Diesel fuel lubricity

Additives identified as lubricity improvers are sometimes used to improve the wear-inhibiting properties of low-viscosity 1 diesel fuel and higher viscosity hydrotreated low-sulfur 2 diesel fuel. Lubricity improvers are available as single products or may be contained within a diesel fuel performance additive package. In addition to distillate fuel lubricity, gasoline lubricity is being investigated. 

In recent years, the concern over fuel lubricity has led to the use of a high concentration of corrosion inhibitors to improve diesel fuel lubricity performance. The film formed on the metal surface by fatty acid type corrosion inhibitors improves fuel lubricity. However, the result of this overtreatment may lead to sticking of injection pump parts.

The waste water is composed of coolants, cutting oils, diesel fuel, lubrication oils, hydraulic oils, wash tank solutions, de-greasers, and phosphate rinse from the painting operation. A typical analysis of the waste water shows pH = 8... 

The copper strip test methods are used to determine the corrosiveness to copper of gasoline, diesel fuel, lubricating oil, or other hydrocarbons. Most sulfur compounds in petroleum are removed during refining. However, some residual sulfur compounds can have a corroding action on various metals. This effect is dependent on the types of sulfur compounds present. The copper strip corrosion test measures the relative degree of corrosivity of a petroleum product.

The versatility of hydrocracking was demonstrated in the 1960 s as the demands for a variety of products increased. In addition to gasoline and jet fuel, the product range included diesel fuel, lubricating oils, low sulfur fuel oils, LPG, and chemicals. 

When an ideal liquid solution containing two volatile components is in equilibrium with its vapor, the more volatile component will he relatively richer in the vapor. This fact forms the basis of distillation, a technique used to separate (or partially separate) mixtures containing volatile components. Distillation is the procedure by which a moonshiner obtains whiskey using a still and by which petrochemical plants achieve the separation of crude petroleum into gasoline, diesel fuel, lubricating oil, and so forth ( FIGURE 13.22). Distillation is also used routinely on a small scale in the laboratory.
