Output, purity and pressure

Description:

1. This plant employs a process in which the air is purified by molecular sieve, expansion turbine is provided with braking effected by fan and nitrogen is produced by means of single column with expansion accomplished through backflow.
2. A small part of purified process air is drawn out to be used as instrument air and the remainder is fed into main heat exchanger. The expanded waste nitrogen is drawn, which cooled after being expanded to a saturation temperature and moisture- bearing to a certain extent, is throttled into the bottom of nitrogen column for participation in rectification. The nitrogen gas and liquid nitrogen are then obtained at the top of nitrogen column while the saturated and oxygen-rich liquid air at the bottom of column is throttled into the evaporation side of condenser evaporator to condense the nitrogen gas at the top of column.
3. Oxygen-rich liquid air at the evaporation side of condenser evaporator is heated and evaporated to be saturated gas by nitrogen gas at the top of column, and then it is drawn out and into cold end of main heat exchanger after being re-warmed, it is drawn out and into turbo-expander to be expanded and refrigerated.
4. Expanded oxygen-rich liquid air enters main heat exchanger to be re-warmed to normal temperature and to be fed out of cold box; partial gas is to be regeneration gas for molecular sieve adsorber, partial gas is sent to the user, and the rest is blown off.
5. The nitrogen gas and liquid nitrogen are drawn out of the top of nitrogen column. The nitrogen gas flows out of cold box to the client after it is reheated in main heat exchanger to a normal temperature.

Applications:

• Pulp & Paper
• N2 Converter Rental
• Depth refrigerant
• Food industry
• Pharmaceutical and biotechnology

Competitive Advantage:

1. Our company has a high market share in China

2. Perfect technology R&D system

3. The advanced software introduced from abroad for calculation of performance is used to analyze the optimization of process adopted by this plant. The more advanced program developed by Hangyang itself on the basis of rectification design module from Linde for rectification calculation and verified in many air separation plants is applied to ensure the price proportion of optimum technical/economical figures to fine performance.
