Commercial-grade sulphuric acid is inexpensive but often generated in a dilute or contaminated form that limits its reuse and market value.
Neutralizing such acid with lime leads to solid waste (calcium sulphate) handling issues and increases operational costs.
To address these challenges, Goel Impex provides complete design and engineering solutions for sulphuric acid concentration systems. These systems recover dilute acid and reconcentrate it to the required strength, allowing industries to reuse it efficiently. This approach not only eliminates disposal problems but also reduces the consumption of fresh sulphuric acid.
The process is straightforward and involves the concentration of dilute sulphuric acid through evaporation under a controlled vacuum. Steam or thermic fluid is used as the heating medium. The feed acid is first preheated and then passed through multiple evaporation stages to achieve the target concentration.
The vapors generated during the process are condensed and discharged via barometric legs, while non-condensable gases are removed using an ejector. The concentrated acid is then cooled and collected in a storage vessel for reuse.
The utilities required such as steam or thermic fluid, cooling water, and electrical power depend on parameters like feed rate, initial concentration, and final concentration desired.
For instance, in a 50 TPD plant processing a 50% Hâ‚‚SOâ‚„ feed to achieve 70% concentration, the utility consumption is determined based on these operational variables.
| 1 | Steam@ 6 bar{g) pressure | : 800 Kg/hr |
| 2 | Cooling water @ 30 째C | : 70 Cu M/hr |
| 3 | Power | : 15 KW |
