PINCH

Pinch is a methodology used to minimize the energy consumed in industrial processes by optimizing heat recovery. It identifies heat recovery opportunities by plotting the temperature curves of a process's hot and cold streams. The "pinch" is the point where the temperature difference between the hot and cold streams is smallest. This point is crucial as it determines the minimum amount of external energy required for heating and cooling in the process.

In other words, pinch analysis helps engineers design heat exchanger networks that use as little energy as possible, maximizing internal heat recovery.

MISSION

We were commissioned to reduce gas and fuel oil consumption, as well as production costs and CO2 emissions. To achieve this, we focused our research on recovering heat from ponds to meet part of the needs of one of the site's buildings.

The following points were examined:

• Analysis of basin flow and temperature data
• Heat recovery sizing
• Filtration required
• Adapting the existing network
