SO3 / OLEUM TANK VENTS
Oleum and liquid SO3 is stored in tanks and when the tanks are being filled or emptied, there is an increase in vent vapour. Similarly, when loading into or from trucks & wagons there will be a SO3 fugitive vapour. This SO3 vapour...

TANK CLEANING EMISSIONS
In chemical and petro-chemical plants there are various storage vessels for raw materials and for finished products. When some tanks require to be cleaned, there can be a risk of volatiles and other vapours escaping from the tank and causing unacceptable emissions.

The primary function of the boiler steam drum is separate water from steam which prevents carryover of the condensate into to the steam header (the separated steam is sent to super heaters and the water is recirculated for conversion to steam with a purity in the range of...

In many processes storage tanks hold raw materials or finished products which have air vents that need an abatement system for capturing volatile organic vapours. These contaminants can include organic compounds of nitrogen and sulphur (with bad odour), and other compounds containing carbon, hydrogen, and oxygen.

FLASH EVAPORATION
Flash Evaporation or Multistage Flash Distillation is a water desalination process to distil seawater by flashing the water into steam in multiple stages. Multi-stage flash evaporation plants produce about 60% of all desalinated water in the world, with the heat added in the brine heater usually...
