Oil and gas toll blending and additive tolling
Updated
Oilfield chemicals and lubricant additives are among the most common toll blends, and among the most demanding on a plant's storage and safety systems.
Talk to a specialist Who owns the materials, who carries the price risk, and the clauses to settle before a formulation leaves your building.
Toll blending for oil and gas
Oil and gas toll blending covers a wide range: production chemicals, fuel additives and lubricant additive packages. What they share is volume, viscous or flammable components, and bulk delivery by tanker or drum.
Ask whether the site receives and loads bulk tankers, what tank farm it has for your inputs, and whether heated storage and heated blending are available, since many additive components are only pumpable warm.
Ashless and automotive dispersant tolling
Ashless dispersant toll manufacturing usually means a reaction step, not only a blend, so it belongs with a site that runs reactions under control and can show the records of doing so. Automotive dispersant tolling into a finished additive package is a blend, but a heavy and heated one.
Ask which of the two a site is offering, and for a reaction step ask how the end point is tested and what goes on the certificate of analysis.
Flammable liquids and process safety
OSHA's flammable liquids standard, 29 CFR 1910.106, governs how flammable liquids are stored and handled at the site. Where a process holds a flammable liquid with a flashpoint below 100 °F in a quantity of 10,000 pounds or more in one location, OSHA's process safety management standard, 29 CFR 1910.119, applies, with a process hazard analysis revalidated at least every five years.
Ask a blender whether your process falls under process safety management at its site, and if so to confirm its program covers it.

Before you commit
Under a toll you buy these inputs, so the price moves on the toll or contract question are at their largest here. Then what to qualify in any blender.
