Eductors having hydrophobic surfaces and methods of reducing deposition of a friction reducer on a surface

Abstract

The present invention provides eductors comprising: a component having a metal surface: and a hydrophobic surface layer applied thereto, directly or through an intermediate layer. The surface layer comprises a self-assembled monolayer prepared from a fluorinated material having the structure: wherein A is an oxygen radical or a chemical bond; n is 1 to 20; Y is H, F, CnH2n+1 or CnF2n+1; X is H or F; b is at least 1, m is 0 to 50, p is 1 to 20, and Z is an acid group or an acid derivative. Also provided is a method of reducing deposition of a friction reducer on a metal surface of a component of an eductor, comprising: contacting the surface with a fluorinated material in a diluent, wherein the fluorinated material has the structure above; forming a film on the metal surface; and introducing the friction reducer into the apparatus.
