Abstract: A method for treating a process water from a bitumen recovery process in order to obtain carbon dioxide from the process water, which method includes lowering the pH of the process water, thereby causing carbon dioxide to evolve from the process water as evolved carbon dioxide gas. The evolved carbon dioxide gas may be collected and compressed, and water vapour associated with the evolved carbon dioxide gas may be separated from the evolved carbon dioxide gas. After the carbon dioxide has been obtained from the process water, the process water and the water vapour separated from the evolved carbon dioxide gas may be recycled back to the bitumen recovery process. The evolved carbon dioxide gas may be stored for future use or sale. The method may also include heating the process water in order to reduce the solubility of carbon dioxide in the process water.

Abstract: The floor member is a laminated structure in the form a floor tile or a floor plank. A bottom portion of the floor member is formed with a plurality of moisture dispersal pathways that lead toward peripheral side edges of the bottom portion. The moisture dispersal pathways permit any moisture that develops between a floor base and the bottom portion of the floor member that is installed on the floor base to flow in the moisture dispersal pathways toward at least one of the peripheral side edges of the bottom portion, for passage beyond the one peripheral side edge of the bottom portion. Adjacent tiles of a floor tile installation have communicable moisture dispersal pathways such that moisture is not entrapped below the floor member and can migrate through the communicable pathways to an outermost peripheral side edge of the floor tile installation for dissipation of moisture into the ambient air.
