Process Applications of mist eliminators
Equipment selection Guide
When the vessel size is not set through the mist eliminator, like normally occurs in the case of distillation towers, steam drums or evaporators, practically the first step is using the wire mesh pad kind. Demister mesh mist eliminators offer excellent separation efficiency at the nominal installation cost.
When the vessel size is set by mist eliminator, the advantages of high capacity mist eliminators is becoming the most affordable solution. The fouling resistant special alloy mesh mist eliminator generally provides the best solution if the mist includes solid particles, viscous, sticky liquids, or the large sluges of liquid take place.
In the intense debottlenecking solutions or in new designs at very large functional operating pressures where it is essential to decrease the vessel size and weight, the high capacity features of demister mist eliminators often prove to be advantageous.
Mist eliminators are the sole type which significantly eliminate submicron size particles.
Applications
Refineries
Mist eliminators in the fractionators increase the throughout capacity and allow cuts for higher outputs.
Petrochemical Plants
Mist eliminators are utilized in the interstage knock-out drums of the compressor trains to increase compression run length and operation life.These are also utilized in the cooling towers to avoid contamination and secure downstream device.
Flue gas desulfurization
High capacity, low pressure drop mist eliminators offer outstanding resistance to fouling.
Gas Absorption systems
Designers and operators of gas absorption systems utilzie glycols, amines, and other proprietary solvents to eradicate water vapor, hydrogen sulfide, carbon dioxide or other contaminants from the gas streams. Although, these generally implement the equipment specifications that have not been evaluated to decrease losses of these costly chemicals. The losses can be caused from the various reasons such as:
1. Carry over losses of absorption chemicals with the processed gas.
2.Entrainment losses in the overhead gas from the reproduction towers
3. Foaming caused by liquid hydrocarbon entrainment into the absorber.
Sulfuric Acid plants
Well designed mist eliminators are crucial to the economical operations in all sulfuric acid plants. In the drying, moderate and eventual absorption towers, badly functioning mist eliminators add to the corrosion of ducting, blowers, heat exchangers and vessels. The stack emissions can cause environmental non-compliance and significant closures.
Our engineers are very well familiar with the special design factors needed for sulfur burning, ore roasting and sludge burning units. We offer the advanced technology in increasing efficiency, protection, performance life and capacity of mist eliminators.
