scirj-MATHEMATICAL MODELLING AND OPTIMIZATION OF THE PROCESS OF DERIVING BORIC ACID FROM ULEXITE MIN

Ulexite is a sodium calcium boron hydrate used in producing compounds. Its chemical formula is Na2O2CaO5B2O316H2O, and it superabounds in Turkey. One of the significant boron compounds derived from boron minerals is boric acid. The aim of this study is to produce boric acid in the wake of interaction of ulexite with hydrochloric acid solution, and offering an alternative process to producing boric acid by forming the mathematical model of this processing. Full factorial design method has been used in the study. Some of the parameters used in the process have been made steady, and the others have been accepted as variable factor in formation of mathematical model. Invariant parameters are granule size, reaction time and stirring speed. Hydrochloric acid concentration has been accepted as temperature and solid to liquid ratio variable factors for the formation of mathematical model. Primarily, the mathematical model of the process and three-parameter full factorial design have been...

Since it was formed in 1958 by Mike Costin and the late Keith Duckworth in a small workshop in London, England, Cosworth has become the most successful engine manufacturer in the history of Formula One. In addition it has achieved enormous success in IndyCar, Champ Car, Rally, Sports Car and Touring Car. The company soon outgrew its little workshop in Acton and moved to north London, where the Ford 105E engine was developed. Cosworth’s first race win followed - at Goodwood in 1960, a Formula Junior win for the young Jim Clark. By the mid 1960s the company had moved again, to Northampton, and in 1966 a contract was signed with Ford to develop a new three-litre Formula One engine. The legendary DFV was born. Jim Clark again provided the maiden victory, first time out at the Dutch Grand Prix in 1967. The DFV went on to dominate F1 for 15 years with 155 race wins. In the 1970s the Cosworth DFX ruled the US IndyCar scene with an incredible 151 race wins in a 14-year reign, including 10 driver’s championships and 10 Indianapolis 500 victories. Through the 1980s and ‘90s, Cosworth continued to provide race-winning power with three World Touring Car titles in 1987, ‘93 and ‘94. In Formula One the HB engine won 11 races, while in the US Nigel Mansell’s CART championship in 1993 and Jacques Villeneuve’s in 1995 were both powered by Cosworth XBs. In 1994 the Zetec V8 F1 engine took Michael Schumacher to his first world driver’s title. In rallying the Ford Escort Cosworth and the Duratec-R powered Focus WRC gave Ford yet more success.
