    Air stripping is the transferring of volatile components of a liquid into an air stream. It is an environmental engineering technology used for the purification of groundwaters and wastewaters containing volatile compounds.

  12. Lets make the list of software used by chemical engineers. Also suggest which software should learn during college days. please add software name and its application by replying to this post.
  13. From the album Process Flow Diagrams

    Introduction • Ethylene oxide is produced by the oxidation of ethylene using air. • Ethanolamines are produced using the series reaction scheme of ethylene oxide with ammonia. • Ethanolamines are significantly used as absorbents to remove CO2 and H2S from process gas streams. Reactions • C2 H4 + 0.5 O2→ CH2 O.CH2O • Ethylene to air ratio: 3 – 10 % • Side reaction products: CO2 , H2O • Catalyst: Silver oxide on alumina • Operating temperature and pressure: 250 – 300°C and 120 – 300 psi • Supressing agent for side reactions: Ethylene dichloride • Reaction is exothermic • Air and ethylene are separate compressed and along with recycle stream are sent to the shell and tube reactor. • The reactor is fed on the shell side with Dowtherm fluid that serves to maintain the reaction temperature. A dowtherm fluid is a heat transfer fluid , which is a mixture of two very stable compounds, biphenyl and diphenyl oxide. The fluid is dyed clear to light yellow to aid in leak detection. • The hot dowtherm fluid from the reactor is sent to a waste heat recovery boiler to generate steam. • The vapour stream is cooled using a integrated heat exchanger using the unreacted vapour stream generated from an absorber. • The vapour stream is then sent to the heat integrated exchanger and is then sent back to the reactor and a fraction of that is purged to eliminate the accumulation of inerts such as Nitrogen and Argon. • The product vapors are compressed and sent to a water absorber which absorbs ethylene oxide from the feed vapors. Eventually, the ethylene oxide rich water stream is sent to a stripper which desorbs the ethylene oxide + water as vapour and generates the regenerated water as bottom product. The regenerated water reaches the absorber through a heat integrated exchanger. • The ethylene oxide + water vapour mixture is compressed (to about 4 - 5 atms) and then sent to a stripper to generate light ends + H2O as a top product and the bottom product is then sent to another fractionators to produce ethylene oxide as top product. The heavy ends are obtained as bottom product.
