“…the option 2) will reduce the cost of wiring and piping significantly. One can comprehend the importance of piping design from piping costs, which can run as high as 80% of the cost of purchased equipment and hence, constitute a substantial part of the capital cost [7]. Besides, option 2 will make operators' movement between control room and each plant site more convenient.…”

“…The present work is aimed to provide an easy way to check risk associated with different locations within the battery limit of a plant. Grid based risk mapping of an existing ammonia-urea plant is done following the methodology developed by Jung (2010) [7]. Three main units of ammonia plant, namely, the primary reformer, secondary reformer and the ammonia converter and two units of urea plant, namely, the urea converter and high pressure carbon dioxide stripper have been considered for accidental release.…”

Abstract:In this study safer facility siting of an ammonia-urea complex is demonstrated by risk mapping. This risk map is useful for identifying safer zones within the plant at the design stage as well as before setting temporary shelters, i.e. shelters for contractors and maintenance workers etc. in an existing plant. To prepare the risk map a number of critical process units of an ammonia-urea complex are selected as the sources of toxic release and blast overpressure. Locations of control room and three operators' shelters are considered with respect to five critical units. Consequences of toxic release and blast overpressure are modeled for various worst case scenarios developed in the critical units. Both structural damage and human mortality/injury are converted into risk scores. Risk mapping of the battery limit area are done and locations with minimum risk scores within plant area are identified for the probable siting of the control room and operators' shelters. The findings are compared with the layout of an existing ammonia-urea complex. It is also shown that a simple risk mapping of the plant area is helpful in avoiding facility siting in high risk zone at the same time finding safer locations for different facilities.

By chemical cross-linking the amidoxime group onto dual-surfaces of natural ore materials,n amely halloysite nanotubes (HNTs), an efficient adsorbent, AO-HNTs,i s developed. AO-HNTs show high uranium adsorption capacity of 456.24 mg g À1 in 32 ppm uranium-spiked simulated seawater.I nn atural seawater,A O-HNTs reach the high uranium extraction capacity of 9.01 mg g À1 after 30 days field test. The dual-surface amidoximated hollown anotubular AO-HNTs exhibit more coordination active sites for uranium adsorption, which is attributed to the high and fast uranium adsorption capacity.Because of the stable natural ore structure,AO-HNTs also show long service life.B enefiting from the low cost of HNTs,the cost for uranium extraction from seawater is close to the uranium price in the spot uranium market, suggesting that AO-HNTs could be used for economical extraction of uranium from the oceans.
