Classification: CPC C  B | IPC B  C

Claim 30:
31. The method of claim 1, wherein the burned organic matter comprises rice hull ash, wherein the clean water employs deionized water, wherein the rinse temperature is greater than or equal to 50° C., wherein the reaction pressure is greater than or equal to 200,000 pascals (2 bars), wherein the pressure-cooked reaction mixture or the preliminary sodium silicate solution travels through a heat exchanger to cool to a lower temperature, wherein the clean water flows through the heat exchanger before the step of contacting the ash, wherein the clean water is below the rinse temperature before the clean water flows through the heat exchanger, wherein separating the pressure-cooked reaction mixture employs a pressure differential greater than 20,000 pascals, wherein separating the pressure-cooked reaction mixture is conducted at a temperature of less than or equal to 125° C., wherein separating the pressure-cooked reaction mixture employs a post-reaction filter media that has a pore size of less than or equal to 2 microns, wherein separating the preliminary sodium silicate solution employs activated carbon, wherein the method has the capability to consume a minimum of 1,142 kilograms of rice hull ash per hour, wherein the target sodium silicate solution is heated to evaporate water, and wherein the evaporated water is employed in the step of contacting the ash.
