Community concerns led to pressure to adopt air emissions abatement technology for a major oil sands operator. Technical and economic decision support was needed to select an optimum abatement option for their cogeneration facilities.
A project owner was evaluating an enhancement to a project which would reduce air emissions (nitrous oxides / NOx) from their cogeneration units. The cogeneration units were providing process steam, on-site electricity, and grid export of electricity. The client required technical and economic decision support to understand the impacts of applying post-combustion treatment in order to reduce these emissions.
Advisian applied a structured process for decision making, which included the following steps:
The options modelled represented a range of possible air emissions outcomes, and included:
The client used Advisian’s expertise to compare not only the financial costs of the options (e.g. capital, operating costs, chemicals, fuel, water usage), but also the monetized social costs of NOx emissions, greenhouse gas and particulate matter (PM) emissions, byproduct formation and land disturbance footprint.
Advisian’s structured process and expertise delivered a clear, defensible business case comparison of abatement options for the client, which included a convincing positive outcome for external stakeholders.
Specific findings included:
