Acid and alkali dosing
Controlled injection for pH adjustment, neutralisation and process conditioning, with materials selected against concentration and temperature.
Petrox EngineeringCorrosive and critical process duties
Process Pumps & Chemical Dosing Systems for Chemical and Petrochemical Plants
Petrox Engineering supports corrosive chemical dosing, additive injection, transfer and mixing duties with application review covering fluid chemistry, containment, pressure, materials and plant integration.
Applications
Where Petrox supports chemical and petrochemical plants
Catalyst and additive injection
Repeatable low-flow metering where accuracy, turndown, stable back pressure and documented settings affect process consistency.
Corrosion-inhibitor dosing
Continuous or flow-paced chemical injection packages with duty/standby pumps, relief protection, calibration and instrumentation.
Chemical transfer and recirculation
Centrifugal, screw and other process-pump configurations selected around viscosity, solids, vapour behaviour and containment.
Tank mixing and solution preparation
Industrial agitators for dissolving, blending, suspension and preparation duties, matched to vessel geometry and fluid behaviour.
Skid-mounted dosing packages
Integrated tanks, pumps, valves, piping, instruments and controls engineered around project interfaces and inspection requirements.

Frequently asked questions
Technical questions from project teams
How are wetted materials selected for corrosive chemicals?
Selection considers the exact chemical, concentration, temperature, contaminants, pressure and mechanical design of every wetted component. Written compatibility confirmation may be required for severe duties.
Can Petrox support project documentation and inspection?
Yes. Scope can include technical submittals, approved datasheets, quality plans, inspection coordination and final documentation according to the agreed project requirement.
