(B) MATHEMATICAL MODEL OF LINE DISSOLUTION. As CaCO3 dissolves from the line contactor media, particle size, bed depth, bed porosity, flow velocity and pressure drop change with time. It is important to make design choices for these variables since they affect the dissolution rate and recharge.
Mechanisms for Calcination and Sulfation of Line . - IEAGHG
This paper aims to clarify the mechanisms governing the calcination and sulfation of line during oxy-fuel combustion. Apart from pure line, the mixtures of line with a low-rank brown coal at three different mass ratios were combusted in an lab-scale drop-tube furnace (DTF) to systematically examine the.
WRI-05-R013 OPTIMIZATION OF TRONA/LINE . - OSTI
The lower reductions were attributed to dead-burning of the sorbent in the high temperature flame zone. In cases where line was both injected into the furnace and added to the coal, the total SO2 reductions for a given Ca:S molar ratio were similar to the reductions for furnace injection only. The injection of trona into.

Effect of line particle size and calcium to non-phytate .
Effect of line particle size and calcium to non-phytate phosphorus ratio on true ileal calcium digestibility of line for broiler chickens . Increasing Ca:non-phytate P ratios reduced the true Ca digestibility of line. The true Ca digestibility coefficients of line with Ca:non-phytate P ratios of 1.5, 2.0 and 2.5.
fbc desulfurization process using coal with low sulfur . - CiteSeerX
molar ratio, desulfurization efficiency decreased in relation to the increased Ca/S. Thus, it must be highlighted that the efficiency of desulfurization is strongly dependent on the initial SO2 concentration in the bed (Fig. 1). The addition of line at Ca/S = 1 promoted a reduction of the SO2 emission from 900 ppm to ~450.
Effects of Particle Size Distribution on the Burn Ability of Line
The role of the process is to reduce the particle size of the line, get benefit in low heat of calcinations. In the materials processing industry, size reduction or comminution is usually carried out in order to increase the surface area because, in most reactions involving solid particles, the rate of reactions is directly.
