Bed Hydrotreatment Processes Apparatus TRIZ Cases
- Convex Catalyst Support Structure for Dead-Space-Free Hydroprocessing
An upwardly convex perforated support cuts reactor dead space, increases catalyst loading, and removes inert support materials.
- Exchange Layer Structure for Gas Resaturation in Liquid Feedstreams
Collector and releaser media increase gas-liquid interfacial area, improving diffusion and reaction rates while reducing coking in process vessels.
- Liquid Feedstream Gas Resaturation with Porous Exchange Layers
Porous collector and releaser media increase gas-liquid contact, resaturating liquid feedstreams and reducing reactant starvation and coking.
- Floating Tray Fluid Distributor for Catalytic Reactors
A floating tray fluid distributor segments into modular units supported by the catalyst bed itself.
- Upflow Reactor Pressing Device for Catalyst Dust Control
A movable pressing device stabilizes pressure on the catalyst bed layer, preventing dust generation and clogging caused by flow fluctuations.
- Hydroprocessing Reactor Cooling via Temporary Heat Exchanger
Temporary heat exchangers cool recycle gas below 400°F, resolving slow cooling bottlenecks during catalyst removal.
- Down-flow Hydroprocessing Reactor Nozzle Mixing
Offset inlet ports merge gas and liquid streams to prevent hot spots and maintain uniform temperature distribution.
- Integrated Hydroprocessing Vessel with Counter-Flow Mass Transfer
An integrated hydroprocessing reaction vessel combines reactor, separator, and stabilization sections to enable efficient mass transfer between low boiling vapor and heavy boiling liquid streams.
- Filter Plate for Fixed-Bed Reactor with Co-Current Gas-Liquid Downflow
A filter plate integrates a granular filtration bed into the distributor system of a fixed-bed reactor to trap clogging particles from the feed stream.
- Inclined Peripheral Conduit Distributor Plate for Trickle-Bed Reactors
Inclined peripheral conduits allow a distributor tray to sit higher in a reactor, increasing catalytic bed height and desulphurization efficiency.
