Description
Process for Treating a Mixture of Solid Material and Liquids, Composition Obtainable by the Process, and Use of the Composition
Field of the Invention
The present invention relates to a process for treating a mixture comprising solid material and liquids comprising a first liquid and a second liquid, wherein the first and second liquids have different boiling points. The present invention also relates to a composition comprising a solid material and a second liquid obtainable by the process. Preferably the second liquid comprises an oil. The present invention also relates to the use of a composition comprising a solid material and oil as a fuel.
Background of the Invention
It is well-known in the art that hammer mills can be used to evaporate all liquids from a mixture of solids and liquids. When using such hammer mills, a dry fluidized bed is formed inside the stator due to the rotation of the rotor/hammers and transfer of heat by friction between the hammers and the solid material in the fluidized bed.
The bed will work satisfactorily when it is completely dry and may also work with a small amount of liquids remaining in the bed, i.e. liquids not being evaporated at the set process temperature. By adding some liquid to achieve a higher liquid to solids ratio, it has been experienced that, when treating some mixtures of solids and liquids, the bed will act as a “dough”, i.e. a very highly viscous mixture of solids and liquids, and create unbalance and problems in the process such as, for example, vibration problems and overheating of the hammer mill. In the “dough phase”, the heat transfer will be low since much of the surface area in the dry fluidized bed will no longer be available.
It would be desirable to provide a process in which other types of mixtures of solids and liquids can be treated, e.g. by using a hammer mill. It would also be desirable to provide a process in which the dough phase problems are prevented or, if they would occur, eliminated or at least substantially limited. It would also be desirable to provide a process in which the risks associated with dough phase formation, such as vibrations and/or overheating of the reactor or equipment used, are avoided or mitigated, e.g. when using a hammer mill for carrying out the process.
Summary of the Invention
It is accordingly an object of the present invention to provide a process for treating a mixture of solid material and liquids such as, for example, drill cuttings from the oil industry, and sludge obtained from water treatment or waste water treatment generated from biological and/or chemical processes, wherein the sludge may contain and/or be contaminated by oil, and mixtures thereof. It is another object of the present invention to provide a process for treating such a mixture in which the problems associated with dough phase formation are prevented or, if they would occur, eliminated or at least substantially limited. It is yet another object of the present invention to provide a process for treating such a mixture in which the risks associated with dough phase formation, such as vibrations and/or overheating of the reactor or equipment used, are avoided or mitigated. It is yet another object of the present invention to provide a process for treating a mixture of solid material and at least two liquids in order to separate one of the liquids from the mixture to provide one of the liquids, e.g. in an essentially pure form, and a mixture comprising solid material and the other liquid. Further, it is another object of the present invention to provide a mixture of solid material and liquid obtained / obtainable by the process of the invention. It is yet another object of the present invention is to provide one or more uses of the mixture of solid material and liquid obtained / obtainable by the process.
By using the process of the invention, it is possible to treat a mixture of solid material and liquids having different boiling points. Examples of mixtures that can be treated include drill cuttings from the oil industry which may contain water, oil and organic and/or inorganic solids, and sludge obtained from water treatment or waste water treatment generated from biological and/or chemical processes, wherein the sludge may contain and/or be contaminated by oil, and mixtures thereof. By using the process of the invention, it is possible to separate water from the mixture, thereby providing a mixture of oil and organic and/or inorganic solids which may be used as a fuel, preferably without further processing or purification. Hereby the present invention provides an improved and simplified process for separating one of the liquids from such a mixture, and a simplified process for the production of an oil-based fuel, which lead to environmental and economic benefits and increased productivity. The present invention also provides an oil-based product obtained by the process, and the use of the oil-based product as a fuel. Hereby the present invention provides a valuable product and the use the thereof in valuable applications.
Accordingly, in one aspect, the present invention relates to a process for treating a mixture comprising solid material and liquids comprising a first liquid and a second liquid having different boiling points in a reactor, wherein the reactor comprises a cylindrical reactor chamber, a rotor shaft equipped with radially extending fluidization or mixing units disposed in the reactor chamber, the rotor shaft being connected to a drive unit for rotation of the rotor shaft, one or more inlets for feeding the mixture, solid material and/or one or more liquids comprising the first liquid and/or the second liquid into the reactor chamber, and one or more outlets for discharging of solid material, liquids, gases and vapour from the reactor chamber, wherein the process comprises the steps of:
(i) keeping the mixture in the reactor chamber;
(ii) rotating the rotor shaft to generate heat by friction to the mixture;
(iii) running the process at a temperature which is at or above the boiling point of the first liquid and below the boiling point of the second liquid to evaporate the first liquid;
(iv) discharging the evaporated first liquid out of the reactor chamber;
(v) discharging a mixture comprising the solid material and second liquid out of the reactor chamber.
In another aspect, the present invention relates to a composition comprising a solid material and a second liquid obtainable by the process of the invention. Preferably the second liquid comprises oil.
In yet another aspect, the present invention relates to use of a composition comprising a solid material and oil as a fuel.
These and other objects and aspects of the invention will be described in further detail hereinafter.
