An analysis of the principles of batch and continuous operation
A. KLINKETJBERG N.V. De Efataafsche Petroleum Maatschappij, The Hague. (Royal Dutch/Shell Group)
Summary-An analysis is presented of the meaning of the words " batch " and " continuous," mainly with regard to transfer processes (also called diffusional processes) and with an extension for chemical reactors. In this analysis the various principles of operating such pmcessea are examined. It emerges from this analysis, that there is much diversity in the literature with regard to the use of such words as batch, intermittent, continuous, step wise, co-current, crossflow, multiple contact and so on. Proposals are made for a handling of such terms, that is believed to be a systematic one.
Phually an effort is made to tie the various arguments that enter into a comparison between batch and continuous processing to various aspects recognised in the above analysis.

pn%se la signiiication qu'il donne aux termes " batch " et " continuous," surtout en ce qui conceme les processus de transfer% (appel& au& processus de diffusion) et par extension dans le cas de r&~teura chimiques. Dans cette analyse, il examine les divers principes d'utillsation de tels processus. 11 ressort de cette analyse qu'il y a dans la litt&ature une grande diversite dans l'emploi de mots tels que " batch," " intermittent," " continuous," " step wise," " co-current," " cross-flow," " multiple contact," et ainsi de suite. L'auteur fait des propositions pour l'emploi systknatique de ces termes. Pinalement, il fait un effort pour r&mir les divers arguments qui entrcnt dans la comparaison entre " batch " et " continuous " en tenant compte dea divers aspecta mls en evidence dans l'analyse ci-dessus.
