    摘要: A method for feeding lime mud into a lime kiln including a rotary kiln shell having an interior between a first end wall and a second end wall, the method including: feeding the lime mud into a flue gas flow in the interior of the rotary kiln shell or in close proximity to the shell to pretreat the lime mud; separating the pretreated lime mud from the flue gas flow; conveying the separated lime mud into the lime kiln, and calcining the separated lime mud in the lime kiln.

    摘要: The invention features methods and systems for calcining wet calcium carbonate lime mud produced in a re-causticizing manufacturing operation, for instance, Kraft pulp mill lime mud (“lime mud”) and converting it to re-burned lime by (a) feeding wet lime mud obtained from a re-causticizing manufacturing process into a flash dryer and then feeding the dried lime mud into a bubbling fluid bed calciner thermally linked by moving media heat transfer (MMHT) utilizing solid particulate media to a circulating fluid bed combustor wherein the MMHT provides heat input for calcination and drying; (b) recycling the media being from said calciner to said combustor wherein said combustor receives mill WWTP sludge, or precipitated lignins, or biomass, or NCGs as fuels to re-heat the solid particulate media; and (c) recovering calcined “soft-burned” lime mud from the fluid bed calciner. Steam and heated boiler feed-water are also generated and exported to the mill's steam distribution and generation system as well as hot process water for use in the mill's boiler house and manufacturing operation. The system for calcining calcium carbonate lime mud produced from a re-causticizing manufacturing operation and converting it to re-burned lime comprises a calciner and a combustor linked by a moving media heat transfer MMHT system or apparatus. The MMHT system or apparatus thermally links separate fluid bed combustion (exothermic) and calcination (endothermic) stages. The system further comprises a flash dryer or spray dryer that utilizes exhausted heat from the calcination stage.

    摘要: A process to make, in part, a refined material for use as crystallization accelerant in cementitious products. Evidence shows that calcium carbonate Fines (Ca+ ions) accelerate the crystallization process of CSH (Calcium-Silicate-Hydrate) phases which lends many advantages in cementitious products. The (PCC) fines materials from the sugar beet processing byproducts consist of these materials with various elements mixed or attached. This process selects for advantageous particles and discards others. This process includes, but is not limited to removing part of the undesirable material by either by screening or biodigestion of the lime to utilize energy contained in said unwanted material to dry in part said particles of PCC to specific moisture content and then screening the material to the remove more unwanted material and size PCC to spec necessary for cementitious materials.
