Coal burning waste gases, notably carbon dioxide (CO2), can be removed or sequestered, and the distribution and utilization of coal as a safe, efficient, and convenient heat source can be improved. Carbon dioxide, a waste gas as from a coal burning process, can be sequestered within freshly fractured rock particles, such as Oligocene rock serpentine, using an adapted version of a rotary collider to fracture down hens-egg sized incoming rocks in a pressurized waste gas. The process sorts the small, fractured rocks and coats them after CO2 sequestration with a cementitious coating for use as a component of building material. In order to improve the transport and delivery of mined coal it is an advantage to fracture the coal and coat the particles with an aqueous liquid. The methods and apparatus deal with the improved delivery of said liquid-coated coal particles for current and new customers who become interested in using coal as an economical heating fuel.
A manufacturing process wherein rock, such as the Oligocene rock serpentine, is fractured without substantial wall grinding pressure in the presence of a pressurized flue gas, such as CO2, so that the flue gas may gain entry into the interior recesses of the fractured rock.
A manufacturing process wherein an array of high pressure gas jets serves to sort particles by size so that only smaller particles of a suitable size can emerge from the fracturing operation and the rest continue to be fractured into smaller pieces.
A manufacturing process where competing streams of high speed rock particles are mixed so as to reduce their velocity in a compact vessel by comparison to the usual “bag house” which requires much volume and heavy maintenance.
A manufacturing process wherein flue gas such as CO2 is preferentially encouraged to enter recently fractured rock by addition of ultrasonic energy without resorting to liquid intermediary substances.
A manufacturing process which forms a cementitious coating over the recently fractured rock so as to seal in any sequestered flue gas.
A manufacturing process which forms a cementitious coating over the recently fractured rock which makes the coated rock suitable as a valuable building trade byproduct.
A coal processing process which employs a rotary collider to provide small particles, nominally of 0.005 inch size, for efficient sorting out of impurities, such as clay and inorganic sulfur.
