A packed-bed membrane reactor in a distributor configuration is studied theoretically for the oxidative propane dehydrogenation and compared with fixed-bed reactor. Based on detailed 2D models considering two different heat mass transport scale-up including various reactor-to-particle diameter ratios (D/dP) analyzed respect to performance, transfer hot spot formation. Higher selectivities at lo...
The efficiency of fluidized bed reactors depends on bubble distribution, bubble size and bubble velocity within the reactor. The sizes and size distributions of particles used in the bed may lead to different bubble behaviour. The objective of this work is to study the influence of particle size distribution on bubble behaviour. The results from the experiments will be used for validation of CF...
Expanded bed adsorption chromatography (EBAC) is a single pass operation that has been used as primary capture step in various protein purifications. The most common problem in EBAC is often associated with successful formation of a stable fluidized bed during the absorption stage, which is critically dependent on parameters such as liquid velocity, bed height, particle (adsorbent) size and den...
Abstract Background & Aims: Each year over a hundred million people are undergoing surgery and experience the postoperative pain. Immobility and pain are modifiable risk factors for development of venous thromboembolism and pulmonary morbidity after major abdominal surgery. Documentation from a few studies implies that abdominal binders diminish post-operative pain, seroma formation, psychol...
Case Description- Three domestic short haired cats (2, 5 and 4 years of age) were presented to the Madras Veterinary College Teaching Hospital, with the history of large chronic, full thickness wounds on the right lateral cervical, left caudal forearm and right lateral thoracic region respectively. Etiology of the wounds was trauma in two cases and thermal burns in the third ca...
