WebDec 1, 2008 · The countercurrent packed-tower type air stripper offers greater interfacial surface area for mass transfer of volatile organic compounds than other gas-stripping processes. This method... WebThis could especially be true if the downcomer is a packed column to aid in gas stripping. This tower packing could get plugged. Hydrocarbons flashing out of the reboiler could cause disturbances. Too much stripping gas could cause disturbances. If sweet gas is used in the accumulator to prevent oxidation, the vent line could be improperly ...

WebSteam Stripping Pros and Cons. Like air stripping, steam stripping also has several pros, such as: High removal rates: Steam strippers achieve high removal rates and low effluent concentrations. Like air strippers, they can also eliminate 99% of VOCs. Minimal emissions: The steam stripping process reduces air emissions and load incineration. WebHydrogen sulfide (H 2 S) is an odorous gas that can be stripped from a water solution in a gas stripping tower. In this tower, the contaminated water is allowed to trickle downward over slats or corrugated surfaces while clean air is blown in from the bottom, aerating the dripping water. The reaction is: WebCorrosion occurred in an absorber tower, 18 m (60 ft) tall and 2.6 m (8.5 ft) in diameter, in which liquid monoethanolamine removed hydrogen sulfide from gaseous propane and butane.After four years of service, the base of the column was replaced without any postwelding heat treatment. Two years later, a Monel liner was fitted to reduce corrosion … labaran ganduje kano
