Abstract
Embodiments of the disclosure pertain to a chemical reactor comprising a mixing zone comprising first static mixer and a second static mixer both arranged in shell of the reactor, wherein the second static mixer is positioned further from said first inlet than said first static mixer, wherein the second static mixer is adapted for more intimate mixing of fluids in the reaction mixture than the first static mixer.
Claims23
A chemical reactor comprising a shell for holding a reaction mixture, a first section and a second section in said shell, a first inlet for a first fluid stream and a second inlet for a second fluid stream, wherein both inlets are arranged in said first section, the reactor further comprising an outlet for reactor effluent withdrawn from said second section, and a mixing zone in said first section of the reactor adapted for mixing said first and second fluid stream,
- wherein the mixing zone comprises a first static mixer and a second static mixer both arranged in said shell, wherein the second static mixer is positioned further from said first inlet than said first static mixer, wherein the second static mixer provides a plurality of adjacent fluid passages that have a characteristic dimension (d2) that is at least 4 times smaller than a characteristic dimension (d1) of channels comprised in the first static mixer, wherein d1 and d2 are respectively defined by a maximum dimension of a solid sphere that can pass without deformation.
A chemical reactor comprising a shell for holding a reaction mixture, a first section and a second section in said shell, a first inlet for a first fluid stream and a second inlet for a second fluid stream, wherein both inlets are arranged in said first section, the reactor further comprising an outlet for reactor effluent withdrawn from said second section, and a mixing zone in said first section of the reactor adapted for mixing said first and second fluid stream,
- wherein the mixing zone comprises a first static mixer and a second static mixer both arranged in said shell, wherein the second static mixer is positioned further from said first inlet than said first static mixer,
- wherein said first static mixer comprises a disc element and a donut element,
- wherein the second static mixer comprises mixing elements which each comprise an edge that is adapted for dividing a flow of the reaction medium in the reactor into two sub-flows, the second static mixer further comprising channels for said sub-flows, wherein said channels are tapered and converging in the flow direction.
A chemical reactor comprising a shell for holding a reaction mixture, a first section and a second section in said shell, a first inlet for a first fluid stream and a second inlet for a second fluid stream, wherein both inlets are arranged in said first section, the reactor further comprising an outlet for reactor effluent withdrawn from said second section, and a mixing zone in said first section of the reactor adapted for mixing said first and second fluid stream,
- wherein the mixing zone comprises a first static mixer and a second static mixer both arranged in said shell, wherein the second static mixer is positioned further from said first inlet than said first static mixer,
- wherein the first static mixer and the second static mixer each comprises mixing elements and channels for reaction mixture to flow through the shell, wherein the channels comprised in the second static mixer are narrower than the channels comprised in the first static mixer,
- wherein the first section extends over up to 10% of the length of the reactor and comprises the first and second static mixer as well as the first and second inlet;
- and wherein the second static mixer is arranged downstream of the first static mixer, relative to the flow of the first and second fluid stream.
