GAS-LIQUID SEPARATION
Droplet Formation
The below table gives an overview of the different sources of droplet formation and an indication on the respective range of droplet size, as well as an overview of the efficiency of the different types of mist
DEFINITIONS OF WORDS AND PHRASES USED IN
SEPARATION EQUIPMENT
• Entrainment:
Fluid in the form of a mist, fog, droplets, or bubbles
carried along with the continuous phase
• Coalescing:
To come together to form a larger whole. The process or
mechanism of bringing small droplets or aerosols and
creating larger droplets that can more easily be removed
by gravity. Also refers to the joining of liquid droplets
dispersed in another immiscible liquid, as with water
drops in oil.
• Mist eliminator:
A fixed device used to enhance removal of smaller liquid
droplets from a gas above which is not normally possible
by gravity separation. Typical mist eliminator
designs include knitted wire mesh, vane type, and cyclonic.
Mist elimination internasls provided by InfluentSeparation
prove to be an effective solution to eliminate the droplet
entrainment problems in typical applications as follows:
• Gas and oil processing
• Refinery units (crude unit, FCC,SRU, alkylation)
• Environmental scrubber, absorption tower
• Evaportators,condensers
• Sulphuric acid
• Fuming acid mist removal
• Chlor-alkali
• Nitric acid
• Methanol,Ethylene
• Ammonia and urea
• Asphalt vent mist removal
• Lube oil mist removal
• Metalworking mist removal
• Pulp & paper
• .......
A wide variety of separation vessel styles
and devices are used in the natural gas
processing industry. These include vertical and
horizontal vessels, two and three phase, many
types of internals, as well as cyclonic devices,
filter separators, gas coalescing filters, and
gas and liquid filters.
