Techniques for locating and operating gasification plant having predominately scrap tire rubber as feedstock
A parcel of land on which to site the plant is identified. The parcel of land is located such that about 3,500,000 to about 7,500,000 scrap tires per year are available for substantially regular and substantially continuous delivery to the plant, at a tipping fee of at least about $40.00 per ton. The plant is located on the parcel of land. One or more of synthesis gas, electricity, and steam produced by the plant are sold.
1. A method for locating and operating a gasification plant employing predominately tire-derived fuel as a feedstock, said method comprising the steps of:
identifying a parcel of land on which to site said plant, said parcel of land being located such that at least about 3,500,000 scrap tires per year are available for substantially regular and substantially continuous delivery to said plant, at a predetermined adequate tipping fee;
locating said plant on said parcel of land;
operating said plant on said parcel of land by:
shredding at least a portion of said 3,500,000 scrap tires into pellets; and
gasifying said pellets to produce synthesis gas, by:
introducing said pellets into an updraft, fixed-bed gasifier; and
introducing into said updraft, fixed-bed gasifier, adjacent said pellets, at least one of air, oxygen, and steam;
flowing said synthesis gas in an updraft to a gas exit of said updraft, fixed-bed gasifier, during operation of said updraft, fixed-bed gasifier; and
selling at least one of said synthesis gas, electricity produced by combusting said synthesis gas, and steam produced by combusting said synthesis gas;
wherein said step of introducing said pellets into said updraft, fixed-bed gasifier comprises introducing said pellets at a rate of from about 7,990 lbs/hour to about 17,123 lbs/hour; and
wherein said step of introducing said at least one of air, oxygen, and steam into said updraft, fixed-bed gasifier comprises introducing air in sub-stoichiometric amounts;
wherein said identifying step comprises the sub-steps of:
generating a visual representation of a geographic region of interest, wherein said visual representation includes at least one window adjacent at least one tire supplier location;
superimposing over said visual representation at least one criteria object, comprising at least one of a point, a line, and an area; and
identifying said parcel as lying within said at least one window and proximate said at least one criteria object;
further comprising providing a system, wherein:
the system comprises distinct software modules, each of the distinct software modules being embodied in a non-transitory manner on a tangible computer-readable recordable storage medium, and wherein the distinct software modules comprise an image generation module and an overlay module;
said step of generating said visual representation is carried out by said image generation module implemented on at least one hardware processor; and
said step of superimposing is carried out by said overlay module implemented on at least one hardware processor.
2. The method of claim 1 , wherein, in said generating step, said at least one window comprises a circle having a radius of no more than about 150 miles.
3. The method of claim 1 , wherein, in said generating step, said at least one window comprises a circle having a radius of no more than about 80 miles.
4. The method of claim 1 , wherein said identifying step comprises identifying such that at least about 5,000,000 of said scrap tires are available per year to said plant.
5. The method of claim 1 , wherein, in said superimposing step, said at least one criteria object comprises a geographical region in which it is permissible for the plant to operate.
6. The method of claim 1 , wherein said at least one criteria object represents at least one of:
a roadway capable of delivering said tires to said plant;
a waterway capable of delivering said tires to said plant;
a railway capable of delivering said tires to said plant;
a sewer system capable of handling waste water from said plant; and
an adequate water supply.
7. The method of claim 6 , wherein said identifying step further comprises:
selecting said parcel of land to have an area of from about two acres to about six acres.
8. The method of claim 1 , wherein said step of identifying said parcel of land on which to site said plant comprises identifying said parcel of land such that it is located such that said at least about 3,500,000 scrap tires per year are available for substantially regular and substantially continuous delivery to said plant, at said predetermined adequate tipping fee, said predetermined adequate tipping fee being at least forty dollars per ton of scrap tires supplied.
