Green Technology

Geo-Processors USA has developed a Carbon Capture and Storage (CCS) technology, that it piloted in Australia.  The technology supports the efficient capture of CO2 from point-sources and converts it to mineral byproducts for industrial use or recycling.  Industries, such as oil and gas, mining, coal-fired utilities produce large volumes of bicarbonate-rich water, which increases their operational costs.  Geo-Processors Pty Limited is a private greentech company headquartered in Sydney, Australia.  ...

...   "A typical CCPR system commences first with treatment of the alkaline produced water in Geo-Processors’ proprietary SAL-PROC technology using cheap lime - or dolime - to generate a caustic spent water and a useful byproduct. The caustic spent water is brought into contact with CO2 of ambient air (or from a point-source) and then reacted  again with lime to regenerate calcium carbonate and an alkaline water which is suitable for the next round of CO2 capture.  This system is a closed-loop system because beyond the first reaction step a steady-state chemical situation is set up, thus enabling the repetition of the CO2 Capture-calcium carbonate precipitate cycle. Depending on the scale and number of cycles applied in each case, the spent water from  the last reaction step can be either treated in the SAL-PROC process to recover other valuable byproducts or converted to dry salt for landfill disposal.  The byproducts recovery steps may include production and recycling of calcium oxide. The co-generated high-grade CO2 gas from the calcining step may be partly used in the process for production of a high-value mineral product and the unused portion sold for other industrial applications or sequestrated.
