The operating cycle of the VPSA oxygen production process is very short, generally less than 1 min. In one cycle, each adsorption vessel needs to experience the steps of adsorption, pressure reduction, desorption, purging, even pressure increasing, etc. Key valves switch on and off once in each cycle, which is pretty frequent, so they are required to be switched quite fast in order to impro...

VPSA oxygen plant suppliers usually provide overall materials including instructions for use, maintenance manuals and troubleshooting manuals. The structure of VPSA plant is simple- the rotary equipment only consists of a blower and a vacuum pump which are general-duty equipments with simple maintenance, therefore, maintenance of VPSA oxygen plant is generally composed of two parts: i...

The VPSA oxygen generation plant is characterized by its short operating cycle (generally only tens of seconds), so the exhaust pressure of blower will change rapidly with large fluctuation ranges during operation. Based on the principle of vacuum pressure swing adsorption, the blower is required to satisfy the stability of gas volume under the circumstance, which is the essential condition ...

There are two ways to provide VPSA enriched oxygen to blast furnace: The First approach is oxygen enrichment after the blower, i.e., the low-pressure oxygen at the outlet of VPSA oxygen plant is pressurized by an oxygen compressor to 6Bar(G), then mixed with ambient air in the cold air pipe at the blast furnace blower outlet to achieve enriched oxygen. The second one is oxygen inject...

The VPSA oxygen plant consists of power system, adsorption system, valve system, instrument control system, electronic control system and supporting public & auxiliary system, which are respectively described as follows: The power system, consisting of Roots blower, Roots vacuum pump, electric motor, air filter, silencer, elastic joint and other ancillary parts, works to provide the po...

Due to its low cost, flexible load adjustment, and simple start-up & shut-down, VPSA oxygen generation technology is widely used in industrial production. For example, in the steel industry whose market has improved in the past two years, in order to increase the oxygen enrichment rate of blast furnace, reduce the coke ratio and improve blast furnace production capacity, usually VPSA...

(1) Energy Saving The vertical adsorption vessel is a radial cylindrical-grid-structure vessel. Compared with the axial adsorption vessel, the adsorbent bed is thinner, and the resistance is smaller, thus reducing the air flow pressure and leading to the discharge pressure & power decrease of rotary equipment correspondingly. By calculation and practice, energy consumption of VPSA oxy...

At present, industrial oxygen production methods mainly include cryogenic air separation oxygen generation, pressure swing adsorption oxygen production and membrane separation oxygen production. Pressure swing adsorption is an advanced gas separation technology standing at an irreplaceable position in the field of onsite gas supply in the world today. Main features of pressure swing adsorption ...

By the end of 2019, Pioneer’s annual turnover has reached ¥600 million as per the preliminary statistics on new projects this year, which will usher in a new historical breakthrough. Meanwhile, Pioneer still spares no effort in optimizing oxygen plant project management and improving engineering quality. On December 3, 2019, the Engineering Technology Department held the sixth Project ...

Compared with the cryogenic separation technology, PSA-CO plant has quite a few advantages: simple operation, short start-up and shut-down time, flexible load adjustment and high automation. It only takes tens of minutes to start up. Meanwhile, according to the downstream needs, load adjustment within the range of 30% to 100% can be realized by simple adjusting at short notice, which can g...
