen pump(pressurized liquid oxygen)-oxygen vaporizer - oxygen cylinders
2)External compression air separation plants:
Air-Compressed-Precooling-Purifier-Rectification-heart exchanger (low pressure gas)-oxygen storage-oxygen compressor(pressurized oxygen)-oxygen cylinders
The main technical specifications of internal compression
Oxygen filling (or booster) with liquid pump.
The Plant uses normal temperature molecular sieve adsorption, medium pressure booster expansion reflux flow.
Raw air is sucked from the atmosphere,It is going through filter for removal of dust and mechanical impurities.,then it is compressed to a certain degree by single stage screw compressor,via end stage cooler, air pre-cooling system, the air is cooled to approx. 8ºC. After water separation moisture is separated in water separator and then it goes to purifier for removal of moisture, CO2, C2H2 and hydrogen dioxide.
Then most part of air enters main heat exchanger to be cooled to saturated tempt. and partly is liquefied to the lower part of lower column; another part of air is compressed to a certain degree through two stage compression booster, via end stage cooler enters into oxygen heat exchanger to be cooled to be near saturated temperature, then after throttle goes to lower column. Through lower column pre-distillation we can get enriched oxygen liquid air from the bottom of the column. After cooling through sub-cooler,after throttled it goes to the middle part of upper column as reflux liquid for rectification. WN is obtained from the top of lower column, after condensed through condenser-evaporator, a part of WN is used as rectification reflux liquid for lower column; another part after cooling through sub-cooler and after throttling goes to the top of upper column as rectification reflux liquid. Pure liquid oxygen is obtained from the bottom of upper column, and it is condensed by condenser-evaporator. Liquid oxygen is abstracted from the bottom after cooling through sub-cooler, then it goes to LOX pump to be pressurized. It is evaporated in O2 heat exchanger and is reheated to normal tempt and then directly goes to oxygen filling ramp for filling of cylinders.
WN from the top of upper column goes through sub-cooler, the ower part of main heat exchanger to be reheated to a certain tempt. Then it goes to expansion turbine to create cold and returns to sub-cooler and main heat exchanger again to be reheated to normal tempt. A part of it passes to purifier as regenerating gas resource and another part goes to be vented partly.
The main technical specifications of external compression
Oxygen filling(or booster)with oxygen compressor.
High production capacity, high purity, low power consumption, produce Nitrogen, Oxygen .
More choice in designation
As for the big production capacity and high purity, cryogenic air separation plant is now wide used in steel factory, food making, metal welding and cutting etc.
Our cryogenic air separation plants produce oxygen, nitrogen efficiently and safely every day.
How It Works
The process begins with the intake of huge volumes of air from the atmosphere. The air is compressed and purified before entering the cryogenic equipment package. The air is cooled to about -300° F (-185° C) and then, relying on different boiling points, separated into its elemental components in the form of liquid oxygen and nitrogen.
We help to design and manufacture Cryogenic air separation plant of production capacity from 50cbm ~ 2000 cbm.
WELLCARE cryogenic system components include:
An air filter
An air compressor
An air pre-purifier
An separation tower / insulated package containing cryogenic equipment (cold box)
A turbine expansion engine
we supplied to many countries (Peru, Pakistan, Russia, Kazakhstan, Tajikistan, India, Bangladesh, Thailand, Philippines, North Korea, Mongolia, Equatorial Guinea, Botswana, Zambia, Angola, Tanzania) .
1.This development and design of flow is new, my company use the technology to mature.
2.Simple operation, convenient maintenance, starting time is short, unit power consumption is low.
3.Oxygen of high purity and very stable, meet and exceed technical indicators of GB8982-1998<<medical oxygen>>
4. Use of air cooling equipment, do not need cooling water, adaptable, saving the cost.
5.Security :The outside compression process is oxygen be compressed at room temperature, The inside compression process is liquid oxygen be compressed at low temperature, Security than more with the inside compression process; Extraction a lot of liquid oxygen from evaporation-condenser, To ensure that no accumulation of hydrocarbons; Evaporation of high pressure with liquid oxygen, reducing the possibility of hydrocarbon accumulation; Reducing fire hazards.
6.Reliability: liquid oxygen pump excellent performance, easy to maintain; Booster compressor is one or two compression, oxygen compressor Booster compressor is three or five compression, High reliability with booster compressor.
