Lubricity improver

Corrosion inhibitor/lubricity improvement additives are used panicularly in militai y fuel for the dual puiyiose of passivating metal surfaces and improving the lubricating properties of the fuel in equipment such as fuel pumps. The militai y also specifies the use of a fuel system icing inhibitor as an additive to prevent filter blocking by ice crystal formation, because militai y aircraft tend not to use fuel line filter heaters, which are standard equipment on civil aircraft.

Sulfur-free lubricity improvers can be added to restore fuel lubricating properties. Product chemistries and treating rates vary. 

Some chemical additives such as corrosion inhibitors, wax crystal modifiers, detergents, and demulsifiers provide performance which is difficult to duplicate through refining without adversely affecting some other fuel property. Other additives such as metal chelators, fuel sweeteners, biocides, lubricity improvers, foam control agents and combustion enhancers can also be used to solve fuel performance problems. 

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 order to be used as an additive in various types of textile lubricants, surfactants should have high miscibility with base oils as well as the other fundamental surfactant characteristics such as lubricity improving ability and antistatic properties. Table XVI shows the miscibility of C a gAE vari°us lubricant base oils in comparison with that of NPE(IOEO). Good miscibility of SAE can be seen in the Table. Further information, including practical examples, is contained1 in Union Carbide Corp. s booklet on Tergitol 15-S nonionics(20).

Lubricants. Either before milling or afterward a lubricant (wax, polyethyleneglycole, camphor, etc.) is added in amounts of 1-3 wt%. It dissolves in the solvent (acetone, hexan, alcohole) and is distributed homogeneously. It remains in the grade powder and protects it from oxidation after distillation of the solvent. The solvent is recycled to the next batch. Moreover, the lubricant improves the strength of the green compact.

The classic use of methyl esters of vegetable oils has been as intermediates in the production of fatty alcohols from vegetable oils (Peters, 1996 Ahmad et al., 2007) or esterquats and methyl ester sulfonates (Ahmad et al., 2007). Fatty alcohols and the other products are used in surfactants and cleaning supplies. Intermediates were produced from polyisobutylene (PIB) maleic anhydride and rapeseed oil methyl esters which were used to acylate polyethylene polyamines (Hancsok et al., 2006). These additives showed corrosion-inhibiting and lubricity-improving effects. 

Yarns are available in a variety of deniers and merge types that vary in the balance of tensile properties. Special finishes can be applied to increase lubricity, improve fatigue in wet applications, or provide better UV resistance. Ropes using Kevlar or Twaron are particularly useful for static applications or where maximum modulus is required. Technora-based ropes are suited for dynamic applications where resistance to fatigue is important.
