Process Economics Estimator Skill

Purpose

The Process Economics Estimator Skill performs economic analysis of chemical processes including capital cost estimation, operating cost calculation, and profitability metrics.

Capabilities

  • Capital cost estimation (factored, equipment-based)
  • Operating cost calculation
  • Raw material cost analysis
  • Utility cost calculation
  • Labor cost estimation
  • Depreciation and taxes
  • Profitability metrics (NPV, IRR, payback)
  • Sensitivity analysis
  • Monte Carlo simulation

Usage Guidelines

When to Use
