Main Features of Nitrogen Plant
* This development and design of flow is new, my company use the technology to mature.
* Simple operation, convenient maintenance, starting time is short, unit power consumption is low.
* Use of air cooling equipment, do not need cooling water, adaptable, saving the cost.
*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.
* 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.
