Chemical/Physical Processes TRIZ Cases

A polyolefin reactor uses a cooled recycle stream to remove heat of polymerization through latent heat absorption.

Inverted perforated tube walls replace manual scallop headers with automatic butt welds to reduce production costs.

A horizontal catalytic reactor uses a sliding container to extract the internal bed and heat exchange plates.

Cover plate nozzles create an air cushion that reduces level variations and prevents particle leakage through discrete nozzle groups.

Switching flush medium from inert gas to monomer during polymerization minimizes valuable material loss and lowers inert gas consumption.

A pilot plant process compresses and cools a cycle gas side stream to generate a gas-liquid mixture within a fluidized bed reactor housing.

Segmented lock hoppers separate reaction gases from polymer particles to maintain stable downstream reactor conditions.

A multi-region slurry shell-and-tube reactor uses transverse partition plates with central and auxiliary holes to generate a vortex state for gas-liquid reactants.

Segmented radial nozzles balance asymmetric inlet velocities to prevent catalyst hot spots and extend run time.

An interior sheet with in-plane elongated apertures hinders particulate material from passing through, reducing clogging risk in fluidized bed apparatuses.

Segmented inlet system balances vapor velocities to prevent hot spots and extend catalyst life.

An upstream outlet filter captures fine silicon particles in a fluidized bed reactor to maintain product purity and process continuity.
