Computer-Aided Scaleup Process Integration, Economic Feasibility And Uncertainty Evaluation Of Bioclarified Water Recovery From Petroleum Waste Water:- Osoh, Kufre A

ABSTRACT

This study presents ASPEN Base Case Simulation (ABCS), preliminary process design with filtration integration, techno-economics and uncertainty analysis of bioclarified water production from petroleum wastewater. ABCS, scale-up design and economics were performed using inherent design and costing algorithms in ASPEN Batch Process Developer ' (ABPD) V10. The process profitability indices such as Net Present Value (NPV), Internal Rate ofReturn (IRR), Return on Investment (ROI) and Payback Time (PBT) were evaluated in a user-defined developed Microsoft-excel version 2018. Predictive models for predicting and optimizing techno-economic parameters: return on investment (ROI), payback time (PBT) and production rate (PR) were achieved in RSM via Box-Behinken Design (BBD) technique of Design Expert V13. The regression models gave R2 values of 0.9984, 0.9920 and 0.8867 for return on investment, payback time and production rate respectively. Monte • Carlo Simulation in Crystal Ball Oracle software was used to perform the profitability sensitivity and uncertainty analyses. The annual production target (600,0001itres/year) scaleup simulation results gave batch size 4061itre/batch, annual number of batches produced 1469batches/year. Base case capacity results showed that the total capital investment, NPV, IRR, ROI and PBT are $631485, $68932.18,9%, 15.8% and 6.33yrsrespectively. Sensitivity analysis shows that selling price has the highest contribution for both the NPV and the IRR respectively. The certainty ofthe base case model after 30000trials was 99.98% for NPV, 90.89% for IRR and 61.23% for production rate. This study showed that petroleum • wastewater BFS scale-up design is feasible
