چکیده

A distributed dynamic model was built using gPROMS 2.3.7 language for an integrated Process including a cogeneration system, a plate heat exchangers set and a salt recrystallization process. It was analyzed the effect of a simulated spray system model on the integrated process, by comparing the global performance of the system with and without sprays. Due to air drift issues, quasi-random time daily profiles for the allowed operation of the spray system (on-off working time periods) were created. Using three distinctive atmospheric scenarios, several ponds spray distributions schemes were analysed. A sensibility analysis of the salt production was considered by changing the brine flow rate fraction entering in the ponds through taps and by sprays.

Comparison between the SBF response of hydroxyapatite coatings deposited using both a plasma-spray and a novel co-incident micro-blasting technique J.N.Barry, D.P.Dowling

This paper reports on the response of hydroxyapatite (HA) coatings, fabricated using two deposition technologies, to immersion in simulated body fluid (SBF). The deposition methods used were: plasma spray, a commercial standard, and CoBlast, a novel low temperature microblast technique. In the case of the latter, HA coatings are deposited by simultaneous blasting HA and abrasive powders concent...
