除雾器用来保护环境。洗气室中带出的液滴被有效地分离以达到排放要求。
烟气在排放到大气之前要进行清洗以去除其中的污染物。当今大多数的清洗工艺均采用湿式洗气或吸收，作为溶剂的液滴起清洗作用。
除雾器的任务就是阻止液滴喷射到大气中，以保护环境及下游设备如气体-气体热交换器等。为适应现在湿法洗气室和吸收塔对气体除污效率越来越高的要求，除雾器应能在更宽的工艺条件下运行。新建工厂或老厂扩建时对费用的最低化造成更高的气流速度，这就使除雾器面临更艰巨的任务。
蒙特的全球除雾器客户在过去的四十几年中已在数千个工程点应用了叶片式分离技术。.
对于所有已知的湿法洗气设施，蒙特公司提供完整的一系列分离系统以及服务。这包括单级，双级或三级分离系统，其中包含清洗系统及现场安装指导。

The DV210+ systems are built into the top section of the scrubber/absorber tower, primarily of a Flue Gas Desulphurization (FGD) plant.
The DH 2100-FGD (T 100) is a vane type droplet separator for horizontal gas flow direction, typically used in a panel design in the horizontal duct section of FGD absorbers.
The DV 880 (8800-Series) mist eliminator is a vane type separator for vertical gas flows. The DV 880 is typically used as 2-stage mist eliminator for medium to high liquid loadings
The DV 270 (T 271) droplet separator is a vane type separator for vertical flow. Used in evaporators, absorbers, gas scrubbers, desulphurization units, gas coolers, exhaust air treatment plants and chemical plant the DV...
DS 8000 is a series of spin vane separators removing droplets for both vertical and horizontal gas flow. The DS 8000 series avoids stack raining efficiently. Compared to other possiblities the spin vane separators are a...
