|20160083258||CO2 CAPTURING CALCINER - A system to calcine crushed carbonate, discharge alkaline oxide, and deliver an enhancing fluid having CO2, comprising: a pressurized insulated calciner having descendingly, a crushed alkaline carbonate feeder, a calciner fluid outlet manifold, a heated sideflow calciner fluid intake manifold, a preheated sideflow calciner fluid outtake manifold, a fluid inlet manifold to recirculate calciner fluid from the outlet manifold, and an alkaline oxide discharger; a pressurizer to repressurize sideflow calciner fluid, connected to intake and outtake manifolds; pressurizers to recirculate calciner outlet fluid to the inlet manifold, pressurize the calciner and deliver enhancing fluid comprising CO2; delivery and combustion systems to form a combustion fluid; a recuperating or regenerating refractory heat exchanger to heat sideflow calciner fluid with combustion fluid connected to the sideflow pressurizer, and fluid outtake and intake manifolds; and a controller operable to control combustion, heat exchange, calciner fluid formation and delivery, carbonate feed and oxide discharge.||03-24-2016|
|20150129208||CALCINER ENHANCED OIL RECOVERY - A method of supplying crushed alkaline carbonate from a carbonate resource to a first calcining site having a design calcining capacity; calcining the crushed carbonate within a prescribed carbon dioxide (CO2) delivery distance from a first enhancement location within a first hydrocarbon resource, whereby generating CO2 with a local CO2 generating capacity and an alkaline oxide; forming a first enhancing fluid comprising generated CO2 and delivering it into the first enhancement site having an injector well weighted first enhancement location, whereby mobilizing hydrocarbon in the first enhancement site; producing a produced fluid comprising mobilized hydrocarbon and enhancing fluid; recovering liquid hydrocarbon from the produced fluid; wherein the prescribed CO2 delivery distance is less than 67% of a remote CO2 delivery distance, to the first enhancement location from a remote calcining site having an equal or greater design calcined CO2 generating capacity. Then calcining CO2 to enhance a second larger site.||05-14-2015|
