Description:


This plant employs an external compression process in which air is absorbed and purified by molecular sieve in completely low pressure, and air turbine boosting expander is used to produce refrigerating capacity. It has the advantages of reliable running, advance process and easy operation.

The process of this plant is decided after detailed analytical calculation with the classic physical property library, and the air separation physical property library software developed by Hangyang on the base of classic chart, process thermodynamic calculation software developed by Hangyang, American HYSYS thermodynamic calculation software, specialized air cooling and molecular sieve system performance and structure calculation software, American S-W company plate heat exchanger calculation software and American NREC turbo wheel design and process software.

The process design of this plant is according to the rich design and manufacture and installation operating experience of several middle and small ASP of Hangyang, which reflects the international advance design philosophy, and under the premise of guaranteeing the reliability of the plant, it also considers the reasonability, safety and advancement.

The important indexes to measure the performance advantage of ASP are oxygen production energy consumption and the extraction efficiency of oxygen. This ASP can guarantee the high rectifying column oxygen extraction efficiency, and at the same time the matched units have excellent single performance indexes to make sure the excellent combination performance indexes of the plant.

The static equipment lower column employs sieve plant column, and the upper column, crude argon column and pure argon column employ packing column.

The new efficient air pre-cooling system with water cooling tower is employed, which makes the most of the hygroscopicity of dry waste nitrogen and cooling water unit to reduce the temperature of cooling water.

The molecular sieve is designed as double-layer bed and long period, whose life is long, regeneration energy consumption is low ,and working condition is stable.

The features of the external compression equipments are fully considered during the process organization and design. Well design the start, adjust, normal and accident stop of the plant from the process organization and design angle to make sure the safety and reliability of the plant.



Applications:

  • Food refrigerating industry
  • Aerospace and aviation industry
  • Fertilizer Industry
  • Source of energy
  • Water and wastewater treatment
  • Welding and metal processing

Competitive Advantage:


The domestic advance pneumatic self-cleaning air filter is employed to clean the mechanical impurities and dust contented in the feed air.

Centrifugal compressor is employed to supply the pressured feed air.

The new efficient air pre-cooling system with water cooling tower is employed to cool and wash the feed air.

The system is designed for long-term operation, double-layer bed purification technology, and the switchover system employs impact-free switching control technology to adsorb the moisture, CO2, acetylene, propylene, propane, heavy hydrocarbon and N2O contented in the air.

The fractionating column system is the core system of this ASP, which is used to separate the oxygen and nitrogen contented in the feed air through cryogenic fractionation.

In order to make the main condenser evaporator with more safe & reliable running, Hangyang takes a series of measures of guaranteeing the safe running of main condenser evaporator in the design.

The booster expansion turbine is one of the core units of this plant, which is used to provide the refrigeration capacity needed by the plant. One for normal use and one for standby duty with reliable performance, effeicent & advance.
