MECS® Pilot Plants for Mist Elimination

 

For some unusual applications, a field trial of the Brink® mist eliminators is helpful in testing its efficacy. In certain cases, the process description, conditions and requirements may lead to the conclusion that the application is unique with unknown fiber bed mist eliminator service life and maintenance needs. DuPont Clean technologies has metal and plastic pilot plants available to evaluate application feasibility to give customers a better insight into final performance. For details on the MECS® pilot plant service, rental and associated clean-up costs, which vary depending on the nature of the process being tested, please contact us.  

MECS® Metal Pilot Plant

The MECS® Metal Pilot Plant is constructed of 316 stainless steel and consists of an inlet prefilter/cooling coil (may differ slightly depending upon application), a Brink® mist eliminator, and fan modules. The pilot plant is about 12 ft long, 4 ft wide, and 10 ft high, weighing 4720 lbs. It is fully instrumented for controlling and monitoring gas flow rates. It handles up to 450 ACFM gas flow.

MECS® Plastic Pilot plant

The MECS® Plastic Pilot plant consists of a Brink® mist eliminator module and a fan module.The unit is approximately 10 feet long, 4 feet wide, 10 feet high, and weighs 3500 pounds. It is instrumented for controlling and monitoring gas flow and handles approximately 450 ACFM gas flow. The pilot plant is constructed of ATLAC 382 resin and should be operated below 165 °F since the resin can deteriorate at any higher temperature.

Recommendation for sample stream nozzle sizing and location will be provided for the best performance, and the reliable data for full scale design. The pilot plant is supplied to customers where an assigned person will need to install, operate it, and collect the operating data as described in the instructions provided with the pilot plant.

FIBER ANALYSIS

The heart of MECS® Brink® mist eliminators is the collecting fiber. Fiber bed mist eliminator performance can be affected over time by fiber corrosion or by accumulation of plugging agents. DuPont Clean Technologies provides free fiber sample analyses for Brink® mist eliminator users to evaluate the condition of their fiber beds and to help predict remaining service life. 

There are a number of ways to collect fiber samples. One way is to take a few "pinches" off the upstream surface of the bed. Another option is to take a core sample if there is a need for a more in-depth evaluation.

If internal plugging is suspected, a fiber core sample can be taken which is a small round section of packing removed from the fiber bed. The entire depth of the bed is removed. Core samples are very useful in detecting the presence of plugging materials and the extent to which plugging materials have penetrated the fiber bed. A rubber cork borer ranging in size from about 3/8 to 1/2 inch in diameter (9 to 12 mm) is used to take core samples. A rubber cork borer can be obtained from a laboratory supply store. It is helpful to use a plunger to push the core sample into a test tube for safe keeping. After samples are taken, the resulting hole in the element should be carefully plugged using laboratory glass wool sometimes referred to as "angel hair".

Before sending fiber samples, a safety sample data sheet should be completed and sent to DuPont Clean Technologies for approval.

BRINK® MIST ELIMINATOR GENERAL TROUBLESHOOTING

 

Our goal is to help our customers achieve outstanding and trouble-free installation and operation with their Brink® Mist Eliminator products. 

DuPont Clean Technologies is the expert on all types of mists, be they in process gases, indoor air quality (metalworking systems) or air pollution. Effective troubleshooting begins when Brink® fiber bed elements are installed and operated by ensuring proper installation and operation at design process conditions.

Installation/Maintenance: Proper mist eliminator installation and maintenance is as important as designing the right mist eliminators for the job. An effective installation requires proper gasket selection, flat mounting surfaces, correct bolt tightening procedures, and proper liquid seals.

For maximum trouble-free service, it is important to select the proper gasket for the specific process. Correct installation also requires the correct bolt tightening sequence. Using the tightening method as outlined in MECS IMI (Installation & Maintenance Instructions) will guarantee proper gas tight seals. The MECS bolt tightening method ensures gaskets are compressed uniformly. Using power tools with improper tightening may distort element flanges especially when stiffer/thicker gaskets are used.

After installation, a smoke test is recommended for large installations with high efficient diffusion fiber beds to safeguard proper installation of gaskets and liquid seals. Details for the smoke test can be provided on request.

For proper installation, it is essential to establish liquid and gas seals. The Installation & Maintenance Instructions (IMI’s) should be carefully studied before installation and maintenance.

Key mist eliminator start-up check points
Key mist eliminator start-up check points
It is important to detect and correct problems early during mist eliminator installations before they become severe or out of control.

Issues to be aware of during mist eliminator installations include:

  • High pressure drop (or abnormal pressure drop)
  • Spitting (re-entrainment)
  • Opacity (visible stack plume)
  • High measured exit loading
Testing or troubleshooting methods
Testing or troubleshooting methods

A number of testing or troubleshooting methods can be used to evaluate the installation. They include:

  • Monitoring pressure drop and flow rate
  • Stick test
  • Physical inspection
  • View Ports
  • Smoke Test
  • Gas Sampling

 

By far the most important “trouble-shooting” or “trouble-prevention” method involves monitoring of mist eliminator performance on a regular basis and, if undesirable symptoms occur, conducting an evaluation to correct problems before they become severe. Monitoring mist eliminator performance involves maintaining accurate and complete operating records. Records should include inlet process conditions: gas flow rate, temperature, and pressure along with element pressure drop and liquid drain rate from the mist eliminator vessel.

Monitoring element pressure drop and gas flow rate over time verifies operation is in the correct range. Any significant deviation in pressure drop is likely to be accompanied by a deviation in collection performance. We recommend keeping a plot of normalized pressure drop (pressure drop corrected to design gas flow rate) versus time.

The pressure drop is measured by connecting a U-tube manometer filled with water (not mercury) between a pressure tap on the inlet (upstream) side of the mist eliminator and a pressure tap on the outlet (downstream) side of the mist eliminator. Typical element pressure drops will range from 4 to 20 inches water column gauge (100 to 500 mm water column). Make sure pressure taps are open.

Avoid measuring pressure drop by comparing the static pressures on both sides of the mist eliminators since small inaccuracies in readings are magnified when calculating the difference. (e.g., A 10% error in reading static pressure of -80 inches water column gauge (-2000 mm wc) translates into a 60% error in calculating a 12"wcg (~300 mm wc) mist eliminator pressure drop.)

Pitot tube stack readings using EPA test methods 1 and 2 can provide an acceptable measure of gas flow if a suitable location can be found in the ductwork.

Information on using other troubleshooting methods is available on request.

Mist Sampling Program

 

If simple tests and/or an inspection do not identify the problem, a mist sampling program may be necessary. The sampling method must include the separation of mist from any vapors in the process. This needs to be reviewed with the sampling company.

Other test equipment that can be used includes optical aerosol monitors and Dwyer flowmeters. Test laboratories are often used to evaluate condition of the fiber packing (see Fiber Analyses).
