Progress and Development in Melt - Sulphitation Refining at Umfolozi
نویسنده
چکیده
Sublimation can be caused not only by irregular S02 production, due to unsteady supply of sulphur, but also by low combustion temperatures. These can occur when insufficient sulphur is pumped into the burner, as in the case of a clogged nozzle, but also because of cold air·used for the combustions. This is especially the case if the S02 production is below its minimum rating for the plant, which was said to be 250-300 lbs. of sulphur per hour. To overcome this the makers of the plant advised to preheat the compressed air by passing it through a jacket around the first part of the atmospheric cooler. +

Enhancing the effect of soybean oil refinery byproducts on erythromycin production by Saccharopolyspora erythraea
Erythromycin production is clearly enhanced by the addition of vegetable oils. However,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. The non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. In this research, sub-fractions of soybeanoil, including le...
متن کاملRefining grain structure and porosity of an aluminium alloy with intensive melt shearing
Intensive melt shearing was achieved using a twin-screw machine to condition an aluminium alloy prior to solidification. The results show that intensive melt shearing has a significant grain-refining effect. In addition, the intensive melt shearing reduces both the volume fraction and the size of porosity. It can reduce the density index from 10.50% to 2.87% and the average size of porosity in ...
متن کاملSolubility enhancement of glimperide: Development of solid dispersion by solvent melt method, characterization and dosage form development
The aim of the present work was to develop immediate release dosage form of the solid dispersion of glimperide (GLIM) for potential enhancement in the bioavailability. The solid dispersions of GLIM were prepared with PEG6000, PVP K30 and Poloxamer 188, in 1:1, 1:3 and 1:5 %w/w ratio by using solvent wetting and solvent melt method. The in vitro dissolution parameters (%DE10min, %DE30min, %DE60m...

Plasticized sulfur/montmorillonite nanocomposites were prepared by the melt-blending method and the dispersion of montmorillonite (MMT) and the mechanical properties of the nanocomposites were studied. Natural sodium montmorillonite (NaMMT) and organically modified montmorillonite (OMMT) were used as filler. Scanning electron microscope (SEM), X-Ray powder Diffraction (XRD...
