Blending & Additization

In-tank or inline

In-tank blending is flexible and easy to verify: the tank is a closed batch that is mixed, sampled and certified. Inline blending saves tank time and handling, but depends on accurate meters and analyzers because the product is finished as it flows. We choose the method by product, batch size and how tightly the specification is drawn.

Recipes and records

Every blend starts with a written recipe: the components, their ratios, the property targets with tolerances and the tests that will confirm them. Component quantities are measured to custody standard going in, and the blend is measured coming out, so any volume gain or shrinkage is visible rather than buried in a loss account.

Additive and dye injection

Additives are dosed in parts per million, so small metering errors matter. Rack injectors dose each load by meter pulse, and in-tank treatment is dosed against measured tank volume. We verify injector calibration on a set routine and reconcile additive used against product delivered, so the owner can see that every load received its dose.

• Gasoline detergent packages at the brand rate, never below the EPA minimum
• Diesel lubricity, conductivity, cetane and cold-flow additives
• Red dye for untaxed diesel under IRS rules
• Antioxidants for biodiesel and other stability-sensitive products
• Proprietary packages supplied by the owner and dosed to their instructions

Laboratory verification

Testing proves the recipe worked. Tests run at the terminal laboratory or an independent laboratory, depending on the product and the contract, and results go on a certificate of quality tied to the tank and batch. Retained samples are kept so any test can be repeated if a buyer or inspector questions the result.
