Level Measurement Solutions for Blending Operations

After petroleum has been refined and processed, the finished feedstocks must be blended together in order to insert additives and produce the final product. Mixing finished gasoline requires level monitoring of blending stocks, in-line blending, additive storage, dilution systems and injection systems. Blend stocks are straight-run gasoline, alkylate, reformate, benzene, toluene and xylene. Additives include octane boosters, metal deactivators, anti-oxidant and knock agents, gum and rust inhibitors, and detergents.

Blending operations are the final step in creating the products of petroleum refining. To ensure that the care taken with the rest of the refining process does not go to waste, blending additives with stocks should involve the same level of care and attention to detail. blending operations

Magnetrol® has produced an applications brochure for the petroleum refining industry detailing level measurement challenges and considerations for each step of the refining process. This blog post is part of an occasional series exploring each application in detail.

Level Measurement Challenges and Considerations

Level is normally measured only for inventory control and, in some cases, custody transfer. The precision of level indication that is required varies. If level is used only for internal inventory control, a less accurate measurement can be used. If level is used for custody transfer, highly accurate measurements are required. In either case, level instruments must be able to perform efficiently and safely with as little downtime as possible.
