Claims8
A method of recovering flowing oil, which comprises the step of:
- solidifying oil flowing into rivers, lakes, marshes or the sea, by adding a recovering material thereto, wherein said recovering material comprises fibrous crystal aggregates which are crystal substances which are formed by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, stirring and gradually cooling the solution thus precipitating said fibrous crystal aggregates.
A method of recovering flowing oil, which comprises the step of:
- solidifying oil flowing into rivers, lakes, marshes or the sea, by adding a recovering material thereto, wherein said recovering material comprises fibrous crystal aggregates which are crystal substances which are formed by making a metal aliphatic carboxylate dissolve completely in sure water to give a solution, adding an aqueous solution of an inorganic salt containing the same metal as in the metal aliphatic carboxylate, stirring, and gradually cooling the solution thus precipitating said fibrous crystal aggregates.
A method of solidifying liquid hydrocarbon, which comprises the step of:
- solidifying liquid hydrocarbon by adding fibrous crystal aggregates thereto, wherein said fibrous crystal aggregates are crystal substances which are formed by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, stirring, and gradually cooling the solution thus precipitating said fibrous crystal aggregates.
A method of solidifying liquid hydrocarbon, which comprises the step of:
