CTEC 1391 Test Prep Explain the function of an I/p in a control loop. What usually connected to - ✔✔Flow transducer converts to (4-20mA) signal from the controller to (3-15psig) pneumatic signal which sends the valve to open or close What would the pump system control valve would do if HV-201 were to close - ✔✔Open the bypass which is HV-202 If the flow transmitter (FT-102) in the tank system would have faulty reading of 0 the tank level on LIC-101 would change by - ✔✔Everything would increase If the flow transmitter (FT-102) in the tank system would have faulty reading of 0 the flow through FIC-101 would change by - ✔✔Would not change If the flow transmitter (FT-102) in the tank system would have faulty reading of 0 the output signal on LIC-101 and the setpoint of FIC-103 would change by - ✔✔FIC-102 would close If HV-101 were to fail in the tank system the output signal on LIC-101 and flow of FIC-102 would change by - ✔✔It would decrease. Explain the purpose of the reboiler and how it works - ✔✔Shell of tube of the reboiler and heats the thermoil Explain the purpose of reflux - ✔✔Vapor comes up to the top cools down the temperature turns it to liquid. If feed were to increased to the tower what would happen to the thermoil flow - ✔✔It would go down If the preheater temperature were to increase in SPM 700 how would the reflux flow valve (FV801) and (AI-801) change - ✔✔It would go up, and get hotter, would vapor more, TIC-308 increase temperature, FV-801 should open up Lost of cooling water in SPM 700 to the condenser how would (FV-802) change - ✔✔Decrease flow, cooling water to the drum, Combination reaction - ✔✔A+B-->C Decomposition reaction - ✔✔C->A+B Single Replacement reaction - ✔✔AB+C->AC+B Double Replacement reaction - ✔✔AB + CD --> AD + CB If a reaction is exothermic and we want to keep the temperature constant, what must we do - ✔✔Cool the reactor A stirred tank reactor reacts M+N>O M and N are both flow controlled into the reactor and the reactor is level controlled by letting the product out If M is limited reagent which is most effective increasing production rate of O - ✔✔Increasing flow of M by 5% If I increased the temperature of a reactor by 10 Cel would reaction go faster or slower - ✔✔Faster, higher the temperature faster the reaction. If I had a highly exothermic reaction and needed to remove a lot of heat effectively what type of reactor would be best. - ✔✔Tubular (quicks to transfer heat) Name three ways you could increase the conversion in SPM 2100 - ✔✔Increase the temperature setpoint Increase the speed mixture Increase the flow rate of reactant A to B If the agitator speed in SPM 2100 is increased which direction would you expect TIC 223 output to change - ✔✔Decreases the output to open the valve If the agitator speed is increased in SPM 2100 which direction would AI-223 change - ✔✔It would increase If the agitator speed is increased in SPM 2100 which direction would FIC-211 output change - ✔✔There would not be a change Why does increasing the flow of reactant A require less cooling / more heating if the reaction is exothermic - ✔✔Would cause more heating Doing Laundry batch or continuous - ✔✔Batch Brewing coffee batch or continuous - ✔✔Batch Propane burner on grill reacting propane and air batch or continuous - ✔✔Continuous Traffic flow at stop light batch or continuous - ✔✔Batch Traffic flow at traffic circle batch or continuous - ✔✔Continuous Burning fuel inside cylinder of 4 stroke gasoline engine batch or continuous - ✔✔Batch Burning fuel inside a gas turbine jet engine batch or continuous - ✔✔Continuous
