Chemical Dosing / Injection Packages

Chemical Dosing Injection Packages

Chemical Dosing / Injection Packages

Chemical dosing packages are among the most critical control subsystems in industrial processes. They play a direct and decisive role in maintaining equipment stability, controlling chemical process parameters, and reducing operational risks. These packages are designed for precise, continuous, and controllable injection of chemicals into fluid streams, and are widely applied across oil & gas, petrochemical, refinery, power generation, water & wastewater, and advanced chemical industries.

At Atieh Pardazan Sharif Holding, the design of chemical injection packages is based on a deep understanding of the process, real operating conditions, and safety requirements. Before detailed design, each package is engineered considering factors such as chemical type, required injection flow rate, injection line pressure, operating temperature, duty cycle, and site environmental conditions to ensure optimal performance tailored to the project’s needs.

Process Packages

Engineering Design & Equipment Selection

The selection of critical equipment in chemical injection packages is performed with high precision, as any error can lead to inaccurate dosing, premature equipment failure, or safety hazards. Engineering design includes hydraulic calculations, material compatibility, chemical resistance, and safety margins to ensure stable operation under all conditions.

Chemical storage tanks are selected based on the corrosive, toxic, or sensitive nature of the chemicals, using materials such as stainless steel, carbon steel with specialized coatings, polyethylene, polypropylene, or FRP. Tanks are designed for operational durability, ease of inspection, cleaning, and safe maintenance.

Pumping & Injection Control Systems

The pumping section is the heart of the chemical dosing package. High-precision dosing pumps—diaphragm, piston, or solenoid types—are chosen based on required flow rate and pressure. These pumps provide accurate dosing and support continuous or batch injection modes.

The injection control system interfaces with analog and digital signals from instrumentation or upstream control systems such as PLC or DCS, allowing automatic adjustment of chemical dosing in response to process variations. This prevents under- or over-dosing and ensures process efficiency and safety.

Safety, Protection & Reliability

Safety is a core principle in Atieh Pardazan Sharif’s chemical dosing package design. Safety valves, backpressure valves, pulsation dampeners, pressure protection devices, and emergency shutdown systems ensure safe operation even under unstable conditions.

Injection lines and nozzles are designed to prevent backflow, cavitation, crystallization, or blockages, enhancing downstream equipment life and reducing unplanned downtime.

Process Applications & Operational Benefits

Chemical dosing packages are used for a wide range of industrial applications:

Corrosion inhibitors
Scale inhibitors
Biocides
Oxygen scavengers
Coagulants and water quality modifiers

High dosing accuracy optimizes chemical consumption, reducing operational costs and environmental impact. Modular design allows future capacity expansion, adding new injection lines or upgrading control systems without major structural modifications.

Testing, Commissioning & Technical Support

All chemical dosing packages undergo full Factory Acceptance Testing (FAT) before delivery, verifying equipment performance, control system functionality, and safety. On-site commissioning includes Site Acceptance Testing (SAT) and operator training to ensure safe, efficient, and reliable operation.
