Waste Heat Recovery

Waste heat recovery refers to recovering waste heat that a pipeline compressor station or an industrial site is emitting and turning it into a form of clean energy that is useful. A waste heat recovery unit is usually used to recover heat from streams with high energy content. Such hot streams includes steam from cooling towers, hot fuel gases from a diesel generator and waste water from steel cooling system.
The process that occurs in the waste heat recovery unit involves using the waste heat found in the exhaust gas of various processes to preheat incoming gas. These systems have turned out to be beneficial because efficiency of processes has resulted. It has also led to the reduction in air and thermal pollution, size of equipment and auxiliary energy consumption.
The waste recovery unit can be costly to use and furthermore the quality of waste heat recovered is usually low thus difficult to efficiently utilize.
