Does a crude preheat exchanger help reduce emissions?

A crude preheat exchanger helps reduce emissions because it recovers heat from hot refinery process streams and uses that heat to warm the incoming crude oil before it reaches the fired heater.

When the crude oil enters the heater at a higher temperature, the furnace needs less fuel to reach the required distillation temperature. Lower fuel consumption means:

• lower CO₂ emissions

• lower NOx emissions

• lower flue gas volume

• improved overall refinery energy efficiency

It also reduces wasted heat in the process, which makes the crude distillation unit more thermally efficient.

In simple terms, a crude preheat exchanger helps reduce emissions by cutting furnace duty and reducing the amount of fuel burned in the refinery.
