Pinch Analysis for Oil Refining

Refinery debottlenecking uses pinch analysis and heat integration to boost throughput, cut heater duty and avoid major plant expansion.

Pinch Analysis helps refineries cut fuel, steam and power costs by recovering process heat, lowering emissions and meeting refinery BAT energy targets.

A 2021 CDU retrofit cut energy use 8% through crude preheat train optimization, reducing refinery fired-heater fuel gas and stack emissions.

Refineries use a 20-40°C minimum approach temperature to balance fuel savings, exchanger area, fouling risk and crude preheat run lengths.

Cut refinery emissions by up to 25% with CDU pinch analysis. Optimise crude distillation unit preheat trains to lower fuel use and utility costs.

Identify refinery preheat train retrofits with payback under 0.75 years. Compare Aspen and HTRI heat integration software for MINLP and Pinch Analysis.
