Spray dry granulation of clay minerals was studied to obtain clay mineral base support material for metallocene supported olefin polymerization catalysts. The morphology of the granules was strongly influenced by the nature of the clay mineral itself. Because of swelling characteristics of montmorillonite, its water dispersion was highly viscous even in the low slurry concentration (< 4 wt %). ...
Spray dryers are widely used in the chemical, pharmaceutical and food industries to turn liquid products into free flowing powder. To increase the energy efficiency and improve the product quality, the dryer in question combines drying in four stages, instead of single stage drying. In this paper, we present our latest developments within advanced process control for the four-stage spray dryer....
Two control laws, to control the liquid pressure of an agricultural spray boom are presented and compared. Characteristic for the process is a dead zone and a time varying delay. The first control law is rather intuitive and is based on direct dead zone compensation and a pole placement idea. The other control law originates from sliding mode control where the continuous part of the control con...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
