Vpsa Industrial Oxygen Plant Unit - China

Technology Brief:

Vacuum Pressure Swing Adsorption (VPSA) is an advanced gas separation technology that utilizes the different selectivity of adsorbents for gas molecules to separate gas components.

Based on the principle of VPSA technology, the VPSA-O2 units adopt the special adsorbent (model: PU-8) to enrich the oxygen in the air and supply it to the user.

Production Capacity

1000Nm3/h~40000 Nm3/h, Converted to liquid oxygen: 34 TPD~1360 TPD

Typical Applications

> Steel: Blast furnace oxygen-rich coal injection, electric furnace steelmaking

> Non-ferrous metallurgy: combustion-supporting for non-ferrous metals metallurgy including copper, lead, nickel, zinc, tin and gold.

> Chemical: gasification furnace oxygen-rich gas making, carbon black production, sulphur trioxide production etc.

> Kiln energy-saving: combustion supporting for glass kilns, cement kilns and oxygen-rich combustion supporting for waste incinerators > Papermaking: pulp bleaching process

> Sewage treatment: OEAA technology, oxygen source for ozonizer

Technical Advantages

Based on the high-efficient lithium-based VPSA-O2adsorbent PU-8, combining with the unique airflow distribution technology, advanced process design and reliable supplementary devices, PIONEER has successfully ensured energy-efficient and large-scale VPSA-O2plants to provide O2product at a lower cost.

PIONEER has built up over 100 sets of VPSA-O2plants and taken the lion share in the field of VPSA-O2in China.

The VPSA-O2technology won the first prize for Science and Technology Progress by the Ministry of Education.

1 - Experienced engineering

PIONEER has built the most VPSA-O2 plants in China, including the world’s largest VPSA-O2 plant.

2 - Excellent energy consumption

Energy consumption of PIONEER’s VPSA-O2 plant is <0.35 kWh/m3 O2, which is among the lowest, around the world .

3 - Internationally-leading process design

PIONEER has built up the first set of radial bed in China.

Independently-devel oped five-bed, air intake and other original process designs have proved obvious advantages.

4 - The independently-developed lithium-based adsorbent

PIONEER’s independently-developed and produced lithium-based VPSA-O2 adsorbent PU-8 is featured by high selectivity and high working capacity of nitrogen, which is among the best around the world.

5 - Mature and reliable system running

The long-term engineering practice has proved that PIONEER’s VPSA-O2 plants are stable and the supplementary devices are mature and reliable, thus ensuring the continuous production for users.

PIONEER is committed to mutual development with the customers, by providing economical O2utilization program, optimization of existing plants or on-site gas supply.

Technical Principle

The VPSA-O2 after desorption is blown by a blower and enters the adsorption vessel of the VPSA-O2 system after being filtered and removed mechanical impurities.

The adsorber is a double-vessel system, and its product is oxygen.

Nitrogen, carbon dioxide and water vapor in the air are adsorbed, and a vacuum pump will be applied after saturated adsorption to ensure the adsorbents in the adsorption vessel are completely desorbed for regeneration.

The double-vessel VPSA-O2 system ensures continuous oxygen generation through cyclic switch of the program control valve under the control of PLC (data control system).
