Project Oxygen Economiser Carbon Reduction Study
The underlying purpose for this project was to reduce the amount of carbon dioxide emitted from the oxygen heater exhaust stack in Tiwest’s KPP Unit 300, and also look at the opportunities for energy savings through heat recovery. Sargon Engineering looked at options for mechanical modifications to the oxygen economiser’s tapered vent stack, namely the introduction of a heat-exchange mechanism to modify the flue gas exit temperature. The favoured option was evaluated to provide a summary of the modified stack performance. Sargon Engineering also prepared a cost estimate to purchase and install this carbon reduction system.
Sargon Engineering provided calculations and extensive reasoning to support the basis of design. A 3D model was developed, along with detail drawings of the modified stack. In addition to the design and estimating work, Sargon Engineering submitted an assessment of the potential safety issues that might arise with the introduction of the stack modifications.
Sargon Engineering was able to give a coherent summary of the engineering rationale, the design features, and the cost implications for the introduction of a carbon reduction and energy recovery system. With all the quantities, figures and savings potential presented clearly in the final report, Tiwest was given the means to make an informed decision on whether the proposed system would be worth implementing. The project was delivered on time and on budget.
