A method of transporting oil

A method of transporting oil comprising the steps of

• (A) providing a solid particles-stabilized emulsion comprising water as continuous phase, oil as a dispersed phase and at least one magnetic solid particle which comprises layered double hydroxide,
• (B) pumping said solid particles-stabilized emulsion through a conduit or pipeline
• and
• (C) breaking the solid particles-stabilized emulsion by applying a magnetic field to obtain oil.

A method of transporting oil comprising the steps of

• (A) providing a solid particles-stabilized emulsion containing water as continuous phase, oil in the form of droplets having an average droplet size Dv50 in the range of 1 to 100 μm as a dispersed phase and at least one magnetic solid particle which comprises layered double hydroxide of general formula (I)
• [MII(1-x)MIIIx(OH)2]x+[An−]x/n.yH2O (I),
• wherein
• MII is a divalent metal ion selected from the group consisting of Ca, Mg, Fe, Ni, Zn, Co, Cu and Mn or 2Li,
• MIII is a trivalent metal ion selected from the group consisting of Al, V, Co, Sc, Ga, Y, Fe, Cr and Mn,
• An− is an n-valent anion selected from the group consisting of OH−, CH3COO−, PO43−, Cl−, Br−, NO3−, CO32−, SO42− and SeO42−,
• x is the mole fraction having a value ranging from 0.1 to 0.5 and
• y is from 0 to 5.0,
• (B) pumping said solid particles-stabilized emulsion through a conduit or pipeline
• and
• (C) breaking the solid particles-stabilized emulsion by application of a magnetic field to obtain oil.
