Additive Injection Systems
Excel Loading Systems designs and fabricates custom additive injection systems for petroleum terminals, fuel distribution facilities, renewable fuel plants, chemical processors, and industrial manufacturing operations. Our skid-mounted additive injection systems provide accurate, repeatable dosing of performance additives, dyes, lubricity enhancers, detergents, corrosion inhibitors, and specialty chemicals into product streams.
Each system is engineered to your specific flow rates, chemical compatibility requirements, control strategies, and operational objectives.
What Is an Additive Injection System?
An additive injection system is a precision dosing package designed to introduce small quantities of chemicals into a primary product stream. These systems ensure consistent product quality by accurately controlling additive volumes regardless of changing flow conditions.
Common applications include:
- Fuel additives
- Biodiesel additives
- Renewable diesel additives
- Corrosion inhibitors
- Lubricity improvers
- Conductivity additives
- Detergents
- Marker dyes
- Product tracers
Fuel Terminal Applications
Additive injection systems are commonly installed at fuel terminals where multiple products are loaded through a common loading rack.
Detergent Packages
Used in gasoline blending to improve engine cleanliness and fuel performance.
Lubricity Additives
Frequently injected into ultra-low sulfur diesel fuel.
Conductivity Improvers
Used to reduce static electricity concerns during loading operations.
Cold Flow Improvers
Designed to improve fuel performance in low-temperature environments.
Marker Dyes
Used to identify product grades and support regulatory compliance.
Renewable Fuel Applications
Renewable fuel facilities often require precise additive injection to maintain product quality and performance across renewable diesel, biodiesel, ethanol, and sustainable aviation fuel (SAF). Available systems can be configured for single additive injection, multiple additive injection, automated recipe control, and batch blending.
System Components
- Metering pumps — Positive displacement, diaphragm, gear, and peristaltic pumps, selected based on chemical compatibility, flow requirements, viscosity, and operating pressure
- Storage tanks — Day tanks, bulk additive tanks, double-wall tanks, stainless steel tanks, and polyethylene tanks
- Flow measurement — Coriolis, positive displacement, turbine, and magnetic flow meters for additive accuracy and traceability
- Controls and automation — PLC controls, HMI operator interfaces, recipe management, automated batch control, SCADA integration, and remote monitoring
Multi-Additive Systems
Many facilities require multiple additives injected into the same product stream. Excel Loading Systems designs systems capable of simultaneous injection, sequential injection, product-specific recipes, and automated product selection — allowing operators to efficiently manage multiple products from a single loading rack.
Benefits of Additive Injection Systems
- Improved product quality — Precise dosing improves consistency and product performance.
- Reduced chemical consumption — Accurate injection reduces waste and unnecessary additive usage.
- Automated operation — Control systems reduce operator involvement and improve repeatability.
- Faster loading operations — Integrated systems support efficient terminal throughput.
- Regulatory compliance — Proper additive control supports product specifications and regulatory requirements.
