Embodiment

[0040] The following examples illustrate but do not limit this embodiment.

[0041] The following components are used in the examples:

[0042] A 425. Conductivity enhancing additive available from Innospec Fuel Specialties, LLC.

[0043] B TOLAD TM 3514. Conductivity enhancer available from Baker Petrolite.

[0044] C TOLAD TM 3512. Conductivity enhancer available from Baker Petrolite.

[0045] D. 4130SM. A modification of 4130S, a multipurpose fuel additive concentrate available from Afton Chemical. It includes succinimide cleaners, ester-based lubricant additives, corrosion inhibitors, demulsifiers, aromatic solvents and alcohol co-solvents. 4130SM and the unimproved type ( 4130S) has a lower level of detergent.

[0046] In each example, the 4130SM Additive Concentrate was added at 290 ppm to ultra-low diesel fuel available from ExxonMobil. The additive concentrate contains the basic nitrogen component in the form of a succinimide cleaner. Then, anti...

Abstract

The disclosure provides conductivity improving concentrates and methods for improving conductivity and reducing risks associated with static discharge in middle distillate fuel compositions, particularly ultra-low sulfur diesel fuels. The conductivity improvement is provided in the presence of a basic nitrogen component and is sustained for an extended period, thus permitting the antistatic agent to be pre-blended with in an additive concentrate or to the fuel well in advance of the time when the improved conductivity might actually be needed, such as when the fuel is dispensed into a bulk container.

Description

technical field [0001] The present invention relates to compositions and methods for increasing the conductivity of middle distillate fuel compositions, especially diesel fuels, most especially low sulfur and ultra low sulfur diesel fuels. Background technique [0002] Certain middle distillate fuel compositions, especially diesel fuel, can generate static electricity, especially during rapid movement, such as filling fuel into tanks or other bulk containers or containers. Although diesel fuel is not extremely volatile, the tanks used to transport diesel fuel are also used to transport gasoline, kerosene and other more volatile and flammable liquids. Even after the more volatile fuel is drained from the tank, vapors may still be present and there is a risk of fire or explosion from sparks generated by the discharge of the static charge of the fuel composition. [0003] These hazards have become more acute in recent years with the increased popularity and use of low-sulfur f...
