Benefits of Marine Demisters

Demister is defined as a device that is fitted on vessels of vapor-liquid separator for enhancement of liquid droplets removal which is entrained in vapor steam. They either maybe mesh-type coalesce or vane pack or any other structure whose intentions is aggregating into droplets the mist which are heavy such that they can be separated from steam of the vapor.

Demister are most referred for use in places vapor quality is of high importance in terms of the entrained liquids specifically where the costs of separator equipment are high or elsewhere weight or space saving are of advantage. For example, marine demister which is used in marine vessels during the brine desalination process. During this process, brine is converted to vapor through flash-heating. In the flashing, vapor picks over brine droplets which are subjected to separation before condensation to avoid salt contamination of the distilled vapor. Distilled vapor then condenses on desalination plant tubes then the resulting water gets collected in distillate tray. Marine demister are either vane demister or wire mesh demister. The marine demister offer beneficial functionalities.

Benefits of marine demisters include:

The core benefit is capturing any mist formed on the marine vessel in such a way that once the vapor steam that is carrying liquid droplets that are entrained pass through eliminator pad of the demister by Igiantech, the vapor gets to move through freely and an inertia is caused which makes the droplets contact coalesce and wire surfaces hence draining as big water droplets.

  • Reduction of valuable chemicals loss.
  • Increasing capacity of throughput.
  • Improving purity of products.
  • Contamination elimination.
  • Provision of protection for equipment.
  • Prevention of air pollution.
  • Highly efficient for drops of low pressure.
  • Cost-effective option for equipment with set requirements.

Demister is capable of reducing time of residence that is required for separation of given droplet size of liquid by cutting down the volume and any associated cost to the separator equipment.

  1. Wow that was strange. I just wrote an really long comment but after I clicked submit my comment didn’t appear. Grrrr… well I’m not writing all that over again. Anyway, just wanted to say excellent blog!

  2. THE NUMBERS GAME – KIERAN GILL: Three years ago, Mata was cast aside at Chelsea and told he could find a new club. Now under the Portuguese manager at Manchester United, that’s changed. Juan Mata and Jose Mourinho have buried the hatchet and the Spaniard is pivotal to Manchester United’s success this season

  3. certainly like your website however you need to test the spelling on several of your posts. Many of them are rife with spelling issues and I to find it very bothersome to tell the truth nevertheless I’ll certainly come again again.
