Production Process and Technical Characteristics of Flake Vanadium Pentoxide via the Two-Step Method

The two-step process for producing flaky vanadium pentoxide is straightforward, fully demonstrating its advantages of low capital investment in process equipment, efficient thermal energy utilization, and high recovery rates.

Process flow:

Technical features:

Used for melting and preparing pellets of ammonium metavanadate, to produce flaky vanadium(V) oxide.

Production capacity is aligned with the company’s needs, G=5t/d ~ 24t/d or higher;

Wide fuel compatibility: coal, coal gas, natural gas, fuel oil, and more.

It can melt under low-temperature conditions, t=850 °C ~ 900 ℃; the molten flue gas is directly used for the drying and pre-decomposition of ammonium poly(vanadate), resulting in high thermal energy utilization.

The system is easy to operate and has a low failure rate.

System total High recovery rate, η≥ 98.5 ~ 99% , environmentally friendly production.

Key Economic and Technical Indicators

Reduce the total equipment investment amount One third ~ 1/2 (Compared with the three-step method);

High recovery rate, η≥ 98.5 ~ 99%；

Low energy consumption: θ≈ 240kgce/tV₂ O ₅
