Drop-stop

DROP-STOP is a modern impact drift eliminator of the for the separation of liquids from aerosol. DROP-STOP is typically used in:

  • Gas washing and/or adsocbers
  • Dehumidications of gases and/or vapor

DROP-STOP offers the indicated performances when:

  • It is installed with a minimum inclination of 45° on the level. However it is advisable to install it vertically, refer the attached diagram.
  • The gas stream flows in through the module regularly, without turbulence and at uniform speed.
  • There are no preferencial ways.
  • It is advisable that the drift eliminator be easly removed for control and maintenance operations.

DROP-STOP is a modern impact drift eliminator of the for the separation of liquids from aerosol. DROP-STOP is typically used in:

POLYPROPYLENE

LENGHT = 215 mm
WIDTH = 205 mm
HEIGHT = 198 mm
USEFUL SURFACE = 0,043 mq
WEIGHT OF ONE UNIT = ca. 1,3 kg

PVC

LENGHT = 500 mm
WIDTH = 500 mm
HEIGHT = 200 mm
USEFUL SURFACE = 0,250 mq
WEIGHT OF ONE UNIT = ca. 2 kg

By properly combinig the modules one can obtain drift eliminator of the desired dimensions with multiple surface of 0,043 sq. m. On request the drift eliminator DROP-STOP can be supplied assembled.

The efficiency oconsidered as a percentage of liquids removed from aerosol, depends on many elements, we which the main:

  • Dimensions and concentration of drops at the entrance of the module.
  • Temperature and viscosity of the phases which compose the aerosol.
  • "Maximum capacity" or "entrance speed" for the loading of the module.

For air/water aerosol at ambient temperature and pressure, the efficiency of the drift eliminator is shown in the diagram.
A "normal" target is to keep drops with a diameter equal or smaller than 50 micron. In this case the water leak in the in the liquid phase is more or less 0,4 0,5%. (per thousand) of the useful water flowrate for air washing. That is what happens provided the device is correctly installed.

Also the load loss depends on the already mentioned factors. As to the yield of water/air aerosol (under pressure and at ambient temperature), load losses are shown in the following diagram. The diagram shows (with ± 15% tolerance) only DROP-STOP drift eliminator load losses. Load losses due to other causes are not included (tower and pack container geometry).
