ABSTRACT:
A chemical composition of matter comprising a wax plasticizing agent (plasticizer) tributoxyethyl phosphate, a mixture of selected long chain fatty acids (preferably C10to C22), and a mixture of selected low-surface tension surfactants, which when added in solution to crude oil or refined products has been shown to lower both the B.S. & W. (rag layer) and the coefficient of friction of crude oils and refined products. This chemical composition of matter is particularly useful as a wax liquefaction, dispersant, and solubilization agent for asphaltene and paraffins in crude oil and refined products. The reduction in the co-efficient of friction resulting from the addition of this product to crude oil will allow crude oil to pump through pipelines with a minimum amount of resistance due to friction (drag).
