Abstract
Horizontal adiabatic reactor (1) for heterogeneous catalytic reactions, comprising an outer cylindrical shell (2), an inlet (6) for reagent gases and an outlet (7) for gaseous products, a basket (10, 13) containing a catalytic bed (5a, 5b) positioned horizontally inside said reactor, wherein said reactor is configured in such a way that the gases cross said catalytic bed in a radial or axial-radial manner, said shell (2) has a cover (4) which can be opened and which defines an opening (20), and said basket (10, 13) is extractable horizontally from said opening.
Claims6
A horizontal adiabatic reactor for heterogeneous catalytic reactions, comprising:
- a cylindrical outer shell,
- an inlet for a flow of reagent gases and an outlet for a flow of gaseous products;
- at least one basket containing at least one catalytic bed, said catalytic bed being positioned horizontally inside said reactor;
- wherein:
- said reactor is configured in such a way that said gas flow crosses said at least one catalytic bed in a radial or axial-radial manner, wherein said at least one catalytic bed has an annular configuration and radial symmetry;
- and
- said shell has a cover which can be opened and defines an opening and said basket can be extracted horizontally from said opening;
- the reactor comprising a first catalytic bed in the centre of which a coaxial heat exchanger is housed, and a second catalytic bed in the centre of which a coaxial gas discharge tube is housed.
A method for replacing catalyst in an adiabatic horizontal catalytic reactor, the adiabatic horizontal catalytic reactor comprising:
- a cylindrical outer shell;
- an inlet for a flow of reagent gases and an outlet for a flow of gaseous products;
- at least one basket containing at least one catalytic bed, said catalytic bed being positioned horizontally inside said reactor;
- wherein:
- said reactor is configured in such a way that said gas flow crosses said at least one catalytic bed in a radial or axial-radial manner, wherein said at least one catalytic bed has an annular configuration and radial symmetry;
- and
- said shell has a cover which can be opened and defines an opening and said basket can be extracted horizontally from said opening;
- wherein the method comprises the following operations:
- horizontally extracting said basket from said shell;
- vertically positioning said basket;
- removing the used catalyst from said basket in a vertical position;
- inserting fresh catalyst inside said basket in a vertical position;
- and
- reintroducing said basket in a horizontal position and inserting it inside the shell.
