Crude Distillation Unit Pinch Analysis Results for Heat Exchanger Network Optimization

Abubakar Sadiq Isah of the Federal University of Technology Minna published a paper comparing HINT software and nonlinear programming for pinch analysis. The study calculated a minimum total annual cost of $4.88 million/yr for a crude distillation unit's heat exchanger network, with specific hot and cold utility requirements. The HINT package's solution was within 1 percent of an existing solution for minimum area target.

Use Cases

• Benchmarking process integration software performance based on the comparison between HINT and nonlinear programming techniques.
• Optimizing heat exchanger network design based on calculated utility requirements and minimum total annual cost.
• Validating pinch analysis methodologies for crude distillation units based on the reported energy recovery and cost figures.

Strengths

• Includes specific quantitative results: hot utility required is 4.99 x 10^8 kJ/hr, cold utility is 5.08 x 10^8 kJ/hr.
• Reports key optimization parameters: a ΔTmin of 2.95K yielding a total annualized cost of $4.88 million/yr.
• Provides a performance benchmark, stating the HINT solution was within 1 percent of an existing solution.
