Vadose Zone Remediation of Carbon Dioxide Leakage from Geologic Carbon Dioxide Sequestration Sites

A system model for geologic sequestration of carbon dioxide.

In this paperwe describe CO2-PENS, a comprehensive system-level computational model for performance assessment of geologic sequestration of CO2. CO2-PENS is designed to perform probabilistic simulations of CO2 capture, transport, and injection in different geologic reservoirs. Additionally, the long-term fate of CO2 injected in geologic formations, including possible migration out of the target...

Sequestration of Carbon Dioxide Emissions

Background The world's oceans represent the largest potential sink for the carbon dioxide (CO 2) produced by human activities (anthropogenic CO 2). Already oceans contain the equivalent of an estimated 140,000 gigatons of CO 2. The ocean's natural carbon transfer processes span of thousands of years and will eventually transfer 80-90 percent of today's man-made CO 2 emissions to the deep ocean....

Reductive Sequestration of Carbon Dioxide

The United States currently meets 80% of its energy needs by burning fossil fuels to form CO2. The combustion-based production of CO2 has evolved into a major environmental challenge that extends beyond national borders and the issue has become as politically charged as it is technologically demanding. Whereas CO2 levels in the atmosphere had remained stable over the 10,000 years preceeding the...

Carbon Dioxide Sequestration In Alkaline Waste

The present study focuses on exploring an array of alkaline waste residues, procured from diverse sources as means for sequestering maximal CO2. Alkaline waste residues undertaken for the study included: (1) Cement Bag Filter Dust, (2) Finished Cement Sample, (3) Marble Dust and (4) Baghouse Dust. Experiments were conducted in a self fabricated Carbonation reactor under 80% CO2 concentration an...
