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.
