Method for treating bituminous sands |
| abstract |
A method for removing heavy hydrocarbons from bituminous sand comprising the heavy hydrocarbons and a solid substrate is provided. It is characterised by the steps of (1) mixing the bituminous sand with an aqueous cleaning composition comprising a vegetable oil and two emulsifiers and (2) separating the cleaned substrate from a used cleaning composition comprising a two-phase mixture of oily and aqueous phases. Suitable aqueous cleaning compositions are those produced by diluting a concentrate comprising: i) 10 – 60 % by volume of a first emulsifier; (ii) 10 – 60 % by volume of a second emulsifier and (iii) 20 – 70% by volume of vegetable oil 10 In a preferred embodiment the concentrate comprises a polyethylene glycol sorbitan trioleate, a polyoxyethylene sorbitan monopalmitate and corn oil with the two sorbitan molecules having different HLB-values. |
