Blending Operations

SKU: ROLO00CENDuration: 60 Minutes

Petroleum refinery products are blends of components from various process units plus additives. When the necessary blend components have been combined and any additives have been added, the result is a finished product, such as gasoline, jet fuel, or diesel fuel. In this course, you will explore some common products and the components used to blend them, different methods for blending products, and typical operator responsibilities throughout blending operations.
