Open Source Chemistry Software

Balances any complex chemical equation easily. Version: v 1.0 and v 2.0 both are available.

TOPCEE (Toyese Oyegoke Process Cost & Economic Evaluator) is a GUI-based Python application designed to assist chemical engineers, researchers, and students in evaluating the profitability of chemical/process plants. The app calculates capital and operational expenditures (CAPEX & OPEX) and provides key profitability metrics such as: **ROI (Return on Investment) **IRR (Internal Rate of Return) **NPV (Net Present Value) **Payback Period (Discounted and Non-Discounted) **Benefit-Cost Ratios Users input plant-specific values like feedstock costs, operating time, product price, and equipment cost — and the tool generates real-time visualizations and results. TOPCEE is ideal for feasibility studies, academic research, and early-stage techno-economic evaluations.
