The "Sohar Calciner
" project will produce calcined coke to the local aluminium industry and, upon completion of its first phase, will enable the production of 1.1 million tonnes of aluminium annually and 2.2 million tonnes by the completion of the second phase.
Combining MMEC Mannesmann's expertise and best practice in design and construction of Petroleum Coke Calciner
plants, and Acwa Power's know-how in efficiently utilizing waste heat to generate power and water, the environment friendly project is expected to see remarkable results and contribute towards the country's economic growth.
However, advocate Aparajita Singh who appeared for the Environment Pollution Control Authority (EPCA) requested the court that Calciner
and Aluminium industries may be allowed to import pet coke for use as feedstock.
At the hot end (head) of the kiln, the left side of the calciner
, diesel or petrol is sprayed and burned to generate the heat for the whole calcining and drying process.
"Fuad has demonstrated a successful path in Alba with his results-driven approach and excellence, and I am confident that he will lead calciner
and marine successfully."
The visiting officials were given a tour of Alba's Calciner
& Marine plant and showcased the environmental benefits of the plant.
Al Ali, Dubal's vice-president of supply and a board member of Sinoway Carbon, explained that the new calciner
was built in two equal phases of 280,000 tonnes each: Phase I was completed in May 2013, with Phase II being commissioned.
Unfortunately, in the application shown in Figure 1, because of limitations in the vertical height available between the overflow weir in the side of the calciner
and the lime cooler the solids transfer system as designed could not operate as a stable L-valve because (a) the vertical leg was shorter than the horizontal leg, (b) the aeration point was not positioned above the centre line of the horizontal pipe (c) the discharge end of the horizontal leg was higher than the level of the fluidized bed in the cooler and (d) the valve diameter (200 mm) was so large that the minimum controllable solids flow rate was almost seven times the design production rate.
IMERYS, Atlanta, Georgia, USA said its North American Performance Minerals & Ceramics (NAPMC) will cease production of paper grade products at the Dry Branch, Georgia facility and will be discontinuing operation of its Number 3 Calciner
, a 45,000 ton per year production unit, by the end of December 2005.
For decades, DOE used calcinations to convert liquid radioactive waste to a dry solid and DOE tried to characterize Calciner
The wood and coke were then added to coal at a ratio of 15 percent wood and coke to 85 percent coal, pulverized in a coal mill, and used as fuel to fire burners in the calciner
and rotary kiln at the plant.
The ammoniated brine leaving the absorber at 20o to 25oC is pumped to two carbonating towers in series, in which it first meets lean Carbondioxide gases from the kiln and then rich Carbondioxide from the bicarbonate calciner
. Sodium bicarbonate is formed in the tower, and the slurry leaving the bottom of the second tower consists of sodium bicarbonate crystals and a solution of ammonium bicarbonate and a number of compounds.
