SCRUBBER OPERATION

sop's related to scrubber:

1.operation of BF3 scrubber
2.operation of ammonia scrubber
3.operation of H2S scrubber
4.operation of HCL/acid scrubber
5.operation of cl2 scrubber
6.operation of PCL3 scrubber

scrubber media solution reacts with gas forming salts.

eg: HCL+NAOH --------->NaCl +H2O

H2S+2NAOH ------->Na2S+2H2O


  • Scrubbers are commonly used in process air application to eliminate potentially harmful dust,gas and pollutants.
  • A liquid in general water added with active chemicals suitable to the process is sprayed into the air flow.
  • Scrubber systems are a diverse group of air pollution control devices that can be used to remove come particulates and or gases from industrial exhaust streams.
  • The exhaust gases may contain substances considered harmful to the environment,and it is the job scrubber to either remove those substance from the exhaust gas stream or to neutralize those substances so that they cannot do harm to the environment/peoples as part of the exhaust stream.
  • scrubber is made with fiber reinforce plastic(FRP)
  • scrubber is connected with blower 
  • blower will struck the pollutant gas stream from process equipment and send to scrubber.these gas are scrubbed with suitable scrubbing media (water or water+NaOH)
  • to scrub the pollutant stream perfectly,resident time and restricted flow is required.for this packing rings are using the scrubber.
  • once scrubbed solution reached saturation point,change the scrubber solution.
commonly generating /escaping gases:
1.ammonia ---->base
2.H2S ---->weak acid 
3.co2----->acidic 
4.co------>acidic 
5.BF3----->acidic 
6.cl2------>acidic

THEORITICAL YIELD VS ACTUAL YIELD

Image
THEORITICAL YIELD VS ACTUAL YIELD : Amounts of products calculated from the complete reaction of the limiting reagent are called  theoretical yields , whereas the amount actually produced of a product is the  actual yield . The ratio of  actual yield  to  theoretical yield  expressed in percentage is called the percentage  yield

REACTOR Types of reactor :ssr,glr,hastolly reactor Types of condensers :sheel and tube Types of jackets: shell and limpet type Moc: ss316,ss316 contains 16-18%chromium and 11-14% nickel and remaining iron. ss reactor suitable for pH 7.0 to 14 and glr suitable for pH 1.0 to 7.0 Types of agitator s:anchor,propeller,turbine Baffles: paddle type baffles,using onside and two opposite sides in reactor Reactor capacity and part : as per batch size and urs   1.motor 2.gear box 3.agitator 4.bottom value 5.jacket 6.temperature sensor 7.safety value 8.nitrogen line 9.manhole or hand hole 10.flame arrester 11. reflux line Guages: 1.pressure guage: Measured the unit of forcesurface area.pressure is measured in kg/cm2 or lb/cm2 2.vacuum guage :A vacuum is a space in which the pressure of a gas is low compared to the atmospheric pressure. The measure of vacuum is associated with pressure. Vacuum gauges and instruments are used in conjunction with vacuum senso...
