Plastic Random Packing Articles

Packed-bed Scrubbers

Packed-bed scrubbers consist of a chamber containing plastic random packing material, such as KemFlo’s Kempac plastic tower packing (Tripack, Pall Ring or Plastic Saddle), that provide a large surface area for liquid-particle contact. The packing is held in place by a bed limiter and supported by a packing support. Scrubbing liquid is evenly introduced through a liquid distributor located above the packing and flows down through the plastic scrubber packing. The liquid coats the plastic tower packing and establishes a thin film. The pollutant to be absorbed must be soluble in the fluid.In packed-bed scrubbers, the gas stream flows up the chamber (countercurrent to the liquid). Some packed beds are designed horizontally for gas flow across the packing (crosscurrent). Physical absorption depends on properties of the gas stream and liquid solvent, such as density and viscosity, as well as specific characteristics of the pollutant(s) in the gas and the liquid stream. These...

Corrosion Problems with Wet Scrubbers

Corrosion is one of the most challenging and costly issues seen across all markets worldwide. Billions of dollars are spent dealing with the effects and in the prevention of corrosion. Engineers are tasked with the job of designing in such a way that minimizes the effects of corrosion. Luckily there are many high performance materials and systems for engineers to utilize in their efforts to combat the effects of corrosion. Cost and material availability must be weighed against long term performance of a system. Air pollution control engineers must consider the following design criteria when designing wet scrubbing equipment:king.com. Technical performance: Does the unit consistently meet the specified air cleaning efficiency? Reliability: What are its weaknesses and how can we protect against damage or failure? Outage: How much of an outage can be tolerated without loss and how quickly can the unit be repaired or replaced? Cost: What is the most cost effective system?...

Water Treatment and Maintenance

The importance of developing a proper maintenance plan before an air stripper or scrubber goes into service can not be overstated. Protect the investment you made in your column by reducing or eliminating the affects that scaling and fouling has on plastic tower packing and internals.
