And Performance

In the field of civil and industrial buildings and, particularly, dealing with coverings of wide areas, space truss structures are spreading more and more. Modern tridimensional steel systems are made up to the modular aggregation of standardized structural single or multiple elements, coordinated in space in accordance with rational geometric criteria, mass produced on an industrial scale and designed for a fine and functional architecture. Concerning these structures, the paper presents basic qualitative and performance characteristics, main typologies for the applications and, lastly, some among the most significant structural systems patented by Italian production.

AbstractThe Flash Smelting Furnace (FSF) is one of the most common reactors for the primary smelting of copper concentrates. Its smooth operation depends on the availability and performance of the downstream Waste Heat Boiler (WHB). The WHB is especially sensitive to problems with its flue dust handling, such as the formation of accretions, which can lead to downtime and equipment failures. Due to the limited accessibility and the harsh conditions of the WHB, experimental studies are challenging. Therefore, CFD simulations can be a promising option to increase knowledge and evaluate a range of options. The present study investigates the physical behavior of flue dust in an industrial-scale WHB via a three-dimensional CFD model. Size-dependent particle sedimentation and the risk areas for flue dust accretions are predicted, finding good agreement with industrial experience and data from the literature. To make the evaluation of accretion risk zones possible, a new sticking function for flue dust is developed. The results are validated against dust samples. Finally, operational recommendations for minimizing flue dust accretions are derived.

Demulsification Efficiency

Bio-demulsifier has not been applied in industrial scale due to its production cost. In order to reduce the production cost and improve the efficiency of demulsification, cheap materials such as oilfield sludge, workshop waste oil and edible waste oil were used in experiments as carbon sources to culture PRJ-1 demulsifying bacteria. As a result, cell concentrations of 5.4g/L, 3.7g/L and 4.2g/L were gotten, which were higher than the concentration of 2.6g/L cultivated by using paraffin. PRJ-1 demulsifying bacteria were used to prepare the demulsifying solution with a concentration of 10g/L, which was used in the demulsification experiment on Liaohe crude oil with a water cut of 80%. With 100 ml/L being added into the crude oil, the demulsification efficiency at 12h reached 91%, which was higher than that of 100mg/L chemical demulsifier. Demulsification efficiency of 96% can be achieved by using the combination of 60ml/L demulsifying bacteria and 40mg/L chemical demulsifier, furthermore, the demulsifying speed was higher and dehydrated water was clearer.
