Ethanol Blending Solutions

Modern terminal operations increasingly rely on advanced ratio blending systems to ensure accuracy, regulatory compliance, and operational efficiency in ethanol blending. These systems use electronic presets to control both gasoline and ethanol meters and valves simultaneously, enabling precise real-time ratio blending.

For new facilities, rack setups typically include a Positive Displacement (PD) flow meter and control valve for both the gasoline and ethanol streams. Gasoline lines commonly feature a 4” turbine or PD meter with a 4” valve, while ethanol lines utilize a 2” meter and valve. The electronic preset synchronizes both flow paths, metering each fluid accurately and blending them in-line into the loading arm and directly into the truck.  All flow data is recorded and integrated with both the Terminal Management and Inventory System.

For existing terminals, a practical and less invasive alternative is the installation of off-rack ethanol blending systems. These inject ethanol upstream of the loading rack, requiring minimal infrastructure modifications. A proven approach is the use of modular blender skids—preassembled, factory-tested units designed for quick deployment integrated with existing preset system. Each skid includes dedicated PD meters and hydraulically actuated valves, allowing independent control of ethanol injection for each gasoline arm to ensure coordinated flow and metering of both components. These systems also integrate seamlessly with the Terminal Management System (TMS), transmitting accurate ethanol and gasoline volumes per load for effective inventory management and quality assurance.
