BACKGROUND OF THE INVENTION 1. Field of the Invention
Embodiments of this invention relate to systems and methods for making cement and to cement compositions derived therefrom.
More particularly, embodiments of the present invention relate to systems and methods for making cement and to cement compositions derived therefrom, where the system includes a cement raw material supply subsystem, a burnable fuel supply subsystem, a cement kiln subsystem, and a cement storage and distribution subsystem. Embodiments of the systems of this invention integrate a healthcare materials (used or unused) supply and conditioning subsystem into a traditional cement subsystem so that healthcare materials (used or unused) can be directly used as a fuel and/or a raw material in the cement production.
2. Description of the Related Art
Cement clinker is produced by feeding a mix of raw materials, such as limestone and silica-containing materials, into a high temperature rotating kiln. Generally, crushed raw materials are stored on site at a cement plant in raw material storage facilities, such as a raw material silo or other suitable storage means. In addition to limestone, raw materials may include clay and sand, as well as other sources of calcium, silicon, aluminum, iron, and other elements. Raw material sources may be transported from a nearby quarry or other sources.
The various raw material components are fed by a raw material feeder into a grinding and mixing facility, such as a raw mill. Raw material components may also be fed directly to a rotating kiln. The final composition of the raw mix depends on the composition and proportion of the individual raw material components. The proportion of the raw material components in the raw mix depends on the rate at which each component is fed into the raw mill or into the kiln.
The raw mix is heated in the rotating kiln, where it becomes partially molten and forms clinker minerals, or cement clinker. The cement clinker then exits the kiln and is rapidly cooled. The cooler may include a grate that is cooled by forced air, or other suitable heat exchanging means.
Clinker kiln dust may be emitted from the kiln and from the cooler, along with exhaust emissions. For example, clinker kiln dust may become suspended in the forced air used to cool the clinker exiting the kiln. The forced air may be filtered and reclaimed clinker kiln dust from the filter may be fed back into the kiln system as a raw material input.
Fuels such as coal and petroleum coke are used to feed the kiln flame to heat the raw mix in the kiln. Other fuels may include whole tires, tire chips, or other alternative fuels such as liquid wastes and plastics and fuels disclosed in co-pending U.S. patent application Ser. No. 12/610,331, filed 1 Nov. 2009 (Nov. 1, 2009). Fuels may be stored at the cement plant in fuel storage containers, and fed into a fuel mill via a fuel feeder. Gaseous fuels, such as natural gas, may also be used as fuel. Gaseous fuels may be piped to the kiln, and regulated by valves or other suitable flow regulation means. A quality control operator generally monitors the rates at which fuels and raw materials are fed to the kiln.
The composition and properties of the raw materials and fuels determine the final composition of the cement clinker, and contribute to the overall efficiency of the cement system. For example, the raw materials and fuels each have a certain moisture percentage, indicative of the amount of water present. Further, the raw materials each have an associated loss factor. The loss factor is indicative of the amount of water, CO2 and organic matter that exits the raw material as it reaches the high kiln temperatures. Each fuel has an associated heat value and ash factor. The heat value is indicative of the amount of heat the fuel will produce in the kiln. The ash factor is indicative of the amount of fuel ash passed through from the fuel to the final cement clinker composition.
While many cement plants, systems and methods for making cement have been implemented and are currently being developed, there is a need in the art for cement plants, systems and methods for making cement that integrate a subsystem adapted to receive and convert used healthcare materials into a burnable fuel for cement production.
SUMMARY OF THE INVENTION Embodiments of this invention relate to systems for preparing cement including a cement raw material supply and conditioning subsystem, a burnable fuel supply subsystem, a kiln subsystem, and a cement storage and distribution subsystem. The burnable fuel supply subsystem is adapted to receive healthcare materials (used and/or unused) to produce an input burnable fuel having a desired component makeup. The burnable fuel supply subsystem may also be adapted to pre-process all or a portion of the healthcare materials (used and/or unused) and/or the input burnable fuel to produce a pre-processed burnable fuel. The burnable fuel supply subsystem may also be adapted to size or size and partially or completely homogenize all or a portion of the initial burnable fuel and/or the pre-processed burnable fuel to form a composite burnable fuel comprising a particulate burnable fuel component and optionally the input burnable fuel and/or the pre-processed burnable fuel. The burnable fuel supply subsystem may also be adapted to shape all or a portion of the particulate burnable fuel into a compact shape to form a shaped burnable fuel. The input burnable fuel, the pre-processed burnable fuel, the particulate burnable fuel and/or the shaped burnable fuel are then supplied to the kiln subsystem as a sole fuel or a component fuel. The burnable fuel supply subsystem can also include sources of conventional gas, liquid or solid fuels such as coal, coke, natural gas, liquid hydrocarbons or other conventional fuels and include supply components for supplying the conventional fuels to the kiln subsystem.
Embodiments of this invention relate to methods for making cement including supplying a cement raw material to a kiln subsystem, where all or a portion of the cement raw material is conditioned prior to introducing the raw cement material into the kiln subsystem. The methods also include forming an input burnable fuel from one or a plurality of healthcare materials (used and/or unused) in a burnable fuel subsystem. The methods also include supplying the input burnable fuel and optionally a conventional fuel to the kiln subsystem. The methods also include heating and sintering the cement raw material and the fuel ash into a cement clinker composition in the kiln subsystem using the fuel supplied to the kiln subsystem by the burnable fuel subsystem. The methods can also include conditioning all or a portion of the cement raw material to form a conditioned raw material, all of which is supplied to the kiln subsystem to produce the cement clinker composition. The methods can also include pre-processing all or a portion of the input burnable fuel to form a pre-processed burnable fuel. The methods can also include sizing all or a portion of the input burnable fuel and/or the pre-processed burnable fuel in a sizing or sizing and partially or completely homogenizing subsystem to form a particulate burnable fuel. The methods can also include shaping all or a portion of the particulate burnable fuel into a shaped burnable fuel. The methods can also include containerizing the particulate burnable fuel and/or the shaped burnable fuel prior to supplying the fuel to the kiln subsystem. The methods also include supplying a burnable fuel to the kiln subsystem, where the burnable fuel comprises the input burnable fuel, the pre-processed burnable fuel, the particulate burnable fuel, the shaped burnable fuel, the containerized particulate burnable fuel and/or containerized shaped burnable fuel, in any mixture or combination, and where the burning of the mixture is adapted to supply sufficient heat for proper kiln operation and where the resulting ash contributes advantageously to the resulting cement clinker composition.
Embodiments of this invention relate to systems and methods for making cement and to cement compositions derived therefrom, where the system includes a raw material supply and conditioning subsystem, a burnable fuel supply subsystem, a kiln subsystem, and a cement storage and distribution subsystem. The burnable fuel supply subsystem takes in one or a plurality of healthcare materials (used and/or unused) to form an input burnable fuel.

