Fluidized bed agglomeration is an advanced technology to produce spherical coarse-grained material of uniform size ready for sale without any need for post-treatment. This study discusses the possibilities and appropriateness of an intelligent control method such as a fuzzy logic controller in simulating and controlling fluidized bed agglomeration performance. Modeling and simulation was perfor...

Spherical crystallization is a novel particle engineering/design technique developed by Kawashima et al, to overcome the problems associated with direct compression. Basically, it's single step process used for size enlargement of single, two or more, small dose or large dose drugs, in combination with or without diluent. The process of spherical crystallization involves simultaneous crystalliz...

Synthesis of widespread types of nanoparticles including metal oxides by plant extract is considered as alternative chemical synthesis methods. ZnO nanoparticles are synthesized by a biological process using flaxseeds (Linum usitatissimum L.) extract. The biosynthesized ZnO NPs were characterized by XRD and SEM, EDX, DLS spectroscopy. According to the SEM images, the synthesized nanopa...

Natural gas is projected to be the premium fuel of the 21st century because of availability, as well as economical and environmental considerations. Natural gas is coproduced with water from the subsurface forming gas hydrates. Hydrate formation may result in shutdown of onshore and offshore operations. Industry practice has been usage of alcohols--which have undesirable environmental impacts--...

The objective of this work was to study the formation of particles and their morphology and chemical composition in large-scale diesel engines operating with low-grade residual fuel oils. The effect of a Mg-based fuel oil additive on exhaust gas particles was also investigated. Particle characteristics were determined by means of the methods of aerosol technology, chemical analyses, and electro...

Carbon-enriched fractions have been obtained from two coal fly ash (FA) samples. The FA came from two pulverized-coal fired power stations (Lada and Escucha, Spain) and were collected from baghouse filters. Sieving was used to obtain carbon-enriched fractions, which were further subjected to two beneficiation processes: acid demineralization using HCl and HF, and oil agglomeration using soya oi...
