Technology developed by the N.N. Zoubov Engineers research center has the following features:<\/p>\n
v\tReduction of emission of CO2 by 12% ;
\nv\tEnergy saving by 15% ;
\nv\tIncreased cement grade ;
\nv\tEfficiency increase by 50% without installing new machinery.
\nThe presented technology is commissioned in two producing plant in 2007.<\/p>\n
Technology Outline:<\/p>\n
There are two stages:<\/p>\n
Stage I:<\/p>\n
Identification of the site of the deposit (volcanic, magmatic rock) from which the added materials is obtained and added into the clinker. For cost efficiency, the deposit site preferably is to be within the range of 150 km from the cement plant. Then flour composition is formulated based on the constituents of the input.
\nHere is an example of calculus performed for the cement plant.<\/p>\n
The furnace in the initial stage has the following parameters:<\/p>\n
•\tFlour load: 210 ton per hour;
\n•\tGas consumption: 13500 cubic meter per hour.<\/p>\n
Clinker output is calculated as 210 x 0.6 = 126 ton per h for 0.6 coefficient.
\nFor the obtainment of the Portland cement in concern, the following changes have been made:<\/p>\n
•\tFlour load: 227 ton per hour;
\n•\tGas consumption: 12352 cubic meter per hour.<\/p>\n
Reaction capacity of the clinker has increased by 0.3% (or the coefficient is 0.03) after addition of the rock into the flour. The clinker calculation is then performed by 0.6 + 0.03 = 0.63 coefficient. Thanks to the added material’s inner property, the part of the dust (averagely 4 ton) is entered into the clinker thus increasing its content. <\/p>\n
So, by applying this technology, we get the following amount of clinker: 227t x 0.63 = 143t + 4t of dust = 147t. The difference is 147 – 126 = 21t or 18% increase of output rate.<\/p>\n
The consumed gas (as per the ton) is: <\/p>\n
•\tConventional technology: 13500 m3 : 126 T = 107,14 m3 per ton;
\n•\tNew technology: 12352 m\u00b3 : 147T = 84,027 m\u00b3 per ton ;
\n•\tDifference: 107,14 m\u00b3 – 84,027 m\u00b3 = 23,113 m3 or 20% of gas saving.<\/p>\n
Stage II:<\/p>\n
To the obtained clinker a corresponding additive is selected and calculated (dunite, peridotite, diatomite, serpentinite, etc.) which later loaded into cement mill. The output rate of the ball mill is increased up to 15% by appropriate selection of the assortment of balls.<\/p>\n
The obtained Portland cement strictly corresponds to specifications.<\/p>\n
