Abstract
The present invention discloses a homo-polymeric and co-polymeric wax inhibitor (WI) useful for the flow of waxy crude oil and their synthesis thereof. The WI(s) comprises of any one of C14 to C24 fatty alcohol or mixture thereof in 2 mol % to 50 mol %, and an unsaturated organic acid i.e. acrylic acid, and poly alpha olefins i.e. poly alpha hexene, poly alpha octene, poly alpha decene, poly alpha dodecene of composition ranging from about 0.01 wt % to 20 wt % wherein the average molecular weight of poly alpha olefins used ranged from 1000 to 10000. A method of preparing a series of WI(s) with varying compositional ratios of the fatty alcohols, acrylic acid and polyalpha olefins targeting a wide range (C17 to C65 or beyond) of wax present in waxy crude oil is also disclosed.
