Pinch Analysis: Heat Exchanger Network Energy Recovery

Every industrial process has streams that need heating and streams that need cooling — and pinch analysis is the energy-efficiency method that figures out the minimum outside fuel and cooling water a plant actually needs once those streams trade heat with each other first. This simulator runs the real problem-table algorithm on a small four-stream process: two hot streams that must be cooled and two cold streams that must be heated, each with its own supply/target temperature and flow-capacity (CP). Adjust the minimum approach temperature and one stream's flow rate to watch the pinch temperature and the minimum hot/cold utility targets recompute live, and toggle heat integration on and off to see, in the 3D network and in the numbers, exactly how much energy cross-exchanging the streams recovers compared to heating and cooling every stream from scratch.
