in order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. the purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity. second order chemical reaction for two different cases (fast and slow) were considered. the system partial differential equations obtained was...

abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...

Filem selulosa terjana semula (FSTS) merupakan produk yang dijana daripada terlarut secara interaksi fizikal mahupun kimia. Sifat fizikal, mekanikal dan kimia FSTS bergantung kepada jenis pelarut digunakan terhadap selulosa, agen penggumpalan, teknik penuangan serta kaedah pengeringan. Pembentukan sangat keterlarutan proses penjanaan semulanya. Oleh itu, mekanisma pembubaran di dalam terbitan t...

This paper includes the significant on-site experience of the authors related to problems faced in amine systems with fresh amine and their possible solutions in phases#2&3 of South Pars gas                complex. The amine system was designed as a closed circuit system with the primary objective of removing H2S, CO2, and other acidic components from gaseous hydrocarbon streams. Amine plant op...