For embodiments of the fuels derived from the present invention that are designed to be formed or shaped into a consolidated structure such as a pellet, the used or waste material compositions include an effective amount of binding agents, sufficient to permit the shaping to maintain its final shape. The binding agents are selected from the group consisting of polymer materials that have a melting or softening temperature between about 40° C. and about 150° C. In certain embodiments, the binding agents are polymer components in used or waste material having a melting or softening temperature between about 40° C. and about 150° C. Exemplary examples of such polymeric materials include, without limitation, modified cellulose, fabrics, plastics, thermoplastics, thermoplastic elastomers, elastomers, fiber enforced resins, metalized or metal coated plastics or polymers, or other polymeric materials and mixtures or combinations thereof.

Depending on their use, the compositions of this invention can be tailored to meet any desired need. By controlling the relative amount of combustible materials and non-combustible materials in the input burnable fuel, properties of the fuel can be adjusted to produce a desired fuel composition and a desired ash composition. Such input burnable fuel properties include, without, limitation, a fuel value, a burn rate, a flow rate, an ash composition, an ash weight, by-product compositions and types or any mixture or combination ofproperties. Other materials can be included to tailor or control fuel properties or to control the ash formed upon burning of the fuel. The fuel value can be adjusted up or down by changing the mix of combustible present and non-combustible materials.

Example 2 The following data was obtained from a pilot plant facility, where used or waste material was disinfected and shredded to form a burnable fuel and an ash obtained from burning of other used or waste material were burned and the resulting ash analyzed.
Disinfected shredded samples were received in 2.5 gallon buckets and were non-homogeneous at the one gram sub-sample size. Samples were shredded for particle size reduction. Coarsely milled and finely milled sample splits were returned and showed some inhomogeneity. The more finely milled sample split was utilized for all analyses.
Due to sample inhomogeneity, all analyses were performed multiple times (duplicate minimum) and values reported as represent “best value” averages. All data were reported on a finely milled sample weight basis.
Samples were stage ashed to 750° C. and held at temperature for 8 hours for ash percentage determination. After weighing, ash residues were fused with lithium metaborate for ash component analyses.
Metals except for mercury were determined by ICP-AES and ICP-MS after total sample decomposition with mixed acids including hydrofluoric acid or by high temperature fusion of sample ash with lithium metaborate. Mercury was determined by combustion/amalgamation cold vapor atomic absorption.
Bromide, chloride, nitrate, sulfate, and ortho-phosphate were measured by ion chromatography on washings from oxygen bomb combustion, and do not necessarily represent elements in these oxidation states prior to combustion.
Higher heating value is the gross calorific content and has not been corrected for possible sulfur content according to ASTM D5865.
The incinerated ash had a BTU/lb value of 5321 (12,377 MJ/kg) resulting in a 49 wt. % residue after burning at 750° C. The resulting ash had an elemental analysis tabulated in TABLE II.
