Main Features of Air Separation Unit, Gas Plant-Liquid Oxygen Plant:
This development and design of flow is new, and my company uses the technology to mature.
2. Simple operation, convenient maintenance, short starting time, and low unit power consumption.
3. Oxygen of high purity and very stability meets and exceeds technical indicators of GB8982-1998<<medical oxygen>>
4. Using air cooling equipment does not need cooling water adaptable, saving costs.
5. Security: The outside compression process is oxygen being compressed at room temperature, and The inside compression process is liquid oxygen being compressed at a low temperature, Security than more with the inside compression process; Extraction of 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 has excellent performance, easy to maintain; the Booster compressor is one or two compressions, and the oxygen compressor Booster compressor is three or five compressions, High reliability of the booster compressor.

The equipment of the cryogenic air separation Unit:

(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 the automatic cleaning of the filter element.

(2)Air Compressor
Atlas copco、Hanwa(Samsung)
The air compressor adopts an 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.

(3)Air pre-cooler
The air pre-cooler condenses the gaseous water in the compressed air into droplets using cooling and then separates the gas and liquid through the separator, And the outlet temperature is controlled at 5℃ ~10℃,
The main components adopt international brands, such as Germany Bizer, Denmark Danfoss, America Emerson, etc.
We use Siemens PLC control and can use RS485 I/O, Profibus, and Modbus communication types.

(4)MS Purifier
The two adsorption vessels in the purification system work alternately. When one plate is in the adsorption cycle, the other boat is in the regeneration cycle. The exhaust gas of the equipment is regenerated. Siemens PLC’s control system controls this technological process.
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 provide air and molecular sieve contact time and ensure the adsorption effect. The new airflow distribution structure ensures uniform air distribution and avoids the 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 channels 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 an 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 exchangers has high heat transfer efficiency with slight and minor temperature differences, effectively reducing 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 tube box and cut off the wt air to ensure the insulation effect hard the cold box and reduces heat loss, and further reduces energy consumption

Turbine expanders can be divided into gas-bearing and oil-bearing, with a small refrigerating capacity using gas-bearing and a sizeable refrigerating power using oil-bearing.
The working wheel press is precision machined with an 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 average expected temperature end without needing to pick up pearlescent, which is convenient maintenance; the Oil bearing expander adopts an adjustable nozzle to adjust the cooling cap. city A double oil pump is set; One for use and one for backup, automatic switching use in operation(Oil bearing expander)

(8)Control system
The instrument control systems should be able to effectively monitor sets of air separation equipment production processes to ensure reliable running, convenient operation, and maintenance. Adopt centralized monitoring control and the principle of combining in situ monitoring and control.
To adapt to the needs of the technological process, the instrument control system adopts the Siemens PLC control, the team, the main process parameters trend display, records, historical records, control, alarm, print, tables, and flow chart of the picture shown performed by Siemens PLC system.
The central control room uses a 23-inch color LCD monitor. It has a multifunction printer for operation print, alarm printing, and tabulation PLC completes expander and interlock protection systems of all kinds of pumps and motors by PLC. It can memory, display, and alarm when the relevant process parameters are over the limit. The interlock protection will be according to the technological requirements, automatic start or stop, open or close the e valve and manual operation can be achieved to open and control the equipment.
