Abstract
ENGLISH ABSTRACT: A study was made of the design of membrane contacting systems comprising non-porous polymeric membranes and the performance of such systems evaluated in various operations, namely; Oxygenation/deoxygenation of water, ethylene/ethane separation, and separation of liquid olefin/paraffin mixtures in the range of C4 to C10. A novel mass-transfer model for gas separation by such systems is proposed. Physicochemical principles of separation processed by means of such systems are discussed.
AFRIKAANSE OPSOMMING: In hierdie studie is membraan kontak sisteme bestaande uit nie-poreuse polimeriese membrane ontwerp en geëvalueer, naamlik; oksigenering en deoksigenering van water, etileen/etaan skeiding en die skeiding van vloeibare olefien/paraffienkoolwaterstofmengsels in die homoloë reeks tot by C10. Die fisies-chemiese beginsels van die skeidingsprosesse deur middel van hierdie sisteme is bespreek. 'n Massaoordragmodel vir gasskeiding deur hierdie sisteme is ook voorgestel.
