Abstract
Provided is an advanced liquid centrifuge using differentially rotating cylinders moveable rings at the ends thereof, as well as methods for the separation of fluids, preferably liquids.
Claims16
A method of separating a composition into two or more component fractions or parts, comprising:
- providing the composition to an apparatus which comprises an annulus for the containment of a composition which annulus exists between an a rotatable inner cylinder, a rotatable outer cylinder, and one or more rotatable rings which extend between the inner cylinder and the outer cylinder, which aforesaid elements are all independently rotatable, with respect each other, such that a liquid can be retained within the annulus when one or more of these elements are in motion,
- operating the apparatus so that the rotational speed of at least one of the inner cylinder, outer cylinder and one or more rotational rings move at a speed which is different from the speed of one or more of the other inner cylinder, outer cylinder and one or more rotational rings present within the device such that over an interval of time, the distribution of components present within a composition between the inner cylinder and the outer cylinder changes due to the motion of one or more of the elements of the apparatus (separation).
A method of mixing two or more separate compositions to form a mixture, comprising:
- providing the separate compositions to an apparatus which comprises an annulus for the containment of a composition which annulus exists between an inner cylinder, an outer cylinder, and one or more rotatable rings which extend between the inner cylinder and the outer cylinder, which aforesaid elements are all independently rotatable, with respect each other, and in which a liquid tight seal is present between adjacent elements such that a liquid can be retained within the annulus when one or more of these elements are in motion;
- operating the apparatus so that the rotational speed of at least one of the inner cylinder, outer cylinder and one or more rotational rings move at a speed, which is different from the speed of one or more of the other inner cylinder, outer cylinder and one or more rotational rings present within the device such that over an interval of time, the distribution of components (mixture) present within a composition between the inner cylinder and the outer cylinder changes due to the motion of one or more of the elements of the apparatus.
A method of performing a chemical reaction and/or enhancing, and/or controlling a chemical reaction within a composition, comprising:
- providing one or more compositions to an apparatus which comprises an annulus for the containment of a composition which annulus exists between an inner cylinder, and outer cylinder, and one or more rotatable rings which extend between the inner cylinder and the outer cylinder, which aforesaid elements are all independently rotatable, with respect each other, and in which a liquid tight seal is present between adjacent elements such that a liquid can be retained within the annulus when one or more of these elements are in motion;
- operating the apparatus so that the rotational speed of at least one of the inner cylinder, outer cylinder and one or more rotational rings move at a rotational velocity which is different from the speed of one or more of the other inner cylinder, outer cylinder and one or more rotational rings present within the device such that during the operation of the apparatus, one or more chemical reactions occur within the annulus to form one or more reaction products.
