Main Features of Air Separation machine , Air Separation equipment ,Gas Plant-Liquid Oxygen Plant:

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. 

We mainly exported to many countries such as Egypt, Thailand, Vietnam, Bangladesh, Indonisia ,Angola, Korea, Uzbekistan etc.Mainly we provide below equipments:

Main equipment of our oxygen pant :

1. Self-cleaning air filter

It is a mechanical and electrical integration equipment, the automatic realization of air filtration and filtration components of the automatic cleaning. The air filter operates as usual during automatic cleaning of the filter element.

1. Air Compressor

Atlas copco,Hanwa(Samsung)
The air compressor adopts oil-free centrifugal type, which compresses the raw air to the pressure required by the process. The brand is internationally renowned, such as Atlas copco, Ingersoll rand, etc.

 

1. Air pre-cooler

The air pre-cooler condenses the gaseous water in the compressed air into droplets by means of cooling, and then separates the gas and liquid through the separator, And the outlet temperature is controlled at 5ºC ~10ºC, The main components adopt international brands, such as Germany bizer, Denmark , America Emerson, etc.
We use Siemens PLC controal,can use RS485 I/O, Profibus, Modbus communication type.
 

1. MS Purifier

The two adsorption vessels in the purification system work alternately. When one vessel is in the adsorption cycle, the other vessel is in the regeneration cycle. The exhaust gas of the equipment is regenerated. This technological process is controlled by Siemens PLC control system.
The new UOP molecular sieve is selected to ensure the adsorption effect of water, carbon dioxide and hydrocarbons, lower regeneration temperature, energy saving and consumption reduction.Rigorous design to ensure air and molecular sieve contact time, ensure the adsorption effect. New airflow distribution structure ensures uniform air distribution and avoids tunneling effect. Heat preservation materials are used for heat insulation of the heater barrel and some pipelines of the adsorber to reduce energy consumption. Heat preservation materials are used for heat insulation of the heater barrel and some pipelines of the adsorber to reduce energy consumption
(5) Distillation column
The fractionator is the core of the equipment, where the required products are made.
It is excellent design, and process simulation calculation, optimization to ensure that the design parameters of advanced and reasonable
With the international advanced low temperature rectification technology, the energy consumption index of our company can keep up with the international advanced level
Adopting vacuum brazing aluminum plate-fin heat exchanger has high heat transfer efficiency and small temperature difference, which can effectively reduce cooling loss and energy consumption. Design the structure and stress analysis to ensure the safety and reliability of the cold box 
The cold box sealing air valve is installed, and the waste gas is used to inflate the cold box and cut off the wet air, so as to ensure the insulation effect of the cold box and reduce heat loss and further reduce energy consumption
 

1. Turbo-expander

Turbine expander can be divided into gas bearing and oil bearing, small refrigerating capacity using gas bearing, large refrigerating capacity using oil bearing.
The working wheel press is precision machined with advanced five-axis CNC milling machine to ensure the machining accuracy of the impeller profile and high expansion efficiency.The rotor and bearing can be directly replaced from the normal temperature end, without the need to pick up pearlescent sand, convenient maintenance;Oil bearing expander adopts adjustable nozzle to adjust cooling capacity A double oil pump is set;One for use and one for backup, automatic switching use in operation(Oil bearing expander)

1. Control system 

Instrument control system should be able to effectively monitor sets of air separation equipment production process, to ensure the reliable running, convenient operation and maintenance. Adopt centralized monitoring control and the principle of combining in situ monitoring and control.
In order to adapt to the needs of the technological process, instrument control system adopts Siemens PLC control system, the main process parameters trend display, records, historical records, control, alarm, print, tables, and flow chart of the picture show performed by Siemens PLC system.
The central control room uses 23 inch color LCD monitor,and have the multifunction printer for operation print, alarm print, tabulation print.
Expander, and interlock protection system of all kinds of pump and motor are completed by PLC. It can memory, display and alarm when the relevant process parameters are over the limited. The interlock protection will be according to the technological requirements, automatic start or stop, open or close the valve, and manual operation can be achieved to open and stop the equipment.
