| PROBLEM TO BE SOLVED: To change low quality soil such as soft construction generated soil, mud, dredged soil or the like carried out from a construction work field or the like into excellent sandy improved soil by effectively utilizing industrial waste such as the incinerated substances (quick-lime) of an electric power-plant headrace attachment, coal ash (fly ash) produced from a thermal power plant or the like, desulfurized gypsum or the like. SOLUTION: Sandy improved soil is manufactured by adding and mixing quick lime as a main material and coal ash (fly ash) as an assistant or further a gypsum hemihydrate to soil having low quality such as clay, silt or the like containing water. Soil having low quality has moisture content of 16-60%, and sandy excellent improved soil having at least unconfined compressive strength qn=250 KN/m2 is manufactured by adding and mixing quick lime of 1.0-3.0% and coal ash (fly ash) of 10-30% to soil having low quality. It is more preferable that a gypsum hemihydrate of 0.5-1.5% is added and mixed. When an additional material is mixed by spraying carbon dioxide at adding and mixing it to soil having low quality, the strength of improved soil can be increased and pH can be improved. | ||||||

| An arrangement for burning lime mud into lime in a lime kiln. The lime mud flows counter-currently to flue gases from a feed end to a firing end and the fuel used is flue gas that is produced by gasifying a fuel in the presence of combustion air in a gasifier. The combustion air for gasification is preheated with heat generated in lime mud combustion. The arrangement is provided with a conduit between the lime kiln and the gasifier for leading air from the lime kiln into the gasifier as combustion air. At least a portion of the combustion air for gasification is preheated with heat generated in the lime mud combustion so that air is led into cooling of lime obtained in the combustion and further into the kiln, from or through the firing end of which air is taken into the gasification. | ||||||

| The invention features methods and systems for producing commercial quality carbon dioxide (CO2) of 90% to +99% purity using, wet calcium carbonate lime mud produced in a manufacturing operation, for instance, Kraft pulp mill lime mud (a.k.a., “lime mud”) as a feedstock to a multi-stage lime mud calcination process. This process may be fueled with waste water treatment plant (WWTP), sludge biomass, precipitated lignins, coal, or other low cost solid fuels. High reactivity “soft-burned” lime product (“calcine”) required in the mill's chemical recovery circuit is also produced, and steam and heated boiler feed-water is 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 and CO2 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 with a solid particulate media. The system further comprises a flash dryer or spray dryer that utilizes exhausted heat from the calcination stage. | ||||||

| This invention describes the use of a fluidized bed reactor in the carbonation of a solid, inorganic and alkaline particulate material which contains alkaline metal salts. It also describes a method for treating cement kiln dust (CKD) containing alkaline metal salts. The treatment method comprises two steps: (a) a hydration step; and (b) a carbonation step, wherein the carbonation step is carried out in a fluidized bed reactor. In a preferred aspect of the present invention, the treated CKD is used as an aggregate in sulfur polymer concrete (SPC). Accordingly, the present invention also provides a method for producing SPC, which method comprises heating and mixing treated CKD of the present invention, elemental sulfur and modified sulfur to produce a mixture. The SPC can be used as a barrier to restrict permeation of matter, e.g. in a containment construction for storing matter such as hazardous waste. | ||||||
