Ethanolamines/Glycol Ethers Tier 3 Procedure Section Number: Issue Number: Original Date: Revision Date: Title: References: 1120 1.4 11- 04-91 Author: Mike Viator 12- 11-95 Total Air Failure Glossary Of Equipment Identifications (Text #114) 1120. Total Air Failure 1.0 Objective: 1.1 To provide a guide to the actions that should be taken in the event of a total air failure to prevent injury to personnel and release to the environment. 2.0 Responsibility: 2.1 It is the responsibility of the operations supervisor and the senior operations specialist to ensure that this procedure is utilized in the event of a plant emergency involving a total air failure. 2.2 It is the responsibility of the senior operations specialist and the operations specialist to ensure that this guide is used in an effective manner keeping in mind that safety is a number one priority. 3.0 Special Notations: 3.1 Emergency procedures are written with the intention of having in black and white what procedure should be followed under ideal circumstances. They do not take the place of common sense. If there is a fire, we have a fire department to handle it. Don't tackle something that could injury you because you don't have the experience or training to handle it. Small fires in trash cans or some insulation fires can be handled by most of us. Don't wind up making the problem worst by getting hurt or rushing in and doing the wrong thing. The same thing applies to spills and other emergencies. ------- USe common sense------ 3.2 Amines valves that fail open in an air failure: 3.2.1 P-212 recirculation flow controller Date Printed: April 19, 1998 Paper Copies Of This Document Are Uncontrolled And Not Subject To Update.

If this cannot be done proceed with 5.2 Trip oxide to the glycol ethers and ethanolamines plants immediately. Keep ammonia and alcohol flowing as long as possible. 5.3 Announce the emergency over the intercom, stop all use of plant air (movers, impact wrenches, etc.) And sound the emergency horn. 5.4 Put the 30 pound steam controller in manual and close to prevent the valve from swinging open when air pressure returns. 5.5 Push total emergency trip for both amines and ethers plants. 5.6 Block in T-211 overheads. 5.7 Block in D-210ventto E-211/T-211. 5.8 Oxide, ammonia, alcohol, catalyst and acid controllers in manual and close. Bypass condensate around E-218 and E-219. 5.9 Block in t-250 feed, all overheads, bottoms and steam to T-110, T-115, T-120, T-130, T-140, T-220, T-230, T-240, T-250, T-260, T-271 and close steam valves to R-101/102. 5.10 Block in all rerun and recycle flows. 5.11 Coordinate actions of both operations specialists. 5.12 Close pressure controllers on glycol ejectors. 6.0 Operations Specialist Actions: 6.1 Make sure all Sundyne pumps are down and blocked in. 6.2 Block in incoming ethylene oxide at D-101, propylene oxide at block limits (if we are on the pm series) and anhydrous ammonia makeup to D-210. 6.3 Block in all transfers. 6.4 Block in T-211 overheads flow controller. 6.5 Block in D-210 vent flow.
