Heat Recovery in Chemical, Refining and Renewable Energy Industries
Implementing heat recovery exchangers in your production process will help to increase plant efficiency as well as decrease your energy costs and carbon footprint. Using a recovery heat exchanger and transferring heat into other process area is a basic method to increase production of the plant and decrease fuel consumption.
When working with steam or hot water applications, economizers save energy by capturing waste heat from boiler gases and transferring it back into the boiler feedwater.
Flue gas recovery exchangers also work with boiling systems to recover heat from waste flue gases and use it to preheat water entering the boiler. This reduces the energy consumed in warming up the water to the required level, increasing efficiency and delivering the same amount of heat to the boiler with 4% less gas.
Interchangers are shell and tube heat exchangers that often use one product stream to heat or cool another product stream, instead of using utility fluids as the heating or cooling medium. Hot product that needs to be cooled before distribution for packaging or piping, can be cooled down by another product stream that needs preheating before heading for evaporating stages. This takes the load off of a final cooler, potentially reducing the chiller size. It also reduces the energy needed for the final heater or evaporator, resulting in greater efficiency and energy savings for the plant.
