  • 2. 
    When would you activated the Reactor Emergency Stop?
    • A. 

      To reduce the reactor pressure

    • B. 

      When there is a leak on the clarifier inlet/outlet

    • C. 

      When there is a leak on EV201/EV251 bottoms vessels

    • D. 

      When there is a leak on the reactor or filter inlet and/or outlet lines

  • 3. 
    What does activating the Reactor Emergency stop do? 
    • A. 

      Dilutes the ACN concentration in the reactor and flushes the ACN line prior to going into safe shutdown

    • B. 

      Applies full cooling to the reactor via cooling water from the cooling tower

    • C. 

      Shuts the reactor inlet and outlet flows, then continues with the safe shutdown without flushing the lines

    • D. 

      Flushes the reactor feed line and then the outlet line to the filter

  • 4. 
    Selecting which option would be selected to Specifically reduce the reactor temperature back to it's set point?
    • A. 

      Safe shutdown

    • B. 

      Emergency cooling

    • C. 

      Emergency water flush

    • D. 

      Emergency shutdown

    What happens to the reactors when the temperature reaches 123°C?
    • A. 

      Copper Chloride dumps to reactor

    • B. 

      1000 litres of water is added to the reactor

    • C. 

      Full cooling onto all four jacket coils

    • D. 

      ACN feed and Catalyst charging interlocked, water feed onto reactor

  • 6.

  • 7. 
    What effect does vacuum have on a boiling liquid?
    • A. 

      None except water

    • B. 

      Causes polymer to form

    • C. 

      Increases the boiling point

    • D. 

      Reduces the boiling point

  • 8. 
    The following statment explains what happens when ACN is flashed off in the concentration columns, fill in the blank.ACN vapour flows through the primary and secondary condensers HE202/252, and then a knock back condenser HE204, the liquid the flows down a barametric leg into           .        
  • 9. 
    What are the two functions of copper nitrate on the ACM process
    • A. 

      Act as an inhibitor in the reactors to prevent an over reaction

    • B. 

      Acts as a co- catalyst and inhibits polymerisation in the luwas

    • C. 

      Prevents catalyst from reacting with the ACN

    • D. 

      Slows down the rate of reaction so more yield is achieved
