The main aim of this experimental work was to develop a separation process using micro- bubbles less than 100 µm in diameter. Micro-agglomerates were produced using 10kg crude oil/tone feed coal treated compared to 250 kg/tone feed coal treated for conventional spherical oil agglomeration. These micro-agglomerates were separated from the unagglomerated minerals by micro-bubble flotation. Colloi...
In this paper, the results of the Spherical Oil Agglomeration of Abstract .45 micrometer superpits low grade co al pa rticles (Bagworth Colliery, U.K.) within a su spension are prese nte d.Demineralized agglomerates were recovered directly by sieving on a 106 micrometer sieve. Verygood reductions in the ash content of the feed coal samples were achieved. In order to reducethe high levels of the...
Present review on the topic explores the different techniques of spherical agglomeration employed in pharmaceutical sciences and their potential applications in developing new particulate systems of drug. Spherical agglomeration is a particle engineering technique which transforms the fine crystals into spherical particles in a single step. These techniques applied in development of new systems...
felodipine is a second generation calcium channel blocker widely used as antihypertensive and antianginal drug which belongs to bcs class ii category. hence, its low water solubility limits the pharmacological effect. the aim of this study was to improve the dissolution rate of felodipine using spherical agglomeration technique with acetone, water and dichloromethane as good solvent, poor solve...
Anti-agglomeration is a promising solution for gas hydrate risks in deepsea hydrocarbon flowlines and oil leak captures. Currently ineffectiveness at high water to oil ratios limits such applications. We present experimental results of a new surfactant in rocking cell tests, which show high efficiency at a full range of water to oil ratios; there is no need for presence of the oil phase. We fin...
We report that a variety of ternary particle/liquid/liquid mixtures heavily aggregate or separate completely if (1) the particles are fully or almost fully wetted by one fluid, and (2) if the wetting fluid volume fraction is comparable to the particle volume fraction. Aggregation and separation do not happen if the particles are partially wetted by both fluids, in which case Pickering emulsions...
Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...
In 1986, Kawashima and their coworkers developed the spherical crystallization technique for size enlargement of the drug in the field of pharmacy. Kawashima defined spherical crystallization as “An agglomeration process that transforms crystals directly into compact spherical forms during the crystallization process.” It also enables co-precipitation of drug and encapsulating polymer in the fo...
