Interaction between a Side Chain Crystalline Block Copolymer and Wax
Journal Title: Petroleum & Petrochemical Engineering Journal - Year 2018, Vol 2, Issue 7
Abstract
Petroleum has the property that as the ambient temperature decreases, wax contained within is precipitated out. This phenomenon causes a reduction in the effective diameter of pipelines used for the transport of crude oil, and can result in the blockage of pipelines. A further issue is that, sludge accumulates at the bottom of petroleum storage tanks. Therefore, the tanks regularly have to be manually emptied and cleaned in order to remove the sludge. This work is extremely dangerous, as fires and fatal accidents have frequently occurred. To solve these issues, the use of various additives has been proposed. In recent years, we have synthesized a block copolymer of acrylate monomers with long alkyl side chain and solvophilic monomers. The SCCBC, in particular, exerts a very remarkable dispersant effect for a concentrated PE particle dispersion. In this study, we have investigated the influence of the addition of the SCCBC on the crystallization of model wax/oil mixtures, and the temperature dependence on its rheological properties. Examination of the temperature dependence of viscosity or viscoelasticity revealed that the addition of SCCBC prevents the wax/oil mixed system from losing fluidity, even at the low temperatures at which wax would normally solidify. The non-solidification and fluidization effects of the model wax/oil mixed system, described herein, will be helpful in reducing blockages in pipelines for crude oil and in reducing the accumulation of sludge at the bottom of oil storage tanks.
