In the present study, simulation of a divided wall column (DWC) was carried out to study the product quality and energy efficiency as a function of reflux rate, liquid spilt and vapour split for the separation of C4-C6 normal paraffin ternary mixture. Rigorous simulation of the DWC was carried out using Multifrac model of Aspen Plus software. Box–Behnken design (BBD) was used for the optimizati...
Throughout the world, there has been an increasing incidence of fungal infections, and because of drug resistance and toxicity associated with long-term treatment with antifungal drugs search for new drugs to treat fungal infections is ongoing. The aim of this study was to evaluate the physicochemical properties and stability of creams containing different concentrations of Zataria mu...
Magnetic fluids are stable colloidal systems of fine single-domain magnetic particles (for example Fe3O4, γ-Fe2O3, Co, MnFe2O4, etc.) that are suspended in liquid carrier such as water, mineral oil, damping oil, paraffin, kerosene and so on. The properties of magnetic fluids are well controlled by external magnetic field that gives broad possibilities for technical and biomedical applications. ...
Background and Aim: Direct immunofluorescence (DIF) is represented as a gold standard method in diagnosis of autoimmune blistering dermatoses. Normal saline, liquid nitrogen and michel’ solution are a widely accepted media for preserving biopsy samples of skin or mucosa before DIF examination. Occasionally clinicians put the biopsy specimen taken for DIF in formalin 10%, occasionally clinicians...
The ternary phase diagram for N-[3-lauryloxy-2-hydroxypropyl]-L-arginine L-glutamate (C12HEA-Glu), a new amino acid-type surfactant, /oleic acid (OA)/water system was established. The liquid crystal and gel complex formations between C12HEA-Glu and OA were applied to a preparation of water-in-oil (W/O) emulsions. Stable W/O emulsions containing liquid paraffin (LP) as the oil and a mixture of C...
The Influence of Additives on the Rheological and Sedimentary Properties of Magnetorheological Fluid
In this research, the influence of additives on rheological and sedimentary properties magnetorheological fluid (MRF) was tested analyzed. The were stearic acid, sodium dodecyl sulfate (SDS), their mixture, respectively. MRF composed carbonyl iron particle, silicone oil, liquid paraffin, graphite bentonite, SDS. results indicated that mainly influenced by mass fraction particle. When fractions ...
Abstract The corrosion performance of phase change materials on stainless steel was studied using single fatty acid, acid/paraffin mixed and acid/paraffin/graphite composite as media. results show that the paraffin graphite to is very small; among them, stearic acid series are least corrosive can be used ideal energy storage medium for heat exchange devices.
