Channelling in Reactor gen.

[Yerkwantai]

Ув. коллеги,

Подскажите, пожалуйста, как можно перевести channeling in reactor

Chanelling in reactor R-243 A/B due to loss of minimum flow leading to poor treating of comonomer

Chanelling ?? в реакторе R-243 A/B из-за отсутствия минимального потока, что приводит к недостаточной очистке сомономера

Заранее благодарю

"образование каналов"

Из просторов интернетов:

Channelling occurs in fixed bed reactors when the reactants flow through some sections of the reactor bed while bypassing other sections.

Channelling is caused by:

- a poor initial packing of the catalyst bed where the catalyst has been unevenly distributed
- the plugging of sections of the catalyst bed with solid dust or fines
- sudden gas surges through the catalyst bed, or liquid slugs entering the catalyst bed.

Channelling causes poor contact between reactants and the catalyst, resulting in an incomplete reaction and offspec product.

Channelling can be partially compensated for by adjusting the flow rate and temperature parameters, but the only long term solution to channelling is to dump the catalyst and re-pack the catalyst bed with fresh catalyst.

Если речь идет о заряженных частицах и излучениях, то это может быть каналирование.
