Ethanolamines/Glycol Ethers In Plant Training (IPT) Section Number Issue Number Origination Date Revision Date Section Test 10 1.3 06-20-92 12-29-97 :10 Author: Mike Viator Special Skills/Procedures Miscellaneous Answers: 1. State the safety valve policy for the Ethanolamines/Glycol Ethers plant. Systems are protected by two safety valves (a & b). Gate valves are to be chained, and both valves cannot be taken out of service at the same time. One must always protect the system. 2. State what the position of the valves should be when placing a chlorine cylinder in its operating position. Vertical. 3. State at what temperature the freeze precaution procedure goes into effect. 25 degrees C or below. 4. Define how the 30 pound steam header pressure is maintained. The primary source is d-510 with makeup from the 235 pound steam header. 5. State what safety equipment is needed when racking in or out a 2300 volt motor starter switchgear. A. Nomex suit. B. Hood with face shield. C. Rubber and leather gloves. D. Safety observer 6. State the definition of vessel entry as far as the S&LP is concerned. Any work on equipment which must be entered through a manhole or vessel deeper than four (4) feet including sewers, sumps and tower skirts. 7. State what must be checked prior to putting a pump in service if the motor power leads were disconnected. Pump rotation. 8. Define what special piece of equipment is needed when blowing out product lines and equipment with nitrogen.

Explain how you would put a reboiler in service. A. Take a bleed on the upstream side of the control loop through the upstream bleed. When the condensate stops flowing, reduce the flow to kept the line warm. B. With a level in the reboiler, take a little steam flow through the bypass to start warming up the reboiler itself.(About 2 units of flow on the chart) C. Take a reverse flow of hot condensate from the condensate header through the downstream side of the control loop through the downstream bleed to heat up the return line. D. After about 15 minutes in this mode of warm up, close the bypass block valve and line up the control loop. E. Call the board person and inform them that they now have control of the steam to the reboiler. F. Close all bleeds and open the condensate return header block valve all the way.
