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.
