gasing pilot plant

intensive gasing pilot plants with loop reactor

general:

this modern pilot plant integrates a new developed loop reactor with a special static mixer and a continuously working filter system for catalysts in suspension.

an extremely high phase transfer of the gas component could be realized without high operation pressure.

application:

fast running processes within the range of gas/liquid reactions

principle of construction:

the design of the plant allows a continuous circulation of the gas phase together with the liquid phase in the whole loop.

therefore unsolved gas is permanently offered to the liquid phase. so the place of reaction is not limited to the reactor but is increased to the whole loop.

this is a big advantage compared with other known loop reactors, where the reaction took place only in a part of the system resp. in a part of the reactor.

this advantage of the intensive gasing plant offers the possibility of high conversion rates realized at low operation pressure and therefore costs saving process conditions.

comparison to stirred autoclave reactors

the picture shows the remarkable improvement of efficiency against stirred autoclaves, comparing the increase of the conversion rate (r) at increased concentrations of catalyst (ccat), realized at constant operation pressure and temperature.

the conversion rate curve of the intensive gasing plant increases exponentially at increased concentrations of catalysts.

in comparison to this the conversion rate realized in a stirred autoclave is very soon limited and does not increase over this limit in spite of an increased concentration of catalyst.

the phase transfer of the gas component is typically more tha power of ten higher at the intensive gasing plants in comparison to stirred autoclaves

resulting advantages

the efficiency of a hydrogenation run on a intensive gasing plant is much higher compared with a stirred autoclave at a reduced input of catalyst.
at a stirred autoclave the concentration of dissolved gas under process conditions is near zero - at the intensive-gasing plant the concentration is close to saturation.

se-lective processes avoiding undesired secondary reactions could be realized easier.
processes close to the theoretical optimum are possible
