Abstract
A method and apparatus for chemical processing. The apparatus comprises an axis about which a plurality of supporting elements are rotated to provide an enhanced gravitational field. Each supporting element is inclined to the axis and each other such that one or more flowable and reactive components can pass from one supporting element to the next in a closely controlled chemical reaction sequence. The one or more supporting elements comprise means, such as holes or notches, for disrupting the flow of the reactive components to either promote mixing or enable free gas or vapour passage.
Claims16
An apparatus for chemical processing comprising an axis about which a plurality of supporting elements are rotated to provide an enhanced gravitational field, each supporting element being inclined to the axis and one another such that one or more flowable and reactive components can pass from one supporting element to the next in a closely controlled chemical reaction sequence, characterised in that the one or more supporting elements comprise means for either controlling the residence time of the reactive components flowing through the apparatus and/or controlling mixing of the reactive components as the reactive components pass from one supporting element to the next.
An apparatus as claimed in any of the preceding claims wherein the supporting elements are nested such that a first plane of a first supporting element is nested one way and a second plane of a second supporting element is sloped the other way under the first plane.
A process for controlling residence time or mixing between one or more flowable and reactive components in an apparatus for chemical processing comprising a plurality of supporting elements, characterised in that a first reactive component is caused to leave one supporting element for another as a fibril or droplet.
A process for reacting at least two chemical reactants on an apparatus for chemical processing comprising an axis about which a plurality of supporting elements are rotated to provide an enhanced gravitational field each supporting element being inclined to the axis and one another such that one or more flowable and reactive components can pass from one supporting element to the next in a closely controlled chemical reaction sequence, characterised in that the supporting elements are arranged or modified or the operating conditions are modified such that one reactive component is able to exit onto a avoiding the requirement to flow the full length of the first supporting element and from the start of the second support element.
A process for reacting at least two chemical reactants on an apparatus for chemical processing comprising an axis about which a plurality of supporting elements are rotated to provide an enhanced gravitational field each supporting element being inclined to the axis and one another such that one or more flowable and reactive components can pass from one supporting element to the next in a closely controlled chemical reaction sequence, characterised in that the first reactant flows across a substantially planar support and wherein a second reactant flows over the first reactant with a flow characteristic close to plug flow.
