Patent Abstract

The invention relates to an additive and its use for improving the flow properties of paraffinic crude oil, a process for preparing a crude oil composition with a pour point reduced compared to the crude oil, and a crude oil composition comprising the additive. The object of the present invention is therefore to provide a way to favorably influence the pour point of crude oil and thus improve the flow properties of crude oil. In one aspect, the invention provides an additive for improving the flow properties of paraffinic crude oil, wherein the additive comprises 20-40 wt.-% of at least one copolymer of at least two comonomers, and wherein the comonomers are selected from groups (a) and (b) of comonomers, and wherein group (a) of comonomers consists of acrylic acid and methacrylic acid, and group (b) of comonomers consists of styrene and a styrene derivative.
