Section Number Issue Number Origination Date Revision Date Ethanolamines/Glycol Ethers In Plant Training (IPT) :13 :1.4 :06-25-92 : 12-23-97 Section Test 13 Control Board Ethanolamines Finishing End Objectives/Answers: 1. State what type cooling tower water should be used on E-241. All fresh water. 2. Explain how the bottoms temperature control scheme works on T-240. Steam to feed ratio 3. State what you would do if T-240 bottoms percent water were .09. Increase the steam to feed ratio. 4. Explain what process variable would cause the pressure on T-240 to raise. State what should be done to correct this problem. T-230 bottoms temperature (tray #4) is too cool, ammonia in T-230 bottoms feed to T-240. Increase T-230 temperature control set point and flush VP-240 with fresh water. Also to much C02 in EO could cause a swing. 5. State the areas you would suspect as the source of water in T-250 overheads. T-240 bottoms, E-251 or E-252 and E-250. 6. State what adjustment you would make if T-250 overheads contained .22% impurities and T-260 overheads contained .20% MEA. Lower the steam/feed ratio point on T-250. 7. State what adjustment you would make if T-250 overheads contained .22% impurities and T-260 overheads contained .39% MEA. Increase the control temperature and steam/feed ratio. 8. Demonstrate how to put T-250 reflux flow on VAX control. Date Printed: April 18,1998 Paper Copies Of This Document Are Uncontrolled & Not Subject To Update.

State the purpose of MEA recycle. To drive the reactor toward more DEA production. 11. State what adjustment you would make if the TEA in T-260 overheads was .03% and the DEA in T-271 overheads was .85%. Increase the feed/steam ratio set point on T-260. 12. State what adjustment you would make if the TEA in T-260 overheads was .20% and the DEA in T-271 was .45%. Lower the feed/steam ratio set point on T-260. 13. State the set pressure on PSV-T260. 50 pounds per square inch. 14. State the set pressure on PSV-T271. 100 pounds per square inch. 15. State the parameters) on T-271 controlled by the VAX computer. None (as of the date of this module) 16. State the set pressure of PSV-E273 A/B. 100 pounds per square inch. 17. State the conditions that need to exist for packing auto ignition. Product saturated packing exposed to air at high temperatures.
