Project objective
Obtain comparable data on different ores, acid consumption, phosphorus transfer to the product and filterability of the gypsum by-product.
Offered technologies / Process plants
Pilot unit for wet-process phosphoric acid
A modular pilot line for comparing phosphate feedstocks and evaluating their processability. The concept links grinding, homogenisation, sulphuric-acid digestion, filtration and test-data assessment.
Operating context
The whole application matters.
The proposed skid contains a mill, homogenisation tank, agitated reactor and vacuum filter. Adjustable acid dosing, temperature and residence time enable different test conditions. pH, temperature and composition measurements are linked to the controls and recorded in a standard test report.
Scope of the solution
- Feed preparation and homogenisation, an agitated reactor and chemical pumps.
- Vacuum filtration separating acid filtrate from gypsum cake.
- PLC with HMI, operating-data logging and proposed XRF analysis.
- Frame, drip trays, piping and valves, with basic operating and test documentation.
Engineering priorities
From operating need to design.
Supply interfaces
Representative ore samples, particle size and analyses of P₂O₅ and accompanying impurities.
Engineering output
PFDs, P&IDs, equipment list and instrumentation database.
Before engineering
Inputs that matter.
- Which ores and composition ranges should be compared?
- Which test conditions and analytical outputs are required?
- Should the pilot cover digestion and filtration only, or further acid treatment as well?
- What requirements apply to relocation, utilities and disposal of by-product streams?
Agreed with the proposal
Outputs and acceptance.
- PFDs, P&IDs, equipment list and instrumentation database.
- Operating and maintenance manual, test-report template and acceptance-test plan.
- Proposed FAT, feedstock validation and SAT, installation supervision and operator training.
The actual scope and acceptance criteria depend on the application and contract.
