Abstract

A feasibility study comparing GHG and landfill disposal impacts of two processes: a traditional warm lime softener in a SAGD produced water treatment plant versus a pilot-scale sorbtion tower technology. The COSIA supported software named CO2Cepts was used to simulate both processes to attain a high level mass, water and energy balance for a 33,000 BPD operation. Data values for the software simulation were taken from literature reviews of journal articles, AER applications and the pilot‐scale testing data. Results show that the pilot scale technology was able to reduce landfill costs by 121,827tn/yr equating to 7.5Megatonnes/yr of waste diverted by 2040. Another finding was a small indirect GHG emission reduction of 37 CO2eq tn/yr/33,000 BPD operations, which equates to $1860/yr of carbon levy savings for the lime sludge disposal component. This could equate to a reduction of 2360 tnCO2eq/yr by 2040 with a carbon levy savings of $117,950/yr industry-wide.

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
