Acid and alkali dosing
Metering systems for approved process, neutralisation and water-treatment chemicals with concentration-specific material review.
Petrox EngineeringAcids, alkalis and demanding process chemicals
Chemical Dosing Pumps for Fertilizer Plants
Petrox Engineering supports fertilizer-plant chemical dosing and transfer duties with VK Pumps metering technology, system integration and material selection based on actual concentration, temperature and pressure.
Applications
Where Petrox supports fertilizers
Antiscalant and inhibitor injection
Controlled chemical feed into water, cooling and process circuits, with calibration and stable back-pressure provisions.
Ammonia-related chemical service
Equipment selection for defined compatible liquid duties, subject to plant safety, containment and materials requirements.
Effluent-treatment chemicals
Coagulant, polymer, acid and caustic dosing for ETP and wastewater-treatment systems.
Viscous additive transfer
Screw-pump options for compatible viscous or shear-sensitive fluids where steady low-pulsation transfer is needed.
Chemical preparation and agitation
Tanks, agitators and pumps integrated for dissolving, blending and controlled chemical-feed packages.
Operating challenges
Requirements that shape the solution
- Strong acids, alkalis and corrosive contaminants
- Crystallisation, solids and scaling
- Elevated temperature and outdoor service
- Abrasion and erosion
- High plant availability
- Safe maintenance and spare-parts planning
Selection inputs
Information needed for selection
- 01Exact chemical composition and concentration
- 02Normal and upset temperature
- 03Solids, crystallisation and settling behaviour
- 04Required flow range and discharge pressure
- 05Wetted materials across the entire system
- 06Flushing, drainage and maintenance method

Frequently asked questions
Technical questions from project teams
Can one material specification cover every acid concentration?
No. Compatibility can change with concentration, temperature and contaminants. Every chemical duty requires confirmation against its complete operating range.
Can dosing skids be supplied with duty and standby pumps?
Yes. Redundancy, common equipment, isolation and changeover controls are defined around the plant availability requirement.
