Vapors
The term vapor describes a gas that is still interacting with its liquid or solid phase. A vapor is different from smoke – a gas with minuscule solids – and fog – condensed steam.
In many industrial applications, vapors are often a by-product of thermal production processes, like for example die casting or thermal textile finishing. These vapors usually contain harmful or toxic impurities. These impurities can be oily or pasty aerosols, as occurring during the die-casting process, or tarry droplets, which occur during the smoking or deep-frying process in the food production process.
In order to comply with regulations to occupational safety and environmental protection in accordance with national legal requirements companies need to implement exhaust air purification systems. However, conventional filtration system can quickly become clogged, requiring frequent maintenance and replacement. Exhaust air filtration systems by KMA Umwelttechnik are easily maintained and cleaned thanks to the integrated filter cleaning system CIP (Cleaning in Place). The CIP can be individually programmed, runs fully automatically and therefore contributes to the durability and constantly high separation efficiency of KMA exhaust air filtration system.
Each KMA filtration system consists of an energy-efficient electrostatic precipitator and can be extended by further modules for heat recovery or odor separation if required. The KMA exhaust gas scrubber is used for an efficient filtration of heavily contaminated vapors. The gas scrubber works according to the absorption principle – impurities contained within the vapor are bound using a rinsing solution and then extracted from the exhaust air stream.
In addition, the process waste heat bound in vapors can also be recovered. Using the KMA heat exchanger and the KMA thermal heat pump, the process waste heat is extracted from the exhaust air via a carrier medium and can thus be used for subsequent production processes.
