Athermal solvent exchange from one organic synthesis step to the next step is highly desirable in bulk pharmaceutical manufacturing due to the thermally labile nature of the active intermediates. Diafiltration (DF) was employed using methanol as the

A mathematical model was derived for describing removal of mixed VOC vapors in biotrickling filters (BTFs). The model accounts for potential process rate limitation by the availability of oxygen as well as for potential kinetic interactions among pol

Multistep organic solvent-based pharmaceutical syntheses of larger organic microsolutes having molecular weights (MW) in the range of 300–1000 generally require athermal separation processes because the active molecules and the intermediates are th

The kinetics of utilization of glucose, phenol, and their mixtures by Pseudomonas putida (ATCC 17514) were studied with a continuously aerated, jacketed batch reactor operating at 28C and pH 7.2. It was found that when glucose is the sole carbon and

The dynamics of a process involving consecutive enzymatic reactions were investigated for a case in which the reactions are carried out in a cyclically operated reactor. Each cycle of the operation protocol involves three phases. During phase I the r

Removal of mono-chlorobenzene (m-CB) vapor from airstreams was studied in a biotrickling filter (BTF) operating under counter-current flow of the air and liquid streams. Experiments were performed under various values of inlet m-CB concentration, air

In this study, a transient biofilter model for binary volatile organic compound (VOC) mixture is developed. In the model, general mixing, oxygen limitation aspects, multi-component adsorption phenomena, Monod- and Andrews-type kinetics with interfere

Mathematical studies for ecosystems involving 2 predators competing for a growing prey population have shown that the 2 competitors can coexist in a state of sustained oscillations for a range of values of the system parameters. For the case of 1 sus
